KEY FEATURES
● Calculate as you type: tap "=" after any expression and the answer appears inline; long-press "=" to keep just the result
● Percent math the way you think: 4500 - 15% gives the discounted amount instantly
● History inside the keyboard: tap to re-insert a previous result or the whole expression; clearing always asks for confirmation
● Customizable toolbar: clear, cursor keys, forward delete, dismiss keyboard. Add, remove, and reorder freely, or create one-tap custom text keys
● Rearrangeable keys: swap the operator column and function keys; the spare key slot can be ( ), 00, 0.00 and more
● f(x) panel for advanced functions: √, x², x^y, sin/cos/tan, ln, log, π and more
● Every calculation rule is a setting: 0–8 decimal places, rounding mode, thousands separators, implicit multiplication, auto-closing parentheses, operator spacing
● Home Screen widget: calculate on your Home Screen (iOS 17+), sharing the keyboard's settings
● Make it yours: light and dark themes that follow the system, 8 accent colors, and your choice of a black or white app icon
● Localized in English, Traditional Chinese, Japanese, and Simplified Chinese
PRIVACY: WE CAN'T SEE WHAT YOU TYPE
SumKey never asks for Full Access. That is a system-level guarantee: we cannot see, store, or upload anything you type. The keyboard cannot connect to the internet, contains no analytics or tracking, and works fully offline. Your calculation history stays on your device only.
