LineEmUp

The LineEmUp app can be used to line up anything.  You can chose a fixed alignment sight line, or a floating sight line with or without a level line.  A sight line and date embossed picture can be taken by this app to prove the alignment.  LineEmUp allows you to use the camera zoom for best accuracy.
