Stage 1 — first installable build

First installable build of LockIn — a deep-work timer that makes leaving a session cost something.

What's in Stage 1

Focus sessions

• Pick a course module, set a duration, arm a physical key, then lock in.
• The session runs in a foreground service with a live count-down notification.
• Swiping the app away no longer kills the timer: the service is sticky and re-posts its notification.

Weekly journal (new)

• Notes tab with per-week goals, checkboxes, progress rail and free-text notes.
• Everything is stored locally in Room (schema v3, additive migration).
• Open goals from last week can be carried forward in one tap.

Distraction guard (new)

• Polls the foreground app while a session is locked.
• Open a blacklisted app and a heads-up notification starts a 10-second countdown.
• Leave and the session survives. Stay and it fails with DISTRACTION.

Scanners (new)

• Full-screen barcode/QR page with CameraX + ML Kit, torch control and manual entry fallback.
• Full-screen NFC page using reader mode; reads the tag UID only.
• Both follow the app theme instead of forcing dark chrome.

Design

• Light and dark themes, three accents (blue / green / red).
• Directional tab transitions and a nav pill that travels on a spring.
• No decorative glyphs, no sparkle spam.

Install

Requires Android 12 (API 31) or newer.

1. Download LockIn-0.1.0-debug.apk below.
2. Allow "install unknown apps" for your file manager when prompted.
3. Tap the APK.

Or over USB: adb install -r LockIn-0.1.0-debug.apk

This is a debug-signed build — sideload only, not a Play Store artifact. It is 86 MB because ML Kit's barcode model ships inside it and nothing is minified yet.

Known limits

• Not yet run on physical hardware by the author of this release; compiled clean but unverified at runtime.
• Usage-access permission must be granted manually in Settings before the distraction guard can see the foreground app.
