SO SLEEK !!! Very motivating to have this tiny, stylish and informative device in my healthy “tool-kit!”
I find I’m more aware of what I eat, as I love to get a “good grade” when I check in with my Tone Device !
Vanessa went above and beyond with her special VIP customer service, to replace a faulty unit. ( which is amazing, considering she’s having a baby any minute!!). Wishing you all the best, Vanessa !!!!! THANK YOU!
I love to support such a wonderful and important small business !!! I can’t wait to try out some more of the products !!! Joan

I love my Tone device! I am patiently waiting for the new second generation to be released!
I just wanted to say that even though I’m a guy, I like your podcast. I think a lot of us get hung up on keto, waiting for it to work it’s magic. When I’m reality, we need to eat a lot more protein and while reducing our consumption of energy.
The tone device gives us a tool to confirm that we’re remaining fat adapted, while breaking from the high energy (fat) macros.

I have had the Tone device for about a week and it has really helped me stay on track with my food choices. I'm a numbers girl and I love seeing the ketones go up every day! Understanding how those numbers relate to my food choices really works for me and keeps me headed in the right direction. I love it!

This is me 15kg lighter than I was. I love my tone device. It’s easy accurate and really helps keep me on track. It’s even helped me discover where my body is the happiest burning fat. Thank you Vanessa

I've had quite the journey with body composition. Keto & Carnivore are exactly what our bodies need to thrive. Not having to depend on Blood Glucose (finger pricks) is a godsend.
From my rough experimentation, Acetone level of 10 equate to 0.5 mm. For every 5 on breath meter equals .2-.5 increase. FYI 40--> 2.5 mm. Love the device, but can't wait till you have an ap to track and Bluetooth connectivity

Very easy to use

I just received my Tone. I have to say I am shocked! I have been keto for a couple years but have noticed that what I had been doing wasn't working as well anymore. I thought I would try doing OMAD and see what that would do. I thought I started slowly but I guess not slowly enough, I was measuring blood ketones and sugars and wasn't seeing a lot of change. I was finding it difficult to get enough nutrients in one meal, I thought it was ok I wasn't overly hungry but then my hair started falling out! I immediately started eating more and I have to say I've been a little nervous to try that again. That is when I found Vanessa, I had seen some of her other videos and loved her questions and guests. I got my Tone just in time to start PSMF. I have to say I have not seen anything other than a 4 on my meter! I am disappointed but I am also happy. There are so many levers I can use I just haven't found the right one. Being able to test as many times I want whenever I want is amazing. Now being in my 50's I am trying to enjoy my journey and the Tone has made things a lot easier. I look forward to the day that I figure this all out.
Martha B.
It’s fun to test with the Tone! I feel like my weight loss has kicked in since I started following Vanessa’s recommended higher protein form of keto!
Susan L.
I am having so much fun testing different meals, fasting protocols, and workouts and seeing how my body responds (tone numbers going up, scale and measurements going down). I’m so committed to this testing phase that I was using the Tone device in the airport and a guy had the courage to ask me what I was testing! I told him about the Tone Device and he, a fellow bio hacker, bought one one the spot! Love sharing this awesome tool with fellow health enthusiasts!
Claire E.
I love testing using the Tone and the feedback that it provides motivates me and makes me feel empowered that I am making healthy choices!
Lotta M.
It took a long time before the Tone arrived in the Netherlands (stuck in customs, with a big additional payment unfortunately), but...I'm so happy I can finally start experimenting with it. It's so motivating to be able to test whenever I want. After the first two days I'm at 25 and I more or less stay in this zone (23 to 29). Good to have the feedback that I'm consistently in fat burning mode! Next week I will switch some things up to see what happens to my numbers. Very content with my purchase, thank you Vanessa!
Lizzie H.
This device has helped me finally lose some baby weight! When I first started using it, I saw that I was consistently reading 4. So I adjusted my diet and have slowly seen higher and higher ketones, and my weight has finally gone down. I also use a body scanner instead of a regular scale and have been able to preserve muscle and lose mostly fat.
Joan K.
LOVE IT ❤️
Very motivating !!! Unlimited free testing and the battery has lasted a month so far! I’m consistently getting 22-25 during my very strict diet plan!
It’s so small and cute too ! Fits in my pocket ! Great invention !
Vicki M.
Finally received my Tone here in New Zealand it’s taken forever considering how expensive postage was. Started using it immediately as desperately need to get back into ketosis. Keeping fats high this week but will switch to PMF next week. Very pleased to see a jump from 7 to 16 after a heavy weights session. Curious to see what a 10km run will do.
Cyndi K.
After a full month of everyday use, I can say that the TONE has exceeded my expectation as a tool for understanding and amplifying one’s unique metabolic health. It’s also a great value, and I’m happy I immediately pre-ordered and invested in it.
Even with using it multiple times a day, I have not yet needed to recharge it.. it automatically turns off pretty quickly after the reading, so is energy efficient. I’ve not wanted to access the data storage yet, so can’t speak to that additional function. I’m not seeking fat loss, but I want a relaxed lifestyle and a healthy, flexible metabolism while focusing on gaining muscle post menopause. As an example, specifically I’ve learned this past month that my half-day long, weekend hikes that I love, are also crazy good for my metabolism… even better than I’d imagined, and that I can then enjoy a higher than normal carb meal afterwards (maybe wine / dessert) and my body has no problem then metabolizing that fuel… like the next morning, my TONE reading is then still in fat burning mode. In general, I’ve learned that exercise and weights for me highly impact metabolism- via testing I see a much more positive affect with movement, more so than just going even lower carb. I don’t own a bathroom scale, because the scale is a lousy measure for truly helpful and timely feedback for health. For me, I’m enjoying my food, movement and mental peace more than ever with the TONE data, because I have immediate and individualized feedback relating to my specific goals for health and lifestyle. Plus it’s so stinking cute and portable.
Rebecca J.
Long term ketoer/carnivore here! So amazing to actually see the fat burn in action! Blood ketones never seemed to be accurate for me after being in ketosis for so long! Vanessa has built an awesome product that provides a wealth of knowledge!

This device is great and is giving me a lot of good feedback on what food combos accelerate fat burning. I’m not following a strict Keto diet but more high protein and low carb, low fat. I love the immediate feedback, makes me feel like I’m moving in the right direction and helps keep me motivated and feeling positive. It’s so easy to get discouraged when trying to lose fat, this device definitely helps remove some of the guesswork! Thanks for all of the support Vanessa!
Jessica D.
Vanessa nailed it! Unlimited testing in a sleek package with comprehensive instructions and tips. And even more if you follow her on ig and listen to her podcast.
Lauren L.
I bought the Tone at the same time I started my own high protein experiment to help lose body fat. After a few weeks of using the Tone I am learning which proteins or daily combinations lead to higher breath ketone production and which foods lead to decreased ketone production. Hopefully continued use of the Tone as a tool will help me lose weight on this journey, and in the meantime, it is a fun tool to use!
John L.
As a physician I use food as medicine to treat and reverse chronic medical diseases. Having data such as breath ketone measurements is a key marker of success in fat burning and reducing metabolic disease. Up until now, unfortunately the devices available have been difficult and inaccurate to use. The Tone Device is a game changer! It is easy to use, reliable, reproducing accurate data and comes in a sleek package! I highly recommend to my patients using the Tone Device to help guide them in regaining their health as they switch from sugar burning to fat burning.
Marilyn I.
What an exciting journey this is! I started using my TONE the minute it arrived yesterday. For my first few readings, the number was consistently a 4 so after doing some research, found the instrument needed to “warm up” after it’s journey to find me in Canada. I love how it’s motivating me to eat leaner and upping my protein after eating mostly fatty meat for the first 2 years of my zero carb experience. As an older woman (68 next month) my weight loss, eating Carnivore, has been minimal but having the TONE may just be the tool I needed to get rid of the remaining weight. Thank you so much, Vanessa, for being clever enough to create this device for us! As I wait for each new podcast to continue to learn more about Optimal Protein, I will use TONE to keep me inspired to stay on track!

My tone arrived today here in Australia ! It’s beautiful in design and fits into my small clutch perfectly ❤️ I’m learning so much already - like how long it took me to get into fat burning following my high protein/fat meal. It’s motivated me so much and will help me make informed choices about what and when to eat to help me on this menopausal weight loss journey. Thanks Vanessa I love it
Lisa P.
I never considered myself to be on a "keto" diet. I first saw the Tone device introduced in your interview with Mike Collins in the Sugar Summit. I've been sugar/flour free for one year.
I use the Tone several times every day and I am always in fat burning mode. It's so motivating‼
Deanna B.
Wow! The Tone Device is Fantastic! I love how it keeps me on track with my weight loss. Thank you so much Vanessa for producing a product that is so EASY with measuring breath ketones. So much fun!!
Pam H.
I’m obsessed! Love the ease of use and great feedback I’m getting. I’ve tried a different breath meter in the past, but it never worked right for me. I’ve been using a blood glucose/ketone machine for 2 years and ketones are always low, even when I can tell I’m in ketosis. So, I’m appreciating the feedback from the breath meter. I also love not spending money on strips or having to poke my fingers! I’ve followed Vanessa since 2018 and am so happy to see her success and consider her as a keto expert I can trust! Thank you, Vanessa for such an easy to use, accurate device that I know will help me reach my wellness goals! I’ve already recommended the TONE to my other keto friends and I urge anyone who’s struggling to give it a try as it’s a game changer!!
Rachel B.
I can’t express enough how happy I am to have purchased the Tone Device!! I have been struggling to drop the weight and with this tool and seeing my numbers, it makes it so much easier to monitor which foods effect my body. The scale is finally moving!!! I love how I can use this as much as I want and no more finger pricks! When I started using I was getting a 4 reading and now I’m at 25 even between meals. It’s been a game changer.
Jennifer B.
The tone seems to work fine. I'm on a high carbohydrate diet and I get measurements between 6 and 24. I'm not in a calorie deficit at this time, so using it out of curiosity here and there. One thing I would change would be the sound. It's loud and higher pitched than I was expecting. I suffer from chronic migraines and this sound is bothersome to me. It can wake my husband in the next room. However, I realize some people may be hard of hearing and need a loud noise. Maybe a volume adjustment would be a good improvement on future models?
Julie W.
I love the Tone device ! I have been using it for more than two weeks. Started off the first few days at a 4 and now range between 15-25! It has helped me make better food choices throughout the day. I test multiple times a day. Listening to the Optimal Protein Podcast (4 years listening) along with the Tone device has really helped me Optimize my results. Vanessa is the most gracious, informative podcast host with the best guests. I highly recommend getting the Tone.’ I have pricked my finger for years but was frustrated by only seeing a “low” result. The Tone device is easier to use and gives better feedback to my exercise and diet!
Julie S.
I love my TONE so much, I'm ordering a second one! I'm completely spoiled being able to check ketones anytime I want and I love that there is a memory in case I forget to log my morning's reading. I am ordering my second one for work - I'm getting the black/rose gold this time! Now I won't have to worry about forgetting it!
Emily D.
Makes it really easy to test different ratios, eating windows etc. Also very motivating to have tangible feedback. I will be hitting my goals!
Angela N.
I absolutely love the Tone. I am having such a great time learning how differently foods and movement affect my husband and I so differently.
I also love that I have been more accountable when dining out because I am in a competition with myself to keep those fat burning numbers up!
Thank you, Vanessa, for creating this tool!
Jessica G.
The tone device is so intuitive and easy to use. It’s both beautifully designed and efficient in its functionality. It is obvious that Vanessa took immense consideration and care into creating the tone device for her community. Anyone that is invested and dedicated to their health with love this device for measuring your ketones and understanding how your body processes fuel. I highly recommend it. It’s so easy that my 4 year old loves to use it and measure his ketones for fun.
Mary H.
I received my Tone February 4. I immediately started eating higher protein. At first, I blew 12, 17, 19 and even 20. It would go up and down according to my eating pattern and exercise. The second week it reached 25 upon awaking and would go down to 22 as the day progressed. I’m in my 3rd week and this morning it was 30! I would say higher protein has elevated my fat burning for sure. Checking blood ketones only shows what is in your blood at the moment. It doesn’t tell you what you have already burned or are burning. I’m done chasing ketones! I would highly recommend the Tone over ketone meters, for sure. Eating higher protein is not for everyone, but it is what seems to work for me now that I can see the progress! Thanks, Vanessa for answering my questions quickly, and for the Tone!!!
Carole C.
The ease and convenience of the TONE device is amazing. You can carry in your pocket or bag and have it available to use anytime of the day. My healthy lifestyle lead me to be combination of Keto and Keto carnivore for at least 5 years now. However, I have never tested, so I was not sure if I was ever in ketosis or if my body was actually burning fat!
Now I know, how certain foods affect my fat burning or help excel it! I love this device!
Ann M.
Having a CGM and the Tone device has made my life so much easier to track my progress.
I carry the Tone device EVERYWHERE. I no longer need to weigh myself because my goal is to get healthier not necessarily thinner. 2022 is going to be the YEAR of health. Thanks, Vanessa for being my health coach and created this device. It motivates me knowing I am making progress. No more pricking my fingers! I was diagnosed with Type 2 diabetes and I know I am only in remission. Gotta keep my eye on the goal. Presently, I am no longer taking meds for diabetes and statin (to my doctors dismay). A1C1 went from 6.7 to 5.3 and I'm planning to keto on and focus on my higher protein way of eating (no dieting anymore).
Shannon M.
I absolutely love the accuracy and ease of use of the tone device! Thank you for making such a solid product. I have struggled with a competing brand keto breathalyzer for years & im so glad I upgraded to this one! Not only is the device amazing and easy to use, ketogirl herself is so responsive! I had a question about my levels & couldn’t find any information online since it’s such a new device. So, I slid up into ketogenic girl’s dm’s & she answered my question immediately! Oh & I also love how the readings correlate to blood levels instead of some other made-up scale!
Liz C.
I love, love, love my new TONE device! We just got back from vacation so I started at 3-4 Tuesday. Yesterday I hit 22! And I have lost 5 pounds(mostly vaca weight), eating more than I’m used to. It’s so motivating to see the ketone number rising and see when I am in the fat burning zone. I’ve struggled to commit in the past but have had a complete mindset shift. I’m convinced that mindset, tracking, and having my TONE data will keep me on track in reaching my goals! Thanks Vanessa Spina. I’m so grateful for your research, tools, tips, informing podcasts (I’m always anticipating new ones dropping), and the inspiring and thoughtful community you have created!!
Connie F.
So simple to use. It’s fantastic to know that the foods I’m eating are actually enabling me to burn fat. And I have the concrete proof!
Stacey G.
I am loving the tone device! I started using it only 2 days after I started eating low carb and I’ve seen the reading go from 4 all the way to 20 in a little over a weeks time. Seeing the numbers increase daily has really helped keep me motivated and not to cheat. It’s made it easier to say “no” to temptations because I want to stay in the fat burning zone. I definitely think it was a good investment. Oh and I also love that it’s chargeable and doesn’t run on batteries!
Melanie M.
More excited than a kid on Christmas! This is literally the most fun and interesting tool I’ve ever used. I’m a bit of a bio hacking geek and this is instant gratification! I’m only a week in and I’ve learned so much about how my body responds. Eating protein really does increase my fat burning! Definitely reevaluating my fasting protocols :)
Stefanie A.
I love how easy TONE is to use and how the immediate feedback I receive helps me to achieve my goals! I had hit a stall in my progress and tried adjusting my macros but the scale would not budge. Since using TONE just this week to adjust my macros I've been able to stay in the fat burning zone and have lost 3 pounds! Bring on bikini season! Thank you ketogenicgirl
Traci K.
Since I first heard Vanessa's podcast over 4 years ago, she is one of the main reasons why I was so successful with keto.
When I got the news that she was coming out with her own device, I didn't even hesitate to jump on it and purchase! I have easily saved over $100 in the last week and a half by not having to buy the blood test strips that cost an upwards of $20 for five little funky strips! I can test myself throughout the day multiple times a day and see how different things affect my ketone levels! Just by blowing in her machine! It is very accurate. I tested it by eating some French fries, waited an hour and then blew into it and it did not detect a ketone! Definitely will be telling everyone about this device. It must have for anyone doing keto!
Linda S.
Absolutely loving the unlimited testing and reassurance!
I'm extremely impressed with this device. I've used just about all the ketone measuring devices on the market and the Tone Device offers some pretty incredible differences:
•Accuracy at low ketone levels
•Unlimited testing with nothing more to purchase
•Quiet, fast, extremely portable
•No finger pricks
The Tone is so helpful! It lets me easily see how what I'm eating affects my ability to burn body fat for fuel. There's often a fear that a higher protein approach can kick people out of ketosis, but with the Tone, I can get unlimited feedback on how higher protein is really working for me!
I'd highly recommend this device to anyone who is looking for solid reassurance that their ketogenic diet is working for them. The realtime feedback is invaluable for evaluating or making changes to how you eat. People can stop wasting time with foods or macros that aren't helping them reach their goals!
I'm using it multiple times a day and it's holding its charge very well. It worked for me straight out of the box, and I haven't had to charge mine yet. I'd give six stars if I could!
Roxanna W.
I love the unlimited testing!
I have already upped my protein intake because now I can see that a higher protein approach isn’t kicking me out of Ketosis!
Alysia O.
I am absolutely OBSESSED with the Tone Device! I use this, no joke, every hour or two . I love that I now know exactly what my body is doing and confirms my healthy eating choices are working. I’m so happy Vanessa created this. It’s so affordable and convenient, I LOVE that I have an unlimited amount of times that I can . Thank you Vanessa
Dawn G.
I’ve had my tone device for about a week now and it is amazing being able to check numbers multiple times a day on the go at work anywhere! I find myself wanting to make better choices in what I eat to keep my numbers in a good place!! I think this little device is going to be a game changer for me!! Never poking my finger again!!! Thank you Vanessa for working so hard to bring us such an awesome tool!!
Bill K.
So perfect and reaffirming! I've been very well fat adapted(low carb) going on 5 years now. Initially my blood and urine ketones were off the charts. For the last 2+ years they have been low (ketones average .4-.6) but I can always taste ketones in my breath and my blood work is excellent. I've often wondered if I'm in a low or high fat burning state, even though I feel like I'm in my low 40's(about to turn 61). My first reading was 25, next morning 33. That answers my question! Love the confirmation that all is still going great and so simple to use. Time to sell my Precision Xtra and strips. The Tone device is the perfect tool to help guide your way to better health! Thank you Vanessa and keep doing what you do, you're spot on, especially in regards to protein! ;)
Leigh B.
I love this device! I’m testing with different fat to protein ratios to see how my body responds. Very insightful! Thank you, Vanessa , for creating an easy to use product!
Michelle D.
Creating this tone device was genius idea! Thank you!
My focus is eating optimal protein…100-180g a day. I have consistently been getting readings from 7-10 which I’m thrilled with!
Now I’m motivated to pay attention to carbs and fats I consume and see how I can increase fat burning.
Very cool!
(This morning it was 18!)
Brandi P.
The Tone Device is brilliant. There is no waste, it is portable, it is easy to use and gives real time feedback whether your body is burning fat. I took my first reading after a 19 hour fast, which was 25. I took my second reading first thing this morning, which was 11. I plan to use my readings to tailor when and what I should eat to stay in fat burning mode. Ms. Spina has knocked this one out of the park.
Denae P.
I was on the fence about getting this gadget. A low carb approach has been my lifestyle for seven years now, and have great success using the principles Vanessa shares. I never utilized test strips because of cost. I am so excited to have personal numbers I can see almost instantly, and track my progress as I hone in to what macros are best for me. Don’t think twice about getting this, it’s so fast, convenient, and easy to use!
Allison B.
The Tone device is a game changer! I've been keto carnivore for 2.5 years and have used a blood monitor when I've tried tweaking my macros. The Tone makes it SO much easier and NO FINGER PRICKING! I can test as often as I want without pain or worry about refilling supplies that always felt a bit wasteful too. It is worth the investment! Thank you for this, Vanessa!!
Robin L.
Love the Tone Device!! So much fun having the freedom to check ketone/fat burning levels multiple times per day without sticking my finger or having to buy strips. I can check on waking, after eating every meal, before and after working out, etc., etc. without having to think twice about how much it will cost and how much it's going to hurt sticking my finger yet AGAIN! You get real world, immediate results. Such a great product created by Ketogenic Girl, and also love that I am supporting a woman-owned small business and at the same time doing something good for myself...makes the initial investment 1000% worth it! If you are on the fence, go for it, you will not regret it.
Kellie B.
The ability to have a rolling snapshot of my personal ketone levels is priceless. Learning what effects your levels; positively and negatively is so important, but was unavailable to me until now. The Tone device will allowed for ease of testing with diet, exercise, stress management, sleep, really in any situation! Its the easiest "test" I have ever taken! Blood testing was expensive and inconvenient, but with the Tone I can test whenever and wherever I want, and know it's accurate! A true bonus for me is how travel friendly this device is too! I am excited to use this tool on my journey of health and towards my body composition goals! Thank you Vanessa for developing this tool! Game Changer!
Jill C.
I love this!!! It’s the easiest ketone reader I’ve ever used, and I have tried them all! So easy to use straight out of the box! It’s very portable and light weight. I can take it anywhere!! I love that it eliminates all the finger pricking and it eliminates so much waste from all the packaging of the finger prick devices and the urine strips. Bravo!!!
Lauren J.
The Tone is the BEST investment!! I no longer have to prick my finger to test my ketones and it helps me so much to learn when my body is burning fat. I love how much money I am saving on expensive test strips and I can test as many times as I like! It is amazing I absolutely love it!!
