AI Calorie Tracker — Snap a Photo of Your Meal, Done
Take a photo of your meal. AI identifies every ingredient, estimates portions, logs calories and macros. No typing.
The Problem
Calorie tracking apps require manual search and entry for every food item. 90% of users quit within 2 weeks. Photo-based tracking exists (SnapCalorie) but accuracy is poor and coverage limited.
