I've read from time-to-time that people are using their smartphone as a wireless remote for the A7. I've loaded the Memories app and all I can seem to get it to do is want to upload pictures from my camera to my phone. Something I have no interest in doing. What I do want to do is use the iPhone for a wireless remote, preferably with live view. I can do it with Fuji XT-1 and its useful. Can someone point me to clear description of what app(s) to load on phone and how to get the interaction with camera reliably established so it can be reestablished without having to start from scratch. Thanks.
