YoCalculator
A calculator that gets the maths right — and remembers what you did.
Built for the way people actually calculate
Correct by default
Full operator precedence and exact decimal arithmetic — no floating-point surprises when money is involved.
Percentages that make sense
200 + 10% = 220 — percentages read from context, the way you'd work them out on paper.
History you can reuse
Newest first. Tap any result to drop it back into a calculation, delete a single entry, or clear the lot. Keeps your last 200.
Chain without stopping
Keep going from the last result, back out a digit at a time, or clear and start fresh.
Set it up your way
System, light, or dark theme. Zero to eight decimal places. History on or off. Your language and number formatting region.
Stays on your phone
No account and no server. Your calculations and history stay on your phone.
Android and iOS
One shared engine
The arithmetic, history, and settings are shared Kotlin Multiplatform code, so both platforms give identical answers.
Native where it counts
Storage uses each platform's own mechanism, and the interface follows the conventions of the phone it's running on.
