BIND_ACCESSIBILITY_SERVICE |
Draws the experimental lockscreen widget over the lock screen — an accessibility overlay is the only way a normal app can display there. The permission sounds scary, but Katapult reads only the lock screen itself — never your apps — so the widget can hide when the PIN screen appears. It records and shares nothing; this open source code is the proof. |
| Question | Answer |
|---|---|
| Will it have customizable fonts? | No. |
| Will it have a customizable grid? | No. |
| Will it have third-party icon packs? | No. |
| Will it get as many features as inkOS? | No. |
| Can I add more apps to the home screen? | No. |
| Can I adjust the opacity of the wallpaper? | No. |
| Can I change date/clock formats? | No. It follows Android settings. Change it there. |
| Can I add AM/PM to a 12-hour clock? | Yes. It's in the settings. |
| Can I reorder apps? | Yes. Long-press an app, tap Reorder, then tap another app to swap. Tap Save when done. |
| Will this launcher have a notification tray or letters screen? | No. |
Go to Settings > Notification Log and check if the notification exists in Android. Many apps require Google Play Services for push notifications. If it's not in the log, it doesn't exist for Android and Katapult can't read it.
Check the Notification Log. If Android doesn't clear it, Katapult can't either.
There are no allowlists. Go to Settings > App Notifications, tap the app, and disable "Allow notification dot".
| Katapult is free, open source, and ad-free forever. If it's made your phone better, consider supporting development. |
- The experimental lockscreen widget's approach — drawing over the keyguard through an accessibility overlay — was inspired by Lockscreen Widgets by Zachary Wander. Katapult's implementation is its own; no code was copied.
