FitBuddy

FitBuddy is a free, open-source health tracker for Android, with region packs that personalise diets and daily routines.

Snap a photo or type what you ate — an LLM estimates calories and macros instantly. Review ingredients, tweak weights with live macro recalculation, and save. Bookmark favourite meals as presets for one-tap logging next time.

Features:

• Region packs — personalise AI prompts, staples, portion language, and log examples to your region

• Smart logging — photo or text; AI parses food and exercise automatically

• Meal review — edit dish name, adjust ingredient weights with live macro recalc

• Editable workouts — structured sessions with a 1,500+ exercise catalog (demo GIFs via CDN), favourites, body-part/equipment filters, recent & frequent picks, AI session names, and upgrade for simple logs

• Presets — searchable saved foods and meals; recently used on top; one-tap log

• Barcode scan — look up packaged foods; save or log them, and contribute missing products through Open Food Facts

• Dashboard — daily calorie ring, combined food/exercise log, macro breakdown

• Body goals — track weight, body-fat percentage, BMR, and muscle mass; current weight follows the newest reading; manually save calorie and macro targets, or calculate fresh adult targets with transparent Mifflin–St Jeor/TDEE estimates, quality-gated weight/body-fat/muscle trends, bounded AI-assisted personalization, activity guidance, and cautious weight milestones; AI can choose only between exact plans generated safely on-device

• Analytics — weekly or rolling 30-day calorie intake vs target, target-weight body charts, and a compact GitHub-style six-month calorie-burn heatmap

• Encrypted backups — AES-256-GCM; gzip; optional cloud with append-only chunks

• Loading animations — choose Analyzing / Insights wait animations in Settings

• Auto failover — rotates API keys and models on rate limits; stays on your preferred platform

• Offline fallback — works without an AI key via built-in simulator

• Developer support — Razorpay UPI/cards for India and GitHub Sponsors internationally; optional reminder every few days (turns off when your Support ID is on the public supporter list); thank-you cards for named supporters

• Material You — dynamic color theming on Android 12+

• Crash reports — optional anonymous Sentry reports (off by default; opt in via Settings)

• Diagnostic log — optional AI connection log you can export from Settings for support (no meals, photos, or keys)
