PenFinger

PenFinger lets you draw on your phone using just your finger.

By tracking your fingertip with the camera, PenFinger transforms real-world hand movement into 2D drawings directly on your screen. Move your finger in the air and watch your strokes appear. Close your hand into a fist to pause drawing.

Features

• Real-time fingertip tracking, including when the lower palm is outside the frame
• Eight ink colors with a palette of colored circles
• Separate strokes that retain their original colors
• One-tap clearing that keeps your selected color
• Photos with your drawing, automatically saved to Photos when permission allows
• A photo preview with sharing and save confirmation
• On-device camera processing

Privacy First

Camera tracking and photo composition happen on your device. The developer does not receive your photos or drawings. Photos permission is used only to add captured images to your library. Sharing happens when you choose an action in the share sheet.

• Students and educators
• Anyone who wants to experiment with gesture-based drawing
