## What is Compass Level?

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.
