To celebrate my calculator app PCalc turning 30 today, I've written up all the history I can still remember:
There's also a rare 30%-off sale, which runs until midnight tonight, PST.

A big thanks to everybody who has used PCalc during the last three decades!
@jamesthomson I propose a future special offer that is an IAP only accessible by entering a specific sum into PCalc.
@mo I like your thinking!
