Calculator
A fast everyday calculator with a keypad sized for one-handed use and a running tape of every step.
Built around the way people actually calculate on a phone: big targets, instant response, and history you can scroll back through instead of retyping. The arithmetic engine keeps full precision internally and only rounds at display time, so long chains of operations do not drift.
