Simple online tools for everyday tasks
Utility Hub collects small, focused tools that do one job well. Time a workout, a meeting, or a study session with our countdown timer, and work out percentages, tips, discounts, sales tax, and fractions with our calculators. Unit converters are planned.

How Utility Hub works
Works in your browser
Tools run on your device. There is nothing to install, and the timer and calculators don't send what you enter to a server.
No account needed
Open a tool and use it straight away. No sign-up, email address, or login.
Built for every screen
Layouts adapt to phones, tablets, and desktops, and every control can be used with a keyboard or screen reader.
