Worst App ever

I had to reset my phone backed up all my apps on my Mac including another hidden folder app, however this one would not allow me to open the folder anymore despite writing the correct passwords. I tried at numerous occasions and it says password incorrect!!! had pics and videos saved for memory and lost them all, I can clearly see the count of pics and videos but once I open the app nothing appears. Everything is gone, very disappointed, if I knew I would have never gotten this app. Pls fix before as I refuse to delete the app and loose all my data?!!
