In iOS7 the keypad does not come up when the app is launched making this app useless. I did find that after a hard shutdown and restart of my iPhone 4S, the app will work one time only, which allowed me to synch with my Mac and see passwords. Once you quit the app however, it will again fail to present the keypad upon relaunch until the next hard restart.
2nd Update: the long promised update for iOS 7 is finally here. Solves the launch issue, but now when I tap on a hidden field, it does not appear. Have to go into edit mode to see hidden security questions, etc.
Update: received the following in response to my email to iAccounts:
"We plan to post the update to Apple for review this weekend or early next week, in the meantime please use this easy fix: quit the app from the iPhone app switcher (bring up the apps running in background and quit iAccount by swiping upwards on its snapshot screen) and relaunch it to bring the keyboard up, no need to restart your iPhone. Update coming soon, apologies for the inconvenience, in the meantime you may consider switching to an A-Z password, which is not affected."
