I’ve used many food trackers and this is by far the easiest I’ve ever used and I love it. Snap a picture and it thinks for a minutes and boom… food logged. You can make adjustments after, which is great. I had a taco salad and was able to delete the shell that I don’t eat and add the avocado that was hidden in the photo. The only things I would change is to be able to select/change the measurement from grams to cups or ounces. I don’t know how to visualize grams so it’s difficult to tell if the sizing/amount is accurate. And I would like to be able to connect it to my scale and the Health app to share information. Otherwise it’s a great app. My doctor will be happy I’m finally tracking my intake. ### 5/5 — Amazing App *2025-05-03* I am able to eat whatever I want and all I do is snap a photo and I feel healthier and have already lost weight and am paying attention more to what I am eating and doing. **Developer response:** congrats on your progress, and thank you for the kind words! ### 5/5 — amazing amazing amazing *2025-03-08* can track all sorts of nutrients and maintain gaining weight **Developer response:** tae thanks for the kind words. glad you're enjoying the app! ### 5/5 — Super easy to use! *2025-02-01, version 1.0.46* Loving this app so far ### 5/5 — Calorie *2025-01-31, version 1.0.46* This app is majic I love the ai ### 1/5 — Maybe need to fix a bug ? *2025-01-14* The app just stopped working mid me setting up the app..
