I have just purchased this app for my iPhone and am quite pleased with it.

One thing I would prefer to see is, to be able to input an amount directly, not as a percentage.

So Total = 90.00

Category 1 = 23.00
Category 2 = 27.00
Category 3 = 16.00
Category 4 = 24.00

or Total = 36.18

Category 1 ...
