About this app

MotionRecord turns your Android smartphone into a precise measuring instrument. The app records sensor data at up to 100 Hz and stores it as analyzable JSON files — no cloud, no account.

NEW: COCKPITS & RECORDING
• Six cockpits, starting in Fullscreen Lean: large lean angle, speed and corner counter at a glance
• "Explore the cockpits": try every view with a live preview and apply it with one tap
• Running recording on the lock screen with recording time, live values and stop
• Library with compact list, multi-select and a trash (30 days)
• Open directly in Kurvenfokus and analyse your corners

SENSORS
• Accelerometer (3-axis, in g)
• Gyroscope (3-axis, rad/s)
• Magnetometer (3-axis, µT)
• GPS (position, speed, altitude, accuracy)
• Barometer (air pressure, relative altitude)
• Rotation vector (quaternion, Euler angles)
• Gravity & linear acceleration

SIGNAL PROCESSING
• Real-time filtering: low-pass, high-pass, moving average
• Butterworth filter (IIR, 4th order)
• Jerk calculation (rate of change of acceleration)
• Frequency band separation (low/mid/high)
• Calibration (bias, drift, noise floor)

RECORDING PROFILES
• Walking/running: 100 Hz IMU, 1 Hz GPS
• Motorcycle: 100 Hz IMU, tuned filters
• Car: 50 Hz IMU, stronger smoothing

FEATURES
• Background recording, also with the screen locked
• Chunk-based storage (no memory overflow on long sessions)
• Export as JSON (iOS-compatible), GPX and CSV
• Library with all recordings, map and traces
• Recording works offline — map tiles and place names load when you are online

PRIVACY
All data stays on your device. No analytics, no ads, no tracking. You decide when and with whom you share your data.
