Bests & Worsts Reviews from Amazon

I like this app, easy to use, do not need to go online, which is great and is password protected, just remember to back all the way out of the app for the password to work, if I hit home in the journal, then it doesn't use the password to get back in. The one issue I have is I tend to write lengthy journals, but when I go to review my past journals, I cannot read the entire journal, not sure if I am doing something wrong or if there is a limited amount of lines that I can journal. If I try to modify an earlier journal, I still cannot get to the end of what I had written. Love to know what I am doing wrong. I'm hoping everything I input is still there, if not, rating would lose a couple stars.
