Alarm Effect: Edge Light

Know which app notified you at a glance — colored edge light per app.

Missed a notification because your phone was silent, in your pocket, or face-down? Alarm Effect lights up the edge of your screen in a color and style you assign to each app, so you can tell who pinged you without unlocking — even on the Always-On Display.

🔧 Key Features:

📌 Per-app edge lighting — choose the apps you care about and give each its own color, so a single glance tells you whether it's a message, an email, or a delivery.

⚙️ Multiple effect styles — Sweep, Pulse, Corner glow, Solid border and more, with a live preview and a test button to fine-tune each one.

📲 Customize everything — color per app, effect style, glow duration (2–8 seconds), Always-On Display wake, and pocket mode.

🔐 Needs notification access and an accessibility service, used only to draw the edge light over other apps and the lock screen — it never reads or collects screen content, and nothing about your notifications leaves your phone.

💡 Works over any app and on the lock screen, and silent or ongoing system notifications are skipped automatically so you only see the alerts that matter.

🎯 Recommended for:

- People who keep their phone silent and miss alerts.

- Anyone who wants to tell apps apart without unlocking.

- Users who like a custom, glanceable notification light.
