Crashes after iOS 9 update

Normally a 5 star app, but it keeps crashing since iOS 9 update. Please fix!

Update: THANK YOU for listening on the need for multi-tasking autolock for info information protection. 5 stars now!

I use this app daily for sensitive info. It should AUTOLOCK every time I leave the app. Now, I have to double click home button and find the app to ensure it closed. Otherwise, app is still open and info is vulnerable to view without re-inserting password. Pls update! Thks.
