I understand the developer stopped development and support of the application a couple of years ago.
If you have the application already installed on an old device you can use an AppBackup application available on GPS to legally create a personal backup APK file-
This APK file can then be installed on any device.
I am not sure where we stand on sharing the APK as it was a paid application - there were free version - but with lesser functions
does any one know where we stand on this from a Copyright infringement perspective ?
