EZ Private Notes: Protect & Keep Your Personal Notes Safe Free Version

I downloaded the app for work notes I have to keep private. Installed it and tried to open, closes out right away every time.

The app worked ok for about a year then one day I went to open it up and it does not open. I have lots of important information on the app so not a good app for me at all. I have an IPhone 6 Plus. Also lots of ads always popped up while I was attempting to log on while it was working for me.

I made a test note, set a pin number, then exited the program. Opening the program a second time worked fine. Opening a different app then going back to this app and the app has forgotten my pin. After the second try to log in it doesn't clear the log in screen. I'm wondering if the app counts 'backspace' as a keystroke. When it worked the app had a clean ui and the adds were easy to close. If the log in hadn't failed I would be happy with this free app.
