Everyone borrows money from time to time and this app makes it a piece of cake to keep track of all those greedy friends of yours! With the press of a button you can add a debtor or creditors from your contacts or by typing in a name, select a due date a bam! Keep Tabs "puts it on my tab" (Great Tagline btw). Instantly the total amount I owe or am owed is updated in the top left corner and I can sort the list of debts in a huge variety of different ways (first/last name, increasing/decreasing amount, date due/added). You can even add in little notes about the debt too so you keep track of what its for. Great app, its worth every penny (all 99, lol). It may actually save you money in the long run!
