Load up the app and start measuring!
Rulevelur includes:
- A ruler that can quickly switch between imperial and metric unit systems.
- One circular level and two linear levels. The movement of each bubble is constrained to +/- 10 degrees off center to make unlevel readings more apparent, but the exact pitch and roll angles are always displayed next to their respective linear level.
Rulevelur is free (as in freedom), open-source software that respects you. It does not include any ads, telemetry, or egregious app permissions.

You are encouraged to build and install the APK yourself if you cannot or do not want to pay for the app! Purchasing the app through Google Play is offered as a convenient way to get it on your device, and a way to support the project if this idea of respectful software resonates with you.
