What a disappointmentBarely 5 calculations in and I gotta pay to use it??? Waste of my time, 1 star, 0 if that was possible.

Why?I wanted a calculator, not a financial commitment. The built-in iOS Calculator is free, and OpenCalc is free and open source. Please explain why basic arithmetic requires a weekly subscription.

GreedyWant a weekly payment to use a damn calculator!
