Bubble Level Plus+

I’ve used many of the level apps and they are either too hard to read or they are inaccurate. This is the best so far.

It’s a very nice app for leveling with one glitch— it always moves from vertical to horizontal to even when you don’t want it to. Sometimes I’m trying to measure an angle where there’s not enough room to place the phone lengthwise, so I set to measure vertically but it quickly resets itself and takes away my measurement. Other than that the app is very nice.

I downloaded this app based on the number of reviews when compared to other similar apps. Does it measure an angle? Yes, but you get an annoying pop-up every few seconds telling you that your measure time has run out and you either need to wait 5 seconds to clear the pop-up, only for it to return a few seconds later, or upgrade and pay for a version without it. I suppose if you need a single measurement that can be done quickly before the pop-up occurs, then this app may work for you and be less annoying. But if you need to take precise measurements and multiple measurements, there are several other apps that can accomplish this and did not have the annoying pop-ups. Perhaps at some point, this app didn’t have the annoying pop-up. As it gained popularity, I imagine the developer probably added in hopes to earn extra money.
