Finger Blocker(Palm Rejection)

FingerRejector helps reduce unwanted finger touches while writing or drawing with a capacitive stylus. And using a capacitive disc stylus is recommended for optimal writing and drawing.

Due to Android limitations, full palm rejection is not supported. Please avoid resting too much of your palm on the screen.

By blocking touch input within a user-defined area, the app makes it easier to use a capacitive stylus on devices that do not provide dedicated palm rejection.

Permission notice

FingerRejector uses the Display over other apps permission to show its floating controls and touch-blocking area above other apps.

This permission is used only to provide the app’s core features. FingerRejector does not read, collect, store, or transmit the contents of other apps or any text you enter.

Important notice

FingerRejector does not replace hardware-based stylus or palm-rejection technology.

Because a capacitive stylus may be detected in the same way as a finger, performance can vary depending on the device, screen, stylus, writing posture, and app being used.

The app does not automatically detect and block the entire palm. It works by limiting touch input within the area selected by the user.

FingerRejector does not collect or transmit personal information.
