Is something tilted?

 

　This App will answer such a question easily and quickly. However there are some level gage Apps, these Apps need to touch the things which you want to check and these Apps can not check the things far from the device.

 This App shows a virtual vertical grid wall in front of the iPhone camera, then this vertical wall is very helpful to check whether the something is vertical. There are no needs to touch the device to the thing, and this App can check the things far from the device.
