iOS 11 not supported

With it's abysmal slow update rate of the iOS app it was bound to happen and it did.
Rohos started with the message "Application needs to be updated for iOS ..." a few iOSes ago. Now that iOS 11 has arrived the application wont even start anymore.

Please update the application and I have one minimum feature request. Allow users to delete one item in the list instead of forcing the user to wipe the whole list en start from scratch.
