Calppy: Calculator History

A calculator that keeps your expressions. Tap any number in your history to reuse it. Big numbers, four themes, no ads, no account. There are cats. +0 is remembered too.

Not a scientific calculator. Your numbers stay readable, and the ones you just used are still there. That's all it does.

Made for everyday shopping and quick calculations. +0 is remembered too.

■ Every number stays tappable

Tap a number in your history and it goes straight into your next calculation. No copying, no remembering.

■ The whole expression stays

Calculations are kept as "1,280 × 3 = 3,840", so you can see what you actually did. Recall an expression and change just one number.

■ Built to be readable

Large numbers, large buttons. Four themes (color, mono light, mono dark, auto) for bright rooms and dark ones.

■ There are cats

One lives on the divider line. Paws appear when you tap. That's it.

■ Everything stays on your device

History is stored only on your iPhone. No account, no network, no ads, no analytics. You can copy everything out as plain text whenever you want.

■ Free & Pro

The basics are free. Calculations older than the most recent five become visible with Pro, a one-time purchase. No subscription.
