New in version 0.1.20
Watched websites now work in Fulguris and more Chromium/Firefox-based browsers. Norwegian translation is complete, Defang appears under Settings > App languages on Android 13+, and Settings has a link to help translate on Weblate.
Defang is an Android launcher with an anti-dark-pattern friction layer. It is a speed bump, not a wall: you can still open Instagram, you can still override the timer. Nothing here is impossible to bypass — that is deliberate. A wall breeds circumvention; a speed bump breeds pause.
What it does:
• Intent gate — tapping a watched app shows a full-screen pause with a countdown before "Open anyway" activates. Declare what you came for, or go back.
• Session timer — a small overlay counts down your own preset limit. At zero, the end card appears. Extending costs friction: a 30-second wait, a written reason, and it works once per day. No "15 more minutes" button to tap into oblivion.
• Cool-down — after a session ends, reopening is locked for a period you chose in advance.
• Per-app grayscale — watched apps render colorless while your camera, maps, and photos keep their colors.
• Notification batching — pings from watched apps arrive as a muted summary at times you pick, not when an engagement model predicts you're vulnerable. Real contacts always come through.
• Awareness tidbits — short, specific, sourced facts about the machinery: variable reward schedules, notification timing optimization, what the algorithm selects for. They did this to you; the least you can do is know how.
• Offline prompts — when a session ends, a small physical suggestion. "Tidy the coffee table" is not a joke; it's a completable task with honest dopamine.
• Usage report — weekly time per app, per day, and how often "just checking a DM" became a 20-minute scroll. Evidence, not guilt.
Utility apps — camera, calculator, phone, maps — open instantly, always. The launcher never gets in the way of your life; it gets in the way of the loop.
No telemetry. All data stays on the device. English and Norwegian.
Requires the accessibility service (foreground app detection), notification access (batching), and display-over-apps permission (overlays). Per-app grayscale needs a one-time adb grant of WRITE_SECURE_SETTINGS — the app works without it, minus that feature.
Versions
Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

Build Log
New in version 0.1.17
Fixes a crash loop on launch and in the background for anyone who upgraded through 0.1.15. A database migration had quietly created one internal table without a required constraint; devices that already applied that migration were stuck failing an internal check on every start. That table is now automatically repaired on upgrade.
