I have a Pentax K-1 and have been trying to get this app to work to transfer images over the wifi. Sometimes it does work, albeit incredibly slowly. Other times it appears to be transferring for 20 seconds or so then says the transfer was interrupted. If you've selected multiple files, you have to go back and choose them all again. Honestly, this app seems like it was designed for someone trying to transfer a single picture. Transferring more than a few at a time is a royal pain in the UI even if it does work.
Very disappointing after getting such a nice (and expensive) camera.
