Really sorry it wont open
Four people in this family downloaded this app into some of the most up-to-date Apple iDevices and on all of them it behaved the same: the app failed to open. It is a great idea, but there must be a bug in this version because even rebooting the devices and deleting and reinstalling the app fails to change the behaviour: it tries to open and then fails back to the home screen. Sorry. Will update this post if it gets fixed.
