FoodYou Review
A polished, privacy-first Android/iOS food diary and nutrition tracker built with Kotlin and Jetpack Compose.
Each review covers deployability, value versus commercial alternatives, and privacy model. Tools that can run locally were started and exercised; mobile or backend-dependent tools were assessed from published builds, source code, and deploy guides. Ratings reflect what we were able to verify.
FoodYou — Open Source Privacy-First Nutrition Tracker
A polished Android/iOS food diary and nutrition tracker built with Kotlin and Jetpack Compose. Last updated: 2026-06-21.
One-sentence verdict: The most credible open-source daily nutrition tracker in this batch — a real alternative to commercial food diaries for users willing to install from F-Droid or sideload an APK.
What the System Is
FoodYou is a free, open-source mobile nutrition tracker written in Kotlin with Jetpack Compose. It is published on F-Droid and GitHub Releases. The documented architecture includes:
- Local data only: Uses Android Room with SQLite for on-device storage.
- No account required: The README states "all data stored locally on your device."
- Multi-platform Kotlin:
build.gradle.ktssets up Android plusiosArm64/iosSimulatorArm64targets. - Barcode scanning: Depends on a shared
barcodescannermodule pluszxing-android-embedded. - Network layer: Uses Ktor to query Open Food Facts, USDA FoodData Central, and the Swiss Food Composition Database.
- Modern UI: Material Design 3 / Material You dynamic theming, paging, reorderable cards, and a color picker.
Because this is an Android/iOS project, it is not run as a local web service in the server environment. The assessment below is based on the published F-Droid build, source code, and metadata screenshots.
| Key data | |
|---|---|
| Category | Fitness & Nutrition |
| Language | Kotlin / Jetpack Compose |
| License | GPL-3.0 |
| Self-hosted | No server; data stays on device |
| AI | None |
| Database | Android Room / SQLite |
| Distribution | F-Droid, GitHub Releases |
How to Install and Deploy
Option 1: F-Droid or GitHub Releases (recommended)
Download the APK from the project's F-Droid page or GitHub Releases and install it on your Android device.
Option 2: Build from source
cd /data2/docker/going-global/repos/FoodYou
./gradlew assembleDebug
adb install app/build/outputs/apk/debug/app-debug.apk
Requirements: Android Studio or Android SDK, JDK 17+, and an Android emulator or physical device.
How to Test
The documented test flow for the mobile app is:
- Install the APK on an Android device or emulator.
- Open the app and verify the onboarding flow.
- Search for a food using the barcode scanner or text search.
- Log a meal and verify macro/micronutrient totals update.
- Create a custom food if needed.
- Check that data persists locally without requiring an account.
The current server environment has no Android SDK or emulator, so this test flow is documented for reference rather than executed here.
Privacy & Compliance
FoodYou is designed for personal fitness data, not protected health information (PHI). It does not claim HIPAA compliance out of the box. Because data stays on the device, the privacy posture is stronger than ad-supported commercial apps. Backups are the user's responsibility.
