All it does is count calories, even on the $10 per month plan, which I had to buy to add more than 3 items on day 1 (it is NOT FREE) Despite all the fancy talk about comprehensive macro and managing diabetes, it just track calories, protein, fat and carbs. Can't even track weight. It is easy to record meals, you can take a picture which works reasonably well or write a description. No need to guess how many grams or ounces things are.

I regret downloading this app. It’s probably the worst calorie calculator out there. You’re forced to sign up, enter your weight goals, and go through the whole setup—only to find out you can use it for just one day. After that, they lock everything behind an overpriced subscription. Total waste of time.

Really sorry it felt like a letdown. The AI scans do need cloud processing, so we offer a few free tries, then a subscription covers the rest. We totally get wanting to explore more before committing—your feedback helps us figure out how to make that better. Feel free to share more at calzen@42apps.io.
