Ive used Lygeas calculator for blackberry and this is almost as good. Only two issues are the changing of p/yr and lack of showing all your inputs at once. Mainly the first though. When you change to 1 p/yr it doesnt confirm nor give you a way of confirming the change. Then when you clear all it reverts to 12 p/yr. This should be a easy bug to fix though.
Update**after only one day of posting my review they have already fixed the bug. Now that is listening to your customer! Double clicking on display shows all the inputs too...I just hadnt noticed this feature first time around.
