Utilities

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.

Excellent app

I used it for Astronomy for rough location of sky objects (AZI and Alt). Getting both Direction and angle tilt up to 90 deg in one simple app like this was great news for me. It will be good if the device gives both readings for magnetic and true north on same screen. Now I’m updating my review after using it with Apple Watch. I’m very impressed with the functionality of reading the phone direction and level on the Watch. Your application is real piece of art and second to non in this area.

This app has a clean and simple UI. Additionally, the app serves its functional purpose superbly by providing precise measurements through an easy to read and straightforward interface. Making any changes to the settings is self explanatory. I can’t say much more regarding the efficacy and efficiency of this app as a whole. So KUDOS to you, Mr. Develper, on a job well done!!

After searching through a bunch of subscription based apps this is a refreshing break and works perfectly, both the level and the compass

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.
