  • Great Keto Tool!

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

    By Jarik25
    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!🙂
  • Good

    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 LLynnM
    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!
  • The best in-depth nutrition app out there

    By Bearded Iris
    I’ve tried a lot of different nutrition apps and this is by far the best one I’ve found. The detailed nutrition info — all the bitamins, minerals, etc, not just label-required minimums— is better than any other app (and given ALL such info is available free from the gov’t, the other developers are lazy), the ability to add your own recipes and set your own serving sizes is sweet, and it’s easy to use from either the website or the app. It’s nice to be able to change your goals and add in exercise as well. I bought the gold membership after two days of using it because it was clear this was what I’d been looking for. AND the developer responds to feature requests. Try it out!
  • It’s okay, but simple features are behind a paywall.

    By BranFLAYKES
    Honestly for $3 initially, the least you could do is implement the custom groups for free. The way it’s set up now just makes things messy. As a new purchaser I’m seriously disappointed this isn’t free. If I’d done more research I wouldn’t have bought this app knowing I had to pay just to get this. Also up top there should be a feature that lets you see how many calories you have left in the day.
  • Please give us offline use

    By Grassrootz
    Tried many different apps this one appears to be the best for my needs. But please consider giving us offline access. When I’m on a cruise with no internet for a week it would be nice to still count my macros.
  • Best Food Tracking App

    By Speeedbote
    I have tried many other apps(MFP, MyMacros,etc,) this one is by far the best. Great for tracking net carbs on the keto diet. Very easy to use and a colorful design. My favorite feature is that it tracks vitamins and minerals as well as macros.
