it works on my car with BT on a mac but doesn't work with iPhone

Hi

I' ve made the overlay
The overlay ran up to 100% (3500 pictures)
The app wrote "transfer to photo library" and the stop
There is no film in iphone library

the picture of preview under the track time is still there and i can make an overlay again ... with the same result.

What am I doing ...
