Password no longer works

I was very happy with this app until my old phones screen broke and I had to replace it. Now, whenever I try to get into it, it says I have the wrong password when I know I remember the password I was using before. I see many other people in the reviews are having the same problem and would like to see it fixed so that I can actually use this app, which I paid $5 for.
