What it does

Notifications that stay useful without taking over your screen.

Floating overlay

Draws a compact, custom overlay above other apps using native Android window manager APIs.

Smart notification cards

Converts active notifications into glanceable cards with open, dismiss, and direct action support.

Wavy music seek bar

Renders playing progress as an organic, animated wave with circular thumb drag-to-seek support.

Interactive customization

Lets users adjust island width, height, vertical offsets, and corner radius dynamically from the app.

Reorganized dashboard

Reorganizes the main settings screen into clean topic cards (Permissions, Positions, Support, About).

Live session sync

Synchronizes playing status, repeat/loop modes, and song favorites in real-time with background players.

Local first

Built around transparent permissions.

Smart Island processes notification data on the device, stores preferences locally, and currently does not request the Android INTERNET permission.

SYSTEM_ALERT_WINDOW

Displays the floating island above other apps.

BIND_NOTIFICATION_LISTENER_SERVICE

Reads notification metadata for notification, call, and media states.

FOREGROUND_SERVICE

Keeps the overlay active while Smart Island is enabled.
