I’ve looked at several tip calculator apps and GeoTip is my favorite. ¬†You enter the total bill, tax percentage and desired tip percent and GeoTip deducts the tax from the total and calculates the tip on the total minus the tax.

The thing that sets GeoTip apart from the other Tip Calculators and makes it my pick is that it lets you save the tip and tax percentages so that you don’t have to enter them every time.

GeoTip tip: To enter a decimal point on iDEN phones press the “1” key twice.

  1. It’s impossible to run Java Applets like TextTwist from Yahoo Games on any mobile phone. There is a mobile version of TextTwist but it’s not free and isn’t available for Boost. I’ll see if there is a free game that is similar.

  2. How can i play texttwist on i290 boost? I dont knw how 2 enable java cookies in my browser?
