Chompass - Calorie Tracker: Log Meals Smarter

Chompass is a calorie tracker by fitguy that helps you log meals and monitor your health metrics with a focus on privacy and an ad-free experience. It is an open-source app that lets you record what you eat using photos, voice, barcode scans, or manual text entry. The app is designed for people who want a straightforward way to manage their daily calorie intake without the clutter of ads or mandatory cloud accounts.

Chompass builds on the foundations of the Fud AI project, offering a local-first approach where your data stays on your device unless you actively choose to use a cloud AI provider. You can bring your own API key from services like Google AI Studio or OpenRouter, or rely on the optional on-device Gemma 4 inference for meal recognition. This flexibility means you control where your data goes—whether you prefer the convenience of a cloud service or the privacy of keeping everything local.

Version 5.5.2, released on October 14, 2026, continues to refine the logging experience. While the changelog specifically mentions improvements to the barcode lookup and photo analysis for reading codes from images, the app also remains compatible with devices running Android 8.0 and above. The latest update maintains the core features: multi-photo capture, share-into-app, voice logging, and a live calorie budget ring that syncs with Health Connect. With a file size of 20 MB, it is a lightweight addition to your health toolkit.

How to install

1. Tap the download button on this page to get the APK file (20 MB).

3. Open the downloaded APK file from your notifications or file manager.
4. Tap 'Install' on the installation screen.
5. Once installed, open Chompass from your app drawer.
6. Ensure your device runs Android 8.0 or higher to install and use the app.

Chompass is ideal for privacy-conscious users who want to avoid ads and data collection, fitness enthusiasts who already use Health Connect and want a comprehensive calorie and health tracker, and people who prefer flexible logging methods—whether snapping photos, speaking, or scanning barcodes—without being locked into a single workflow.

For the most accurate barcode recognition, ensure good lighting and hold your phone steady when capturing a photo of the product label; the built-in photo analysis can read the code, but a clear image speeds up the lookup.

Chompass is a solid choice for anyone who values privacy and flexibility in a calorie tracker. Its ad-free, open-source nature sets it apart, and the variety of logging methods makes it adaptable to different habits. The need to bring your own AI key for cloud features might be a hurdle for some, but the on-device option and local-first design compensate. Overall, it is a strong, user-controlled tool for everyday health tracking.
