 ## Calibration
 
-Calibration removes sensor drift and improves accuracy. The device must be **stationary** during calibration.
+Calibration removes sensor drift and improves accuracy. The device must be **stationary on a flat surface** during calibration.
 
-### Manual Calibration
+### Using the Built-in Calibration Tool
+
+The easiest way to calibrate your IMU is through the Settings app:
+
+1. Open **Settings** → **IMU** → **Calibrate IMU**
+2. Place your device on a flat, stable surface
+3. Tap **Calibrate Now**
+4. Keep the device still for ~2 seconds
+5. Done! Calibration is saved automatically
+
+The built-in tool performs stationarity checks and calibrates both the accelerometer and gyroscope with 100 samples each for optimal accuracy.
