Great news, it is released and available to everyone!
And another great news – version 1.1 is on the line getting ready – added widget and changed some texts (including title of the app). Internally refactored businesslogic placement (moved out from Activity, to allow widget to use same engine to calculate payday)
an interesting twist.. everything seems work as expected, but widget dies. At first it seemed, that only android 4.1 was affected.. but now also 6.1 has same problem. Going to investigate in near days
