Pocket Bubble Level XXL is an accurate, nice, and easy-to-use application that is perfect for every handyman, DIY enthusiast, and smartphone holder. This iOS app uses your smartphone's accelerometer and gyroscope (depending on the model) to help align and level objects horizontally, vertically, or at any angle. The app displays the inclination angle in each plane, like a laser level, and allows you to lock the orientation. Additionally, you can measure the angle or slope of any object, such as a roof pitch, table, wall, and more.

The app's display and indicators are easy to read, and it doesn't require an internet connection. Moreover, Pocket Bubble Level XXL has premium features, such as no ads, a bubble level 3in1, a clinometer for measuring vertical angles by aiming, and the ability to change a reference system. The data is presented in degrees and percentages, and the app is powered by the camera, resulting in an augmented reality-like spirit level.
