WOOP

A calm Android planner for WOOP goal setting. It runs entirely on your phone.

WOOP (Wish · Outcome · Obstacle · Plan) is the mental-contrasting method from Gabriele Oettingen's research that Andrew Huberman covers in Protocols (Learning Protocol 2).

• Write a WOOP: one question per screen, with autosave, voice input and examples on tap.
• Check in: a one-minute re-read that tunes the plan when something didn't work.
• Reminders: nudges to write a new WOOP, plus a check-in schedule for each WOOP.
• Home-screen widget: the if-then plan of the WOOP you are focusing on, one glance away.
• Science tab: each finding the app relies on, with how strong the evidence is.

Everything stays on the phone. The app has no internet permission, no account and no analytics. No streaks, no scores.

See PLAN.md for the product, UX and architecture plan.

Install

Android: download WOOP-<version>.apk from the latest release and open it on your phone. Allow installs from your browser when Android asks. It needs Android 8.0 or newer.

An APK signed with the WOOP release key is the official build. The certificate SHA-256 fingerprint of that key is:

52:DE:1A:03:CA:19:46:EA:AD:44:98:EA:E4:E2:93:A4:2A:B4:5D:E8:8E:F7:79:1B:A4:5B:CC:87:D0:D5:9B:D4

Check it with apksigner verify --print-certs WOOP-<version>.apk, and compare the download with SHA256SUMS.txt on the release.

iPhone: there is no iOS version.

Install with adb

Requirements: JDK 17+, the Android SDK (ANDROID_HOME or local.properties), and a device with USB debugging on (Android 8.0+).

./install.sh

This builds the debug APK and installs it. With several devices connected, pass a serial from adb devices:

./install.sh -s <serial>

Or do it by hand:

./gradlew assembleDebug
adb install -r app/build/outputs/apk/debug/app-debug.apk

Develop

./gradlew testDebugUnitTest          # reminder scheduling tests
./gradlew connectedDebugAndroidTest  # Room database tests, on a device or emulator
./gradlew assembleRelease            # minified build, signed with the debug key so it also installs via adb

Stack: Kotlin, Jetpack Compose (Material 3), Navigation Compose, Room, Glance, AlarmManager. minSdk 26, targetSdk 36.
