Something is wrong. Help!

I have enjoyed using this app for quite some tome. But since I upgraded to the newest version of IOS, this app no longer works properly. When I try to log an activity, I can select the activity, but cannot select time, date etc. The app freezes and I cannot even cancel out. I have uninstalled and reinstalled, shut down and restarted with no improvement. Help!
