If you're remodeling a room or want to determine the dimensions of a space in your home before purchasing furniture, a measuring app for Android can save you a lot of time and headaches.

ARPlan 3D is one of the most innovative measuring apps for Android on this list. It provides you with an augmented reality measuring tool for measuring the dimensions of a room.

First, measure the height of the wall, then measure the perimeter of the floor. The app converts those measurements into a full 3D model of the room, which you can save as a PDF, JPG, or DXF file.

Bubble level is one of the simplest apps of all. It works like a regular level you would buy at the hardware store, but it is three levels in one. At the bottom of the screen, the x and y coordinates are displayed if the level is even slightly off center.
