Beschreibung

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.

Version 1.9

Remember, the app tries to be nice and never nags you with popups (I hate those), so it gets very few ratings/reviews. Support it by rating it!
What's new:
- Improved help with Table Of Contents.

Strange behavior

If I align to north and rotate the phone precisely 180 degree the needle deviates 9 degree.
If I use two phones and align them, they also differ. HWplease

The digital compass in a phone is not very accurate, as it is easily affected by local magnetic fields. If you are doing big movements with your arms holding your phone (see the help screen, "figure 8" movements are suggested) before each measurement and avoid placing the phone near metal/magnets, you should expect an accuracy of about +/- 2 degrees or so. At least that's what most users get with various iPhones - although from model to model they can be better or worse.
If you are consistently getting worse performance, make sure you don't have something like a magnetic clasp case etc. In any case, there's nothing "magic" an app can do to fix this, it is a hardware limitation of all phones.
