I have had this app on my phone(s) for several years. I didn't use it that often but has been useful in a pinch. I just used it again after some time and a couple updates. Had to wade through a bunch of garbage and some permissions before I could use the app again. Why would something so simple need access to my location? It's a bubble level not GPS maping software. To top it all off there is now audio included! Like I need a bell to ring when I have something level. Should have kept it simple.

This app sucks. Orientation lock on or off, when you get to around 43 degrees it changes orientation and screws up your reading

Extremely Accurate . I had just moved into a new house and had no idea where my tools were. I was setting up a 125 gallon fish tank and had to make sure that the tank was level. Bubble Level saved the day. Also helped when I was hanging curtain rods. I highly recommend if you do not have or cant find your tool box and level. Just download the app and BOOM, instant Level!
