Free version is terrible.

Needed quick app to level, and this is definitely not the one to use. Free version basically gives you like 5 seconds of measuring and then STOPS MEASURING and gives you a MODAL pop up reminding you it’s free. If you need to measure for more than 5 seconds, you must free up a thumb or hand to remove the pop up and continue. This was extremely frustrating and basically prevented me from doing my project.

Skip this one, get the other bubble apps. At least they are functional.

Should be called “annoying pop-up app”

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.

Great app. ENDLESS annoyances!

This app was carefully crafted to annoy every bone in your body until you upgrade to the paid version. Every couple of seconds, it disables the level and sets a 4 second countdown... then requires you to click continue to resume level use. Adds are stung all over the screen pretty much all of the time.

But... for the few seconds of use between these annoyances, it seems to be a pretty good level, and has a clean user interface.
