"Flatten the slope out"

Reviewed by / Jun 09, 2011

Bubble is an app that turns your Android into a bubble level

It's just mad how the apps are emptying our toolbox by adding new functionalities to our Android devices. In this case, you won't have to worry anymore if you are refurbishing your home: here comes Bubble, a virtual bubble level as accurate as the physical ones.

Calibrate each side of the phone independently to achieve total accuracy. It will show the numeric angle of the slope or will speak it out loud. When you reach the flat level (or the slope level you aim) it warn you by flashing the light, beeping or buzzing. In order to lock the angle you want to, you just need tap on the screen. That easy.

Bubble has been developed by Ben Zibble, an individual developer who has launched some apps on market with no an specific issue but with the aim to become tools that make users' life easier.

Bubble is one of those app that you won't use everyday, but you'll really appreciate to have it installed in your device. It provides a double advantage: you'll save some money by not to buying the physical bubble level and allows you to set angles and extra-features that you don't even can performance with the pysical bubble level. Reliable.

    Small, simple, accurate (enough). What more could you want?
