macro is a meal and nutrition tracker for people who want logging to stay simple. Describe a meal, snap a photo, or scan a barcode — the app estimates calories and macros with AI, tracks your daily targets, and keeps your data on-device when you're offline.
It started as a side project for a friend who found other trackers too expensive and complicated. The focus has stayed the same: make everyday meal tracking fast enough that you actually stick with it.
