Heavyn't

Minimal black & white Android workout tracker. Logs the weight on every exercise and colours an anatomy map: blue = strong, red = weak.

Features

• Home: today's workout + front/back body map scored from your lifts (estimated 1RM ÷ bodyweight vs. an intermediate lifter, best set in last 90 days)
• Plans built from an exercise drop-down; any on/off cycle (7 on / 7 off preset, or set every day yourself)
• Workout: tap an exercise to complete it, hold to change sets/reps/weight. Weights save to the plan by themselves (sets/reps changes still ask); once an exercise has a weight, one tap checks it off
• Plateau prompts to raise the weight after N sessions (default 3) or ~4 weeks at the same weight
• Workout date & time recorded automatically; per-exercise weight history and charts
• "Bodyweight" on an exercise logs the bodyweight from your profile; on the 1st of each month a notification + in-app prompt asks you to update it (skipped if you already did that month)
• Add your own exercises in-app; optional reminders on workout days; copy/paste backup

Native app (v3+)

native/ is a true native Android app (Kotlin + Jetpack Compose), not a web view. It reads the same JSON backup format as the original web/Capacitor version (src/ + android/, kept for reference), so data can be restored straight across.

.\scriptsuild-native.ps1                  # tests + signed APK -> dist\heavynt.apk
.\scripts
elease-native.ps1 3.0.1 "notes"  # builds + publishes a GitHub Release

node scripts/gen-kotlin-data.mjs regenerates the exercise library for Kotlin from src/data.js.

Develop (legacy web version)

npm install
npm run build        # bundles src/ -> www/app.js (open www/index.html#home in a browser to preview)
npm test             # logic tests
.\scripts\build-apk.ps1                      # signed APK -> dist\workout-tracker.apk
.\scripts\release.ps1 1.0.1 "notes"          # builds + publishes a GitHub Release

Needs JDK 21 and the Android SDK (ANDROID_HOME, default C:\Android). Releases are signed with keystore/release.jks (git-ignored, back it up: without it updates can't install over the old app). Bump versionCode/versionName in android/app/build.gradle for each release.

Starter exercises live in src/data.js; add more there or in the app's Exercises tab.
