Bubble Level + Compass Pro combines a precise spirit level, compass, and Apple Watch companion app, so when your phone is placed somewhere hard to see its screen, you can still get live readings from your wrist. No more out-of-reach setups, and no more crouching. Features: • Bullseye level plus horizontal and vertical levels with 0.1 degree precision • Bubble level units: Angle (degrees) or Incline/Slope (%) • True and magnetic heading with direction text • Magnetic declination • Apple Watch companion app • Gyro or accelerometer sensor mode • Gyro calibration offset to compensate for camera bulge or uneven phone cases • Pitch/Roll/Yaw rotation rate readouts • Compass calibration status • Red-light night mode The tool is normally included in my astronomical app (Polar Scope Align Pro), but I decided to release it as a separate app because I could not find anything with the features I wanted on the app store. (A free ad-supported version is also available)
