Tipper2.0 has been submitted to the App Store, we’re just waiting for approval. 
Tipper2.0 is a complete rewrite and redesign of the simple tip calculator! This new version features a new clean interface based off of a “Guest Check” and has support for international currency symbols based off your Region Format setting.
This new version also features a custom number pad with buttons for clearing the bill amount, and stepping back one number. The sliders have been replaced with two pickers, one for the number of people to split the bill between and another picker for the tip percentage.
Tipper maintains its simplicity by only having two input views, the number pad and the tip/people pickers allowing you to quickly and painlessly calculate what you owe.
