About this app

A bubble level, a spirit level, or a plumb bob is a tool used to check whether a surface is horizontal (level) or vertical (plumb). The Bubble Level Tool, Leveler app, also serves as a goniometer or a carpenter’s level, can be applied in construction, carpentry, photography as well as daily life. It mimics and works like a real level meter. It is very handy and useful to provide you with accurate results.

Where you need Bubble Level:
🖼 At home: Use the Bubble Level to perfectly calibrate and position the object if you need to hang a picture or a photo frame onto the wall, or assemble a shelf, a refrigerator or a washing machine.
🏗️ At work: This level tool is a must have app for horizontal and vertical calibration in fields such as construction and carpentry.
📸 In photography: It is a good helper if you want to set up a tripod.
🏕️ Outdoors: Don’t you think a tilted camping car or picnic table is annoying? The Bubble Level can help you place it horizontally.
🏓 Other situations: When you are leveling a billiard table or a table tennis table, or inserting a shelf, just grab your phone and use the app!

How to use the Bubble Level:
The Bubble Level also simulates a bull’s eye level, which levels across a plane. To determine whether a surface is horizontal or vertical, or to measure its inclination angle, you can simply lay your phone flat on the surface, or lean the phone against it.

This leveler app indicates horizontal when the bubble is in the middle. It will show the actual angle in the meantime. Thanks to its sound effects, you can hear the result without looking at the screen.

Ratings and reviews

I installed this to replace another level app which had tried to go very fancy. I love the graphic display on this, but the bubble displays are not sensitive enough. There needs to be more movement of the bubble for small angle errors, and the inner guidelines on the tubes need to be the same distance apart as the length of the bubble. If these things were fixed I'd happily pay to go ad-free.

Shows the ad full screen without the options to hide/remove it. No idea how to continue. "Back" button didn't work, re-launch works sometimes. Will uninstall as soon as I can. I discovered the button to remove the ad: it is at the top-right and not displayed all the time. I would prefer something user-friendly, like, a shutter to slide vertically.

I have a bookshelf I built to calibrate levels on, and this one is perfect on my phone. There are ads, but only a little irritating (I was going to say not irritating, but then I saw a full screen one pop up). You can click the button top right to go to the app, or just pay the $3 for the app, which is cheaper than the level I keep forgetting to get out of my toolbox. Developers deserve to get paid.
