A full version app for Android, by Mustafa Alpay.

AR for Minecraft: Augmented Reality for MCPE is a handy tool that allows you to view and interact with your Minecraft worlds in the real world. It’s not a game or an app in itself, but it can be used as a companion for Minecraft Pocket Edition. The app can be used to see your Minecraft world in the real world, as well as your surroundings. The camera can be moved around, zoomed in and out, and the image can be rotated and scaled. The image is also mirrored, so you can view the opposite side of the image.

It’s compatible with the latest version of MCPE, but it’s not guaranteed to work with all devices.
