SonarPen Calibrate is the official calibration app for SonarPen, designed for Android devices including phones, tablets, and Chromebooks. This app ensures optimal performance of your SonarPen by calibrating it to your device, enhancing pressure sensing and pen stroke smoothness through a guided multi-step process. It is compatible with various SonarPen supporting apps.

The SonarPen Calibrate app requires additional apps like Flipaflip, Medibang Paint, Spacedesk, and HiPaint for full functionality. It requests permissions to record audio for communication with the phone, access photos, media, and files to save calibration settings, and network access to download pre-calibrated settings from the SonarPen server.
