Bubble Level XL vs Bubble Level + Compass使用状況と統計

A bubble/spirit level tool with horizontal, vertical and surface angle measurements, as well as a true-north compass. Advanced features are included, such as calibration for the surface level to work with your phone's case/camera bulge etc. No full-screen ads or nagging popups! The tool is normally included in my astronomical app (Polar Scope Align Pro) where it has some extra functionality (night mode, watch version), but I decided to release it as a separate free app because I could not find anything with the features I wanted on the app store. If you enjoy it, feel free to leave a review. There is also an ad-free Pro version with more features like Apple Watch support, night mode", pitch/yaw/roll rotation rate. Basic Features: -Bull's eye level with surface angle reading, horizontal/vertical levels with angle readings (0.1 degree steps). -Compass with north heading reading in direction and degrees. -Works on iOS 11.0 or higher. Extra features: -Magnetic declination reading, which shows the offset between magnetic and true north for when you want to use a physical magnetic compass (requires access to your location). -Accelerometer/Gyro switch in case one of the two works better on your phone (Gyro is default). -Magnetometer (compass) calibration level display. -Gyro calibration to compensate for lens bulges or uneven cases when using the phone as a bubble/spirit level.
