Bubble Level + Compass Pro vs SynScanLink使用状況と統計

A bubble/spirit level tool, with both a bull's eye level and horizontal/vertical levels, as well as a compass (showing both true/geographic and magnetic north), and support for the Apple Watch. Watch support allows you for example to set your iPhone on the top of a tripod, and work on leveling its legs by looking at your watch - without having to go through the stand-up-to-look-level/crouch-to-adjust-leg routine. 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. You can try the free ad-supported version that lacks the Watch support. Basic Features: -Bull's eye level with surface angle reading, horizontal/vertical levels with angle readings (0.1 degree steps). -Compass with true/geographic north and magnetic north heading readings in degrees and direction. Extra features: -Apple Watch support. -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). -Gyro calibration to compensate for lens bulges or uneven cases when using the phone as a bubble/spirit level. -Gyro rotation rate function: measure instantaneous or cumulative rotation on 3 axes (pitch/yaw/roll). -Magnetometer (compass) calibration level display. -Red-color night mode to preserve night vision.
