  • Fair start

    Doesn’t track time of entry. UI is subpar and completely unprofessional. Fields are presented under the keyboard so you can’t see what you’re entering. Portions are really strange... like, 8oz portions here where the bottle says 2 x 9oz portions, plus the field is hidden under the keyboard. The basics are here, though. Would be nice if they could get it right.
  • Perfect for Keto

    I’ve bought this app twice. First on Android and now for my iPhone. I live the Keto lifestyle and count net carbs and this app has Ketogenic diet setting in it. You can even adjust your macros by gram. Very extensive nutrients meters.
  • Great App

    This has taken my health tracking to a new level. I am a gold subscriber and I do love the time stamp feature. One tweak would be to change the time stamp when you copy from a prior day. Thanks for being so responsive.
  • this thing is great.

    Great app. This can be the core of any smart health strategy. Cleanest Ui Rarely crashes.
  • Great Keto Tool!

    I love this app. Much better than MyFitnessPal. Helps me keep Keto macros in check. I align it with the ketogains calc goals.
  • Great!

    I loved this. And I bought the subscription thinking it would have a real search not a list search. Bananas do not scan so I couldn't add my banas for the day. Otherwise I 🧡🧡🧡🧡the app!🙂

    UPD. Still have this problem. BTW, love the new design. UPD. Everything works fine. All notes are now at the bottom. Can't change the order of entries.
  • Shouldn’t have purchased

    By LynnMUR
    Not at all pleased. Difficult to you. Whatever I enter there is mo item it will record. Waste of money
  • Almost perfect

    By Justkal
    I have had this for a few months. And I mostly love it. But it really bugs me that all the nutritional information when comes to size and amounts is horrible. How about you put in .....piece, cups,oz, tbsp, tsp, etc. this converting everything to grams is a lot of wasted time, I could be exercising my body instead of my brain. I take photos of items and it says I will be contacted when the item is added. Never seen any yet. So don’t believe this. So get this one thing right and I will stick around.
  • Tracking by Keto

    By Starsfan7
    Sure wish I hadn’t purchased this app. Every time I try to enter my custom numbers from the Keto Calculator it changes them. I’ve tried under Keto and under custom. Simply does not work and under a review below where you told a commenter to “relax it’s just a bug” that tells me everything I need to know about your customer service. Ridiculous. Bye!
