This application lets you know how many days are left in the current month until you get your SU.
It also has an intuitive Widget. With it, it is easy to see when SU is paid out, so you have time to prepare for it.
The Danish government pays a monthly allowance (SU) to students in order to support their studying (mostly to Danish students, but also foreign students fulfilling specific conditions). This allowance is paid out on the last business day of every month.
The app shows the remaining number of days until "payday". It came from a little personal frustration that I had every time I had to look in the calendar and spend some time figuring out when is the last business day of the month. And I did not want to add a calendar event for it, as I already have my calendar full - and Id have to do that manually for every month.
