Whenever I have an app idea, I first check tinder if there is already an existing app. This looks like just what I thought of, so I downloaded it. But… when I use the camera to take a picture of the position sheet, it never worked. First, it took a long time while I held very still, or moved in closer or farther away. The scanning area is landscape, but position sheets tend to be portrait…. Wasn’t sure which was the correct orientation. Anyway, never got it to take a picture of the sheet. Would be nice if there was a manual override…. Hopefully the bug will be fixed and I can try again.
