Sensor update rate

GPS, compass and microphone accuracy depends on the phone hardware and environment. Do not use the app as a certified safety or surveying instrument.

GPS SPEED

  • FusedLocationProviderClient · PRIORITY_HIGH_ACCURACY
  • Sensor update rate: Fast — about 0.5 second · Balanced — about 1 second · Battery saver — about 2 seconds
  • Δd ≥ 0.5 m · σlocation ≤ 50 m · EMA α = 0.55 / 0.30 / 0.15

COMPASS

  • Android TYPE_ROTATION_VECTOR
  • SENSOR_DELAY_GAME ≈ 50 Hz · UI ≈ 15 Hz · NORMAL ≈ 5 Hz
  • True north (uses GPS correction): GeomagneticField.declination

LEVEL

  • TYPE_GRAVITY → TYPE_ACCELEROMETER
  • SENSOR_DELAY_GAME ≈ 50 Hz · UI ≈ 15 Hz · NORMAL ≈ 5 Hz
  • Level calibration: atan2 · EMA α = 0.20

01

GPS SPEED

Location is used only while the app is visible to calculate GPS speed, accuracy, true-north correction, and satellite status. No location history is created.

02

SOUND LEVEL

Microphone samples are analyzed in memory only while the sound meter is active. Raw audio is immediately discarded and is never recorded, saved, or shared.

03

COMPASS · LEVEL

Compass, gravity, and motion sensor readings stay on your device. Unit and calibration preferences are stored locally.

04

Snapshot

Snapshot images are created only when you tap Snapshot. You choose whether and where to save or share them through Android system controls.

05

Thank the developer

If you choose Thank the developer, Android opens a Stripe-hosted payment page in your browser. Stripe processes any contact and payment information under its own privacy policy; the app does not receive or store it.
