Totally stopped working

I paid $9.99 for this app and it worked once. After exiting it and trying to come back to it later I had to agree again and then it tried to reload the database and it never finishes loading. I have completely quit the app and tried again, I tried restarting my phone, I made sure my iOS was up-to-date and none of it helped. I wish it would work because it was helpful the one time I got to use it.
