The app uses AI to estimate calories and macros from a photo of a meal, stores all data locally, and requires no account or subscription.", "body_md": "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.\n\nPoint 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.\n\nSwiftUI on iOS, Jetpack Compose on Android, all data local (UserDefaults / on-device storage), keys in the Keychain / Android Keystore.\n\nIf a free, private calorie tracker sounds useful, try it at [https://fud-ai.app](https://fud-ai.app) or star the repo.
