Calculate
Read full descriptionHide full description
Calculate is a clean, considered calculator built for the moments when accuracy actually matters — quotes, budgets, splitting costs, or just double-checking a big number. NEVER RETYPE A NUMBER Every calculation is saved to your history. Tap any number from a past result to reuse it instantly in your next calculation — no more retyping long figures and risking a costly typo. CUSTOM MULTIPLIER SHORTCUT Long press the % button to set your own multiplier — perfect for adding taxes, applying a margin, or working out a discount, all with a single tap. CURRENCY MODE Press $ to round to two decimal places and format as currency, exactly how you'd write it. LOCK AND PIN WHAT MATTERS Swipe to lock a calculation so it never gets deleted. Pin your most important figures to keep them always within reach at the bottom of your history. BUILT TO FEEL RIGHT Satisfying haptic feedback on every key press, a refined near-black and brass design, and a calculator that feels like a quality tool — not a toy. Simple. Considered. Built for how you actually think through numbers.
