ClockTools FAQ
Is ClockTools free?
Is ClockTools free?
Yes. Our current tools are free to use, from clocks, timers and calculators to network checks, developer utilities, music tools and browser games. You do not need a subscription to use the features available on our tool pages. Your internet provider's normal data charges still apply when a task uses your connection.
Do I need an account to use ClockTools?
Do I need an account to use ClockTools?
No. You can use our tools without signing up or creating an account. Some tasks still need your input: choose a countdown date, enter text to convert, or allow location access when you use a GPS tool. Where a tool saves settings or history in your browser, that data does not automatically follow you to another device.
Can I install ClockTools as an app?
Can I install ClockTools as an app?
Yes, where your browser supports it. Look for Install app or Add to Home Screen in the browser menu to keep ClockTools within easy reach. Installation is optional: you can also open every tool directly in your browser. An installed shortcut does not turn our browser alarms into a background alarm service or make every feature available offline.
Does ClockTools work on mobile?
Does ClockTools work on mobile?
Most of our tools work on phones, tablets and computers, with layouts that adapt to the screen. The best device depends on the task: our typing test is best with a physical keyboard, while GPS tools need location support and permission. Browser features such as notifications, fullscreen and keeping the screen awake can also vary by device.
Do alarms and timers work if the browser is closed?
Do alarms and timers work if the browser is closed?
No. Our browser alarms and timers cannot alert you after their page or browser is closed. Saving an alarm preserves its settings, not a running background service. Keep the page open and the device awake, enable sound and test the alert first. Browser suspension or power-saving settings can still interfere, so use your device's built-in alarm for essential reminders.
Can I share tool setups?
Can I share tool setups?
Yes, on tools that offer a Share control. A link can carry supported settings, such as an alarm time, timer duration or countdown date, so someone else can reopen that setup. It does not remotely start another person's device or synchronize a live session. Check dates and time zones after opening a shared link, and keep sensitive details out of names or labels included in the URL.
Is ClockTools only for clock and timer tools?
Is ClockTools only for clock and timer tools?
No. ClockTools began with time, but our collection now includes typing tests, calculators, printable calendars, location tools, network diagnostics, text and developer utilities, music tools, randomizers and browser games. Use the homepage search or the categorized All Tools directory to find what you need. We continue improving existing tools as well as adding useful new ones.
How accurate are the results?
How accurate are the results?
It depends on what a tool measures or calculates. Calculators follow defined rules, but their results still depend on your inputs and the stated assumptions. GPS speed, connection tests and service-status checks depend on device readings or information available at the time. We explain relevant units, checks and limitations below each tool. Cross-check important results with an appropriate reference rather than treating every displayed number as a certified measurement.
Why do some tools ask for browser permissions?
Why do some tools ask for browser permissions?
A feature may need permission to do its job. For example, finding your current location needs location access, and browser notifications need notification permission where supported. These requests belong to the feature you choose to use; you do not need to grant them just to browse ClockTools. If access is blocked, check both browser and device settings, or use a manual alternative where the tool provides one.
Does ClockTools work offline?
Does ClockTools work offline?
Not every feature does. Website checks, live service status, IP lookups and internet speed tests need an internet connection. An already-open tool may continue a local task, but reopening pages offline is not guaranteed. Our small play area can work offline after a complete first download if browser storage remains available. Installing ClockTools does not make the whole site available offline.
A Note From the Creator
