Compass Level: Sensor Toolbox

Compass Kit puts four everyday sensor tools in one fast, clean app, using the sensors already built into your iPhone or iPad. COMPASS • Live heading with cardinal direction and degrees • True North using automatic magnetic declination for your location • Stability and magnetic disturbance indicators, so you know when to trust the reading LEVEL • Plane mode shows tilt on both the X and Y axes • Single-axis mode for quick one-direction checks • Zero the reading on any surface, with optional haptic feedback ALTIMETER • Combines GPS altitude with the built-in barometer on supported devices • Shows relative altitude against a reference you set • Shows the data source and a confidence level, so you can see what the number is based on • Metric or imperial altitude units MAGNETOMETER • Live X, Y and Z field strength in microtesla • Interference level indicator • Optional location tag on saved records SNAPSHOTS • Save a reading from any tool with the time and, if you allow it, a location tag • Filter by tool or by location tag • Export as JSON or share with other apps DESIGNED TO STAY OUT OF YOUR WAY • Dark "Night Radar" theme and a light theme • Available in 13 languages • No account and no ads • Location is used only while the app is open, and only when you allow it • Readings are processed on your device Good to know • Barometer and magnetometer features need hardware that not every device has. If a sensor is missing, the app tells you and explains what is still available. • Compass and magnetometer readings can be affected by nearby metal, magnets and electronics. • Altitude from GPS and barometer is an estimate. Compass Kit is a convenience tool and is not intended for aviation, navigation safety, surveying or professional measurement.
