Useless with iOS 10 - dont buy

I upgraded to iOS 10 and ever since, the diary does not work. It crashes every single time upon opening it. The appa creator has a website but no contact information on it.

I am seriously considering asking Apple for a refund, since this app, one I paid for, no longer works.
