Past few versions of this app have been hogging large amounts of battery power on my iPhone. Also, latest version has a bug with the Resume Puzzle feature. When you open the app and click to Resume a puzzle, the bottom of the puzzle above the keyboard will be cut off, because the puzzle opened under the notification bar at the top of the phone. Normally the puzzles open over the notification bar so that the elite grid is visible.
