Been using the device and getting acclimated with how to properly use it. Haven't exceed beyond level four Probably because of too much protein and not enough healthy high fat in my diet. Regardless still like the device and would recommend it to anyone who is serious about keto dieting.

The Keyto has helped me a lot. I have been staying accountable with it. I have lost over 65lbs since starting this Summer.

I love my Keyto device because it is very motivating to know where you are and have indications of how to stay in ketosis. Thank you Keyto.

This is a great tool to track your progress on keto. I was using urine strips and I could never quite tell what color the stick was or how close I was to being in ketosis. Keyto gives me accurate ratings and helps me know how my body processes certain foods. It’s great!

Works very well

Perfect and accurate solution for determining whether you are in ketosis. Far better than blood-testing or sticks. Simple, easy and convenient.

love this thing. It gamified weight loss and made it fun. At the same time it took the guesswork out of ketosis and has automatic tracking via the app. it's great, way better than those strips for sure

My Keyto is my everyday faithful friend go to guide. I rely on Keyto to keep me informed on if I’m making good food choices as I further educate myself on keto meals. I also use the resources provided by Keyto and have been able to stay on track with my diet. I’ve been on keto for years now. With Keyto I’m better informed and this system has made it so much easier and smoother for me to stay on my diet and fitness regimen. I’m very grateful to Keyto and highly recommend it!!!

Perfect size and functionality. It's great that I can keep an eye on my ketosis level with an exact number throughout the day. Additionally, the recipes and information with the app are easy to access to extremely useful. Highly recommended.

Keyto has been very helpful for my keto journey. It’s relatively quick and so easy to do. It’s portable so you can bring it everywhere with you! The app still needs some development but over all I am a happy customer!

This ketone breath tester, doesn't just tell me if I'm in ketosis, it helps me easily identify when I get kicked out. I have been able to identify calorie/sugar-free sweetners that kick me out of ketosis as well as other foods. This has been a great help to me. Thank you Keyto!

I am loving the Keyto breath sensor. It has been helpful in keeping me in ketosis. I also love the additional information regarding keto that the app provides

I love the Keyto! Its very portable and packaged nicely. Its easy to connect to my phone (Android) and easy to use. The warm up takes a while, but that's not a problem for me. Based on what I'm eating and my macro tracker, it seems to be very accurate. Its way more cost-efficient than blood checkers and I find it fun to use! Highly recommend.

Easy to use. I like knowing how I’m doing at any time.

I use this tool every time I eat to just monitor what that food group does to my score. This tool has taught me what food to stay away from. It's extremely motivating SEEING the score so you KNOW you are in Ketosis!!

Easy to use. Reliable. Great little app and amazing customer service. I highly recommend this product to everyone I treat.

Super convenient and informative…I’m addicted to it now.

I have lost 9 lbs since starting my keto journey. I would have been lost without the assistance of the Keyto device. It keeps me on track and challenges me to stay the course!

The Keyto breath sensor has become such a huge part of my daily keto routine. I would be lost without it. When I am not sure if I went over on carbs it is a life saver to quickly and painlessly check to see how light or deep into ketosis I am. It helps me dictate when the best time to eat or exercise is, I believe this product is definitely enhancing the positive results I am seeing since changing over to a keto lifestyle.

It’s simple and incredibly motivational. Don’t go a day without checking my level.

Awesome tool to check where you are at in Ketosis. I check more often than I should but I like the visual feedback I get by checking

This device makes it so easy to read ketone levels and keeps my butt on track!!! LOVE IT!!

Glad i bought it. Easy to measure results.

Keyto is much simpler and less messy than urine sticks. It’s more convenient, more portable and much more precise. Keyto has made sticking with the plan much easier. I’m down 33 lbs in 9 weeks.

I've been following the ketogenic lifestyle for over a year and the keyto has been a game changer! No more peeing on strips to test ketosis. The app functions and flows nicely and easily lets you log your weight and keyto level.
I've had non-keto family members try it to test it and I've tried it after a few cheat weekends. I loved being able to track just how long it took me to get back into ketosis.
My one complaint is I wish they showed up a numeric value for the acetone measurement in your breath, instead of hiding it behind their "Keyto level".

I was a bit skeptical about this Keyto device but I ordered it anyway. I use keto test strips along with the Keyto device to see how well he device works, and it is on point with the strips. The Keyto app is great for information and tracking. I highly recommend the Keyto device.

Great product

I've liked the device very much. Well constructed, and a beautiful design. The app is also nice, but lack integration with apple health data. I already measure my weight on a digital scale and Keyto is not able to sync. And the date from Keyto is not imported in Gyrosco.pe

I received it, unpacked it, and was off. I’ve had definite problems with keto strips. They get old, but I don’t know when they are too old to give a viable reading. Plus, I don’t need to carry and use the restroom when I want to get results which may or may not give reliable results. I can stay seated at the table or desk and get results I can rely on!

Very easy to use. Takes about a minute to warm up, then you blow. The reading comes up in seconds. App also includes recipes and meal guides for an extra fee. Highly recommend.

Great help to be able to see where I am. Had 2 other ‘meters’, and the pee sticks. This is so much easier. If I am at level 4, low burn, I can add a bulletproof tea, and jump it up to a fast burn. Definitely worth the money as far as I’m concerned.

My product came quicker than expected and I have enjoyed using it since ordering for the first time!

It really keeps me on track and eliminating guessing

Such an easy and amazing product to use! Love the fact that I can carry it around with me and to be updated of my keto levels 24/7... It felt like an eternity before I received it, but it is definitely worth the wait!

I actually have loved my Keyto pen so much that my husband ordered one too. I’m a little confused though as I get completely different readings on both pens

Keeps me in check
