Easy Keyto to Keto

I love this new innovative tool to let me know when I’m in Ketosis. It is so easy to operate that I bought one for my senior mom to monitor her Ketosis as well. Being in Ketosis is the only way I can keep my diabetes under control. Thank you!

Great Product, Very Motivating

Ive been using Keyto since April and I love it! Simple, Effective, and super motivating!!!

This Keyto system is Awesome!

I’ve been up and down with weight all my life. Plus or minus 5kg. As I’ve got older it’s been so much harder to lose weight. Tried so many things but this has been incredible. Within 6 days of strictly following the meal plan and really only light exercise (4-5km walk a day), I got my Keyto rating up to 6 and have lost 2kg already. I feel great, sleep well and am not hungry at all. I also just stopped smoking which made it more surprising as I was expecting to put on weight. Highly recommend this easy to follow and actually quite a fun eating plan.

Science-based, high tech way to monitor ketosis

I have been keto; i.e., following a ketosis-based metabolism diet, for quite some time. I lost over 60 pounds and at 65 years old my health markers show me to be at elite athlete level. For me, the Keyto is just pure convenience as I have used both blood test and "Keto-Stix" (urinalysis) in the past to monitor my ketosis level. The Keyto is just fantastic. You can use it anywhere and as often as you like (the single AAA battery has a phenomenal lifespan!). This is very important to me as I carb-cycle around my fitness regimen. I like to call it 'keto-surfing' because I will dip in and out of ketosis around my workout cycles. I also do a lot of biohacking and the Keyto is just perfect for homing in on exact carb levels for supporting muscle hypertrophy while minimizing lipid storage. I just can't say enough good things about this device.

For people just starting a keto diet with the intent to lose fat, the Keyto diet protocol cannot be beat. No calorie counting, eat until satisfied, easy food labelling (colors) and just good nutrition that includes fiber and micronutrients. The diet could not be simpler and the results are nothing short of spectacular and the Keyto provides that extra incentive to stay the course and drop the weight.

Great way to keep yourself in check

It’s a super convenient way to keep track and correlate how food choices affect ketone levels. There are no consumables other than the battery which lasts a long time. Highly recommend for anyone living or trying to live a low carb lifestyle.

Amazing

Honestly I can’t say enough good things. As someone who has used ketosis for weight loss and lifestyle I love the fact that it lets you know right where you are from the start of your journey on. So when you’re feeling bad in the beginning it’s easy to look at your number and see exactly where you are and it gives you motivation to keep going. The app is incredible, lots of tips and helpful information. It’s easy to use, accurate and so much cleaner than strips. The other testers that use your breath don’t test properly and do not use the proper aspects of your breath for the most accurate reading. All in all, it’s easy, convenient and accurate. What more could you ask for.

Do yourself a favor and buy this now.

There’s nothing better than instant feedback. I’ve tried many “diets” and stopped because I wasn’t sure if it was “working.” This, however, is science. If you’re eating correctly, the body will do its thing. How do you know if you’re eating correctly, Keyto will tell you. Use the pen and you’ll know instantly if you’re in ketosis and continue to test to make sure you stay there.
The app has tons of recipe ideas. It may sound corny, but it’s fun.

Keyto Breath sensor pretty good

I bought this sensor a while ago but have not been doing keto as much as I like. I travel a lot and it is hard to follow when on the road. However, no more excuses. I have a blood ketone “machine” as well and 1.5 on that is “5” on this sensor. So still trying to associate all the numbers but so far, the Keyto sensor is good! It is light and no more expensive strips to use 3x daily. Just blow. Takes a while to calibrate but oh well. The 7 day Trader Joe plan is awesome!! Get one!! Well worth it. Getting the upgraded app will help as well but I’m sure that you can do without if money is tight. Cheers!

Works perfectly!

I’ve used ketonix, and test strips. Keyto is so much easier, including warming up more quickly so I don’t waste as much time, and I appreciate that it's BlueTooth to my phone, unlike other solutions. Perfect product to track my Keto levels.

Helps to Pinpoint Very Well

I love this because there were foods that I wasn’t sure about...like some dairy and low carb sweets...and this really helped to pinpoint trouble spots. Plus, it is a great positive reinforcement for the days where my motivation lagged. Also, really helpful when traveling, and the small size packed well. Well worth it’s price.

Motivation

Having the Keyto has kept me motivated because now I know when I am in ketosis and that makes me want to stay in ketosis. I am very happy with my Keyto and I highly recommend it.

Awesome tool

This device is so much better than pricking your fingers for blood testing. Handy and portable!

Good devices, but no need to have location services for the app

I'm happy with the device and the app. However, one major problem is with the app requiring access to location, which shouldn't, only bluetooth is needed. I'm a developer myself and know about this stuff. I'd like to see this removed in the next update, otherwise I see this as a privacy breach.

Thanks

Amazing

This unit has changed my life. No more guessing if i am in ketosis.
Quick and easy test and very accurate. Thank you Keyto

It works, its excellent, and its fail safe

Early backer here! Im UK based, and this has been incredible. Its so incredibly accurate it wonderful. Ive tried skewing it by maybe having over non-ketoers try in in direct succession, or by doing it with a half breath, or shortly after vaping, or after a drink (one not 5 mind you) and its always correct and amazing. Ie been using it every day for about 4-5 months, and it still has yet to run out of battery. Diet wise, its been great, losing consistent weight and looking and feeling great. Never been a fat girl, but just a bit over 'normal teenage girl' size (extra 10 kilos) so not much but not too bad either. and so far its just been great. Falled out of ketosis in and out a couple time, but every time i get out of it and decide im bored of it and just wanna eat a pizza, i realise suddely how sh*t i feel all the time when im on carbs and how tired and lethargic i am. not gonna lie, its even gotten so good i want to read more, do better at uni, do better at sports and so on. I am a very very logically minded person, and require accurate data on things, so having a consistent monitor is great. and every time i think "nah its not worth it its too hard" and i go back to carbs, i realise "no its not worth it to exchange a temporary pizza break with the months of hard work and the headaches and stomache aches resulting from car bs arent worth it either". not allergic to anything, its just odd how much you realise your 'normal' aka bloating and tireness you feel when on carbs, when you suddenly get out of it all. its odd, i kept on hoping keto was just a joke trend, like a cult people were part of to think they were better than you, but no. its all true. it really is as good. innitially, yes not gonna lie the headaches were annoying, but *pun intended* - it was all in my head. afterwards, smooth sailing. couldnt have done it without the accurate measurement. now im on the website getting for my mum, and see i can write a review, so i thought, people needa know. cheers! A

An Awesome thing!

This is a well thought out product....I have been carnivore for 450 days now and in deep ketosis at 8 .This is something I struggled with before the keyto breath sensor....once you learn to relax and breath ....you are on your way.......Happy breathing🌹
I really do have to say that this is a well thought out product ....WELL WORTH THE WAIT🔥

This thing is awesome!

Knew nothing about keyto diet. The app guided me through everything I needed to get started. Feeling way more energy after a week. Glad I got this!

Great product

I have several other ways of measuring Ketones including other breath devices. This is the lightest and easiest to use of the group. And I have found the accuracy to match my blood strips on a regular basis.

Excellent Better Health Innovation Tool

Full marks to the Keyto team. Excellent updates and support. Product is professionally packaged and the device is robust and well made. Keyto App is easy to navigate and provides very helpful insights for selecting the right food diet and better health.

Fabulous motivation!

I love my Keyto! Once you get the hang of it, it is very motivating to track your keytones accurately by just breathing into the sensor. It has shown me which foods work best for my Keto journey (or not!) as well as which fasting schedules are best for me. I know I can just fire up the Keyto, blow and gauge my progress. Thank you! As an aside, the app has fabulous resources, recipes, even a week meal plan with a shopping list - love it!

Excellent product. Excellent after market service!

Yes they want to to buy their Keyto Pen, I own 2, but they don’t stop there. They want you to succeed and have amassed all kinds of help readily available to you. Take the dive, buy a pen. It tells you exactly where you are and where you need to go. You won’t regret it!

Works perfectly

Nothing much to say. Just works great and do what it has to to.
I would buy it anytime again.
Less 20 kg since i have it!

Super Easy Keto Breathalyzer

I purchased Keyto for its simplicity. I didnt want to do the keto blood tests & the keto urine strips are just not great. I used Keyto for about 2 months straight. I found it easy to use, and easy to understand. I never had any issues while using it other than having to change the battery. I think its a great tool for anyone starting out whose looking for a simple way to determine if they are in ketosis. I will continue to use mine!

Easy!

I love being able to easily keep track of whether I'm in ketosis or not with the Keyto. I was using expensive blood testing strips, so limited my use of them. There's no need to with the Keyto!
