Use these checks for common questions, contact the developer privately, or report a reproducible issue publicly.
Barometer
Barometer requires a device with a pressure sensor and may show Apple’s Motion permission dialog. The reading is processed on-device and is not tracked or sent to the developer.
Magnetic field
Field requires a device magnetometer and may show Apple’s Location permission dialog because the app reads heading sensor data. Readings stay on-device. Keep the phone away from extremely strong magnetic fields.
Private support
Email utchemnmr@gmail.com with the app version, iPhone model, iOS version, and a short description of what happened.
