A smart, everyday calculator
See results as you type, edit anywhere with a tap, and keep your history within reach—everything you need, nothing you don’t.
Try free, buy once
Buy once, use forever. No subscriptions.
No ads or upsells
Clean and simple, without any distractions.

Small, works offline, and stays responsive.
Instant results & easy edits
See your answer update as you type—or tap anywhere to make a quick change. No more retyping entire expressions when you spot a mistake. Long expressions wrap so they’re always in full view.
Pin to compare
Pin a past calculation to keep it next to the current result, while you compare unit prices or perform “what if?” scenarios. Decimal places match to make it easy to spot differences.
Name your calcs
Give your calculations a label so they make sense when you come back later—rent splits, project costs, groceries, anything. Named calcs are easy to spot at a glance and ready to reuse or compare whenever you need them.
Quick percents
Just enter a percent after a plus or minus operation: 38.55+20% for tips, 189.99−15% for sales. See the exact amount in brackets as you type. The full breakdown saves to history so you can check your math anytime.
Powers & roots, when you need them
Drag the keypad up for Ans, π, 1/x, roots, and powers. Drag it back down to see more History.
Pick a theme to match your vibe
Choose from seven color themes, round or square buttons, and standard or phone-style keypads. Every theme adapts to light and dark mode and Increase Contrast, with app icons to match.
