Had to reload this app and was very disappointed to find ad banners that cover the bottom half of the keypad, basically rendering the Tip Calc and other apls in the AppBox useless. So my next move was to buy AppBox Pro. Oh well, the tip calc in that version is far to complicated to be useful. At least with the old version of AppBox I could punch in the info and get the totals within seconds. But no more, and with that I am done with AppBox.
