Install BlinkRoll from Google Play, open it, and complete the required setup on your Android phone.
The front camera detects intentional eye blinks while detection is active. Camera images stay on the device.
Follow the app's prompt to enable its Android Accessibility Service. It sends vertical swipe gestures for scrolling.
Choose the scroll direction, start detection, then return to a compatible app. Blink intentionally when you want the screen to move.
Try the same vertical swipe by hand. If the screen cannot scroll that way, an eye-input gesture cannot make it scroll. Choose the matching direction in BlinkRoll. Check that camera permission and the Accessibility Service are enabled. Keep your face in view with even lighting, and check the app's detection state before trying another intentional blink.
Return to BlinkRoll and stop detection when you no longer want eye input. Screen-off and lock protection remains active. Pause eye input yourself before typing or doing anything where an unwanted swipe would be disruptive.
The front camera analyzes eye blinks on the Android device. BlinkRoll does not store or upload detection images or video.
Accessibility is used for swipe gestures, not for taps or text entry. External app types and typing states are not inspected.
Check pricing, compatibility, and safety before your first session.
Core eye input is free with banner ads; no rewarded ad or 24-hour access pass is required. Indicator hiding is a free toggle. Automatic no-face sleep is opt-in and off by default; screen-off and lock protection remains active.
Home and launcher eye input is allowed. The target screen must support compatible vertical swipe gestures; operation is not guaranteed in every app or launcher.
Commands are blocked on lock screens and when required permissions are missing or the accessibility service is disconnected. External app types and typing states are not inspected; pause eye input yourself when needed.
BlinkRoll is an accessibility and convenience tool, not a medical, diagnostic, or treatment product. Stop and rest if your eyes feel tired, dry, painful, or uncomfortable. Do not use it while driving, walking, or doing a dangerous task.
Each app has one main job. Pick the input that matches what you want to do.
Start with a familiar screen that supports vertical swipe gestures.
