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 or star the repo. Feedback very welcome.
