1. phone small enough for the sides my other regular level wouldn't work.
2. I love to review all types of things, and ONLY as I see them!! 🇺🇸Just discovered this app, and immediately deleted the previous bubble level app I have been using.
3. Woodwork is one of my hobbies and I regularly want to check for level in two directions, or make something to a particular angle, eg a ramp toy.
4. Just open and use.As long as your phone accelerometer is good, this app works excellently, with a pleasant design and easy use.
5. Important: Lay phone on a table and tap the + icon to zero the angle display.
6. However, it does require a very level surface when calibrating.
7. Right as this app was finished installing , I opened it and was using the level within a couple seconds.
8. This is done by placing the device ( in my case a smartphone) on a level floor to teach the program what perfectly level is.
9. and the bottom sprayer is so it's flat so for something like that this is a perfect level probably not too much for anything of length.
10. Adding the ability to average two calibration runs, with the phone rotated by 180 degrees between each run, could improve this.
11. Bubbles give a clear view of exact level state.
