Theres an app on the windows marketplace for phones called spendtracker I've seen before. It was kinda neat. It allowed you to seperate expenses into different categories upon weeks/months/years.
The problem is I can't find a program like it on windows 7 PC.
I've tried you need a budget on steam, but that is fairly limited compared to this program and it does not do weekly which is something I need.
I've tried googling similar apps/programs but it just comes up with spentracker for the win8 phone everywhere.
