Finger-based drawing using your phone’s camera.
PenFinger lets you draw directly on your screen by tracking your fingertip in real time. The app uses on-device hand-pose detection to convert finger movement into smooth 2D drawing. Tap the camera button to take a photo with your drawing and automatically save it to Photos. The preview lets you share it or return to drawing.
PenFinger respects your privacy.
• The camera is used for real-time finger tracking and photos you choose to take.
• Captured photos with your drawings are saved to Photos when permission allows. Sharing happens when you choose an action in the share sheet.
• No camera data is uploaded to the developer and no videos are recorded.
• Tracking and photo composition happen locally on your device.
Camera: Required to detect finger movement and take photos.
