What's New
Version 2.19 Fixed bug when user enters too many digits
Version 2.21 changes the way the app remembers keyboard layout. There should be no visible change, but it will prevent bugs in the future when layouts change.
Version 2.20 died with a "class not found" error. Probably a compilation problem. Users who installed 2.20 should immediately install 2.21
