Calculator- basic + scientific
Only for Mac

Mac
Quick math without leaving the page. A calculator in your Safari toolbar - switch to scientific when you need it, or pin it to the page so it floats while you browse.
Quick Calculator puts a proper calculator one click away - no switching apps, no hunting for the system calculator, no typing sums into the search bar.
BASIC MODE
Click the toolbar button and a compact calculator pops up: digits, the four operations, percent, sign toggle and a live running result as you type. Use your keyboard if you prefer - digits, operators, Enter for equals, Backspace to correct, Esc to clear.
SCIENTIFIC MODE
One click widens the keypad for real work:
- Trigonometry: sin, cos, tan and their inverses, in degrees or radians
- Logarithms: ln, log, e^x and 10^x
- Powers and roots: x squared, x^y, square root and 1/x
- Factorials, parentheses, and the constants pi and e
STAYS OPEN WHILE YOU BROWSE
Browser normally closes a toolbar popup the moment you click the page. Turn on "Stay open on page" and Quick Calculator pins a floating panel to the page instead - drag it anywhere, keep filling in a form or reading while you calculate, and it remembers its position. Your mode and settings stay in sync between the popup and every tab.
PRIVATE BY DESIGN
Everything is calculated on your device. Quick Calculator has no accounts, no analytics and no ads - it never reads or collects anything about the pages you visit.
GETTING STARTED
After installing, open the app once, then enable the extension in Safari > Settings > Extensions and click the calculator button in the toolbar.
