Good app that’s getting better

App got fixed, and unnecessary audio was removed as well. It’s now much less invasive, and easier to use. Well done!

I bought my Keyto device to read my blood ketone levels, natch. I don’t care about their app beyond getting those readings. Of course the app is always nagging me for more attention and more personal data, which until now has been avoidable, if annoying. No matter how hard the developer tries, I’m not going to shift the management of my health tracking data into their app. I just need the app the get the ketone reading out of the device I purchased. But with the most recent app update, I can no longer just get my ketone data from my device without entering a number of personal metrics into the app. This is a deal breaker for me, and has now rendered my Keyto device unusable. Like so many people, I am exhausted daily by the many information-sucking monetization strategies employed by companies today. Keyto: The best relationship you can build with me is to keep your device simply doing what I bought it to do: measure my ketone levels.

Surprise! I adore this entire package! And I’m staying in track!

I tended to stray from my weight and health goals daily, promising myself... ok... I’ll start again tomorrow. Well, hundreds and hundreds of tomorrow’s later, I saw this on my Instagram. So, being the tech geek that I am, I ordered it. It was so much fun and it made me an honest woman within a week. I can’t hide anymore with my new toy! It’s fun to use it after eating to see what affects my Ketosis. I feel wonderful! I’m losing unwanted pounds, and I’m having fun, while learning to be true to myself. Good thing. I also got a Keyto box full of incredible snacks and foods. The app is a great resource of data I never knew. Loving this!!! Thank you!

Update: still loving this product! It keeps me honest! ❤️❤️❤️❤️❤️

Amazing device!!!!

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.
