Most calorie trackers have drifted into the same place: a subscription wall, ads, a mandatory account, and your eating data quietly monetized. I wanted the opposite, so I built **Fud AI** — a free, open-source, privacy-first calorie tracker for iOS and Android.

Point your camera at a meal and the AI estimates calories + macros in seconds. No scrolling a database of forty "grilled chicken" entries. If the guess is off, you unlock and edit before logging.

SwiftUI on iOS, Jetpack Compose on Android, all data local (UserDefaults / on-device storage), keys in the Keychain / Android Keystore.

If a free, private calorie tracker sounds useful, try it at [https://fud-ai.app](https://fud-ai.app) or star the repo. Feedback very welcome.
