Money Tab ($0.99)

If you're broke, spending 99 cents on an app that doesn't let you smash zombies to smithereens to vent some anger might not sound wise. But this budget-tracking app has such a clean, simple UI that it might mean you won't find yourself in this situation again. You can view your spending in pounds, of course, and add recurring transactions for the big stuff.
