Chompass

Ad-free AI calorie tracker. Snap, speak, or type meals. Open source.

Chompass is an ad-free, privacy-focused calorie tracker forked from Fud AI. Log meals with photos, voice, barcode scans, or text. Bring your own cloud AI key (Google AI Studio, OpenRouter, etc.) or use optional on-device Gemma 4 inference. Nothing is sent to a server unless you choose a cloud provider.

Food logging • Multi-photo capture, share-into-app, voice, barcode, manual entry, saved meals and recipes • Barcode scan with Open Food Facts lookup (4.6M+ products, cached for offline use); photo analysis can read codes from the image • Optional on-device AI (Gemma 4 via LiteRT-LM): one-time model download, opt-in, arm64 with 6 GB+ RAM

Progress & health • Live calorie budget: the home ring grows your daily goal with the day's burn, measured via Health Connect, added manually, or estimated from your 14-day active average • Weight, body fat, calorie history, goals, steps and exercise • Health Connect sync (two-way): write meals, weight, body fat, height; read sleep, heart rate, hydration, steps, energy • Optional local water tracking and home-screen widgets

Privacy • No ads, no analytics SDKs, no accounts • Local-first storage; encrypted API keys on device • Diary and body-metrics export (JSON, Markdown, CSV)
