TorreRotas

TorreRotas allows a group of people to create a Rotas (Dayra, 9or3a or Jem3aya); add participants to it set the turns and which person will get payments.
It will allow you to manager the Rota by accepting the members, setting the starting date, choosing who gets paid and when.
When the Rota starts it will allow you to set who has paid for each turn, and see which members the payment is missing for.
