1. Useless! Tried using to install a TV mount and could clearly see what the app level said was level and true was it about a 1/4 of an inch over an 8" piece! I know it's an app but if it can't get closer than that it is useless like I said!This level has been great an it is accurate just have to remember if you have buttons on the side of your phone case to use the other side other than that highly recommend it simple and easyIt is great it's absolute 100% what I've been wanting I appreciate it but I believe it is an or I hope it is a free app I'm a marine on a very tight budget it must be free or I cannot have it thank you❗️😎This a application that dose what it says it dose.
2. The app has everything i need.About everything I've been looking for in a bubble level app! Request - In the paid version add the button to select % slope to the main bubble level screensIt is a very good device period can carry level around in my pocket.
3. not using a phone case while trying to level, using an LG Stylo 4.Got the paid version, money well spent.
4. The buttons will distort the balance which will make it pointless.it works as an app, but doesn't seem 100% accurate.
5. Just remember to place your phone on the whichever side has no buttons.
6. Do not have to look for itThe app is very functional with straight forward operation.IMHO, the best balance of features, function and simplicity.
