Fixed! Last update broke it I was really enjoying this app  but after the last update it crashes whenever I try to exit from a puzzle and return to the page with the puzzle list. All progress on the puzzle is lost in the crash. I also dislike the new white keyboard. If the crashes are not fixed I will have to uninstall. UPDATE: The crashes seem to be fixed  so I'm giving it 4 stars. Will be 5 when there is an option for a dark keyboard. This is a really nice app.
