Quick answer
Align your phone with a previously taken photo
This app creates a semitransparent overlay of a picture on top of the phone's camera preview. This allows the phone to be positioned in the same location and orientation as when the original picture was taken.
Currently I use this app as a quick way to align the antennas for my software defined radios with a fixed point, but there can be other uses as well.
This app also has the capability to select a certain color to be transparent for "green screen" style overlays. The transparency can be applied to the image or the live camera preview.
This app has no ads or in-app purchases and collects no data.
Source code is available on GitHub: JS-HobbySoft/CameraAlign
