Android accessibility tool

BlinkRoll

Move long Android screens up or down with intentional eye blinks. Start detection once, then keep reading in a compatible app.

Android On-device detection Up and down scrolling
BlinkRoll moving a long Android screen up or down

Start in three steps

BlinkRoll keeps setup direct: grant the required permissions, start detection, then move to the long screen you want to read.

1

Allow camera access

The front camera observes eye movement while detection is active.

2

Enable accessibility

Accessibility Service sends scroll gestures to the app currently on screen.

3

Start detection

Move to another app and blink intentionally when you want the screen to scroll.

Private by design

  • Camera frames and face images are processed on the Android device.
  • Images are not stored or uploaded by BlinkRoll.
  • Accessibility Service is used for scroll gestures, not taps or text input.
  • Detection starts and stops through user action and shows a persistent notification while active.
  • One completed rewarded ad grants 24 hours of access. Time continues to elapse while the app is closed, in the background, or locked.
