Having just started my membership trial, I put 1password7 on my new iPhone. It's gone now!!
It is just too difficult to log in and use it. Long master password to be entered on a small touch screen plus the inconvenience of using it in an ios browser compared to OS X lead to me deciding to ditch it. I can manage it on the larger screens of an iPad but not on the iPhone.
It's a shame but life is too short to put up with the level of frustration it was giving me!
