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.
The core idea
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.
What makes it different
- Free & open source (MIT) — no paywall, no dark patterns. Code: https://github.com/apoorvdarshan/fud-ai
- Privacy-first — no account, no cloud sync, no analytics. Your log lives on your device.
- Bring your own AI — 13 providers (Gemini, OpenAI, Claude, Grok, Groq, Mistral…), local Ollama, or on-device Apple Intelligence.
- 10+ ways to log — camera, barcode, nutrition label, voice, text, manual, saved meals.
Stack
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.
