Doesnt seem to work, no way to contact support

I just bought this app to edit the exif date for scanned photos (tiff) that I am importing into lightroom, so I can combine my analogue and digital catalogues.

Although I can change the camera name, and lighroom notices the change, lightroom does not find the changed date, which is why I bought the software in the first place.

I could find no way to contact the author for support, which is a shame, because then he might have been able to help solve this issue… There should be some kind of try before you by system in the app store for software like this with no reviews. Disapointing.
