A bubble/spirit level tool, with both a bull's eye level and horizontal/vertical levels, as well as a simple compass 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 North heading reading in direction and degrees.

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).
-Gyroscope calibration.
-Magnetometer (compass) calibration level display.
-Red-color night mode.

What’s New

Version 1.7

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:
- Gyroscope calibration added in the settings.
- Non-retina option for watch graphics to increase the refresh rate.
- A small rename of the app to keep it consistent with the free version.

Nice clean interface

This does just what it says and does it well. Very responsive and accurate. Used the free version for a bit but wanted to support the developer directly.

Just what I needed

Definitely worth a dollar. The Apple Watch displays the sensor on the phone which is actually what I need.
