Although a level is a basic tool, I hadn’t considered releasing one for a long time. That’s because I had already released a protractor app with similar features.
It wasn’t until five years later that I received feedback pointing out that when users want to level a picture frame, they search for a “level,” not a “protractor”—so I rushed to release it.

Go to Settings and turn on the [Alarm] option. A speaker icon will appear at the top of the home screen. You can use this to turn the sound on or off.
※ Orientation sensor ??
Most level apps rely solely on the accelerometer. However, this sensor has its limitations. If the incline exceeds 60 degrees, the readings become highly inaccurate. In other words, while it’s great for leveling, it’s not ideal for measuring slopes like those found on inclines.
This level app uses the compass sensor to provide a solution. By adding the compass sensor, slope measurements become very accurate. We recommend keeping this option turned on. If your device lacks a compass sensor or the ball does not move smoothly, please turn this option off.
※ FAQ
