Hours And Minutes Calculator

Easily add and subtract hours and minutes

Add and subtract hours and minutes the easy way — 8:15 + 7:45 = 16:00 — and get the right answer every time.

Hours & Minutes Calculator does the time math your phone's calculator can't, right in H:MM. Total a week of shifts, subtract a lunch break, turn hours into pay, and hand off a clean timesheet — free, private, and offline.

REBUILT FROM THE GROUND UP This is a complete, ground-up rebuild of the app trusted by users since 2015. The math is fixed, the old limits are gone, and every feature is free. If you add up time for timesheets, billable hours, work shifts, payroll, or projects, this is the calculator you can trust.

WHAT YOU CAN DO

• Add and subtract time in hours and minutes (H:MM), chaining as many entries as you need: 8:15 + 7:45 − 0:30 and so on.

• Multiply and divide a duration by a number: 1:30 × 3 = 4:30, or 3:00 ÷ 2 = 1:30 — perfect for splitting or scaling hours.

• Turn hours into pay with an hourly rate: 8:30 at $20/hr = $170.00.

• Switch between H:MM and decimal hours with one tap (1:30 ↔ 1.5) — ideal for payroll and invoices.

• Handle overnight shifts and negatives with ease: 23:30 + 2:00 = 25:30, and 1:00 − 3:00 = −2:00.

• No caps — total as many hours as your week actually holds.

• Modern backspace: before you hit "=", edit the whole running expression digit by digit, just like your phone's built-in calculator.

KEEP AND SHARE YOUR WORK

• Save your calculations to a history you can reuse and search. • Export your history or timesheet to CSV and PDF, straight to the share sheet. • Copy any result with one tap.

MADE TO FEEL RIGHT

• Clean, familiar calculator-style layout — nothing to learn.

• Dark mode and light mode, with custom accent colors.

• Haptic feedback on every tap.

• Fully offline and fast. Your numbers stay on your device.

EVERYTHING IS FREE No subscription. No in-app purchases. No "Pro" tier. No ads. No account or sign-in. And no tracking or data collection — your calculations stay on your device. That's not a limited version; it's the whole app.
