CompassTally

Turn your phone into a precise digital compass and bearing finder — fully offline, with no account, no ads and no location permission.

LIVE COMPASS
• A rotating compass rose reads your live heading from the device's rotation-vector sensor (with an automatic magnetometer + accelerometer fallback), smoothed for a steady, accurate readout
• A large numeric heading in degrees plus the 16-point cardinal label (N, NNE, NE, ENE, E... all the way around)
• Switch instantly between Magnetic north (straight from the sensor) and True north (corrected with your own manual declination offset)

TRUE VS MAGNETIC NORTH
• Enter your local magnetic declination once and CompassTally applies it correctly in both directions
• No location permission required — CompassTally never asks where you are; you look up and enter the offset yourself
• A clear declination summary is always visible on the Compass tab

BEARING & WAYPOINT TOOL
• Enter any target bearing in degrees
• A turn-by-turn "turn left" / "turn right" indicator, plus a bar gauge, shows exactly how far off-target you are
• A highlighted marker on the compass dial points straight at your target bearing as you turn
• Clear "on target" confirmation when you're lined up

CALIBRATION HELPER
• CompassTally watches the live sensor accuracy and shows a clear "move your phone in a figure-8 to calibrate" prompt whenever accuracy drops
• A simple accuracy pill (Good / Fair / Poor / Unreliable) is always visible

LOCAL HISTORY
• Save a labeled heading or bearing reading — "trailhead direction," "property line," anything you like
• Review or delete saved readings any time
