calckit
20 calculators · 170+ currencies · no ads
Built for everyday math. Mortgage, interest, ROI, currency, units, tips, tax — precise answers in seconds, no account needed.
The problem
Most online calculators sit on top of an ad-driven content site. The math takes ten seconds; finding the input field takes twenty. The result feels like a side effect of the page, not the point of it.
What we built
calckit strips out everything that isn't a calculator. Twenty tools across Everyday, Finance, and Health — each on its own page, focused on one calculation, with no account, no ads, and no tracking.
- Everyday: percentage, age, date, currency, units, tip, grade, discount
- Finance: loan, savings, salary, mortgage, compound interest, ROI, tax, debt payoff, inflation
- Health: BMI, calorie, body fat
- Free, no account, no ads, no tracking
