A calculator webapp without ads.

Adless Calc(ulator)

Tired of cheesy ipad apps with ads? Me, too.

Too cheap or principled to pay Apple for the privelege of letting them judge your app worthy? Me, too. (Cheap, that is.)

A beautiful solution: web-app's on the home screen! An educational experiment as well.
