- Fast and native — written in Kotlin with Jetpack Compose: starts in under half a second, smooth swipes and charts, a 1.8 MB APK, no JavaScript engine and no Google Play services.
- Food — 12 daily scales (calories, protein, fat, carbs, sugar, added sugar, sodium, fibre, saturated and trans fat, cholesterol, potassium) with personal minimum, target and maximum, computed from your profile, goal pace and today's activity. Limit-only nutrients show a limit.
- Fast food logging without AI — recent foods, favourites, a bundled offline database (CIS dishes plus ~2300 European foods from ANSES-CIQUAL), Open Food Facts and USDA search, barcodes, counting by pieces, custom foods based on an existing product, editable log entries and importable food packs.
- Energy balance — intake vs expenditure (BMR × lifestyle + workouts + steps), surplus or deficit converted into estimated fat mass; optional adaptive targets.
- Water — one big button for water and a separate one for other drinks, charts up to a year, recommended range and a clearly marked dangerous amount (hyponatremia).
- Activity — background step counting from the phone's hardware sensor (no Google Fit needed) or Health Connect, MET-based workout templates, custom workouts.
- Heart — blood pressure and pulse log with ACC/AHA classification and heart-rate zones.
- Body — weight trend (time-weighted average), body fat (measured, US Navy or BMI-based estimate), BMI, waist-to-height ratio, healthy weight range.
- Pantry (optional) — what you have at home, purchase and expiry dates, a freshness bar, how much is left, nutrition tags and a reminder the day before a product expires.
- Tips — fresh air, drinking water, cancer prevention, sun, back health, sleep, nutrition.
- Yours to configure — English and Russian, sections on/off, theme and accent colour, animations, goal pace slider, custom nutrient limits, JSON export/import.
Every formula and limit cites its source (WHO, IOM/EFSA, ACC/AHA, USDA…) in
Calc.kt and is covered by unit tests.
Download the APK from Releases and open it on your phone (allow installing from your browser or file manager when asked). The app can notify you about new versions (Settings → Notifications). An F-Droid listing is planned.
All data is stored only on the device. Optional network requests:
| Request | What is sent | Can be turned off |
|---|---|---|
| Food search (Open Food Facts, USDA) | the search text or barcode | Settings → Food |
| Update check (GitHub Releases) | nothing but a request to api.github.com |
Settings → Notifications |
Health Connect access is optional and read-only (steps). There are no analytics, crash reporters, ads or Google Play services in the app.
- Native Android: Kotlin, Jetpack Compose (foundation + Material 3 bottom sheets), one activity
- Hand-drawn Canvas charts, a small immutable store saved as one JSON file
- A foreground service for the hardware step counter, local notifications via AlarmManager
- UI strings in
app/src/main/assets/i18n_{ru,en}.json, Lucide icons as vector drawables - No Google Play services; the only libraries are AndroidX, kotlinx.serialization and Health Connect's client
The 1.8 MB APK starts about 3× faster than the former React Native version (0.5.x). See docs/architecture.md for a tour of the code.
Requirements: JDK 17–21, Android SDK (platform 36).
