About the Full-Screen Clock

The Full-Screen Clock turns your entire browser window into one large, easy-to-read time display. Instead of squinting at the small clock tucked in the corner of your taskbar or menu bar, you get oversized digits that stay legible from across a room. It is built for situations where the time needs to be glanceable rather than hidden: a desk during deep work, a kitchen counter while cooking, a podium during a talk, or a spare phone propped up as a bedside display. One click expands it to fill the screen, and a second press of the Escape key brings the normal page back.

Reach for this tool whenever a standard system clock is too small or too cluttered to read at a distance. Teachers project it onto a smartboard so a whole class can pace an exam without anyone asking how much time is left. Presenters and debaters keep it on a confidence monitor to stay on schedule. Remote workers park it on a second monitor as a constant time reference, and streamers capture the page as a browser source in OBS to add a clean on-screen clock to a broadcast. Because the readout is large and high-contrast, it doubles as a simple lobby or waiting-room display.

Under the hood it is pure client-side JavaScript. Your browser reads the current time directly from your device clock and repaints the digits roughly once a second, so the time shown is exactly as accurate as the machine you are on. Pressing the full-screen control calls the browser's native Fullscreen API to hide tabs, the address bar, and the operating system chrome; F11 does the same thing on most desktop browsers. Nothing is fetched from a server to tell the time, which means the clock keeps ticking even if your internet connection drops after the page has loaded.

Privacy and accuracy are both straightforward here. The clock never sends your time, location, or activity anywhere because it relies entirely on your own device's system clock and time zone settings. If the displayed time looks wrong, the fix is almost always on your device, not the page: enable automatic date and time in your system settings so it syncs against a network time source. For long unattended sessions, note that most browsers will dim or sleep the screen on their own, so pair the clock with your operating system's keep-awake or caffeine setting if you need it to stay lit overnight.

Frequently asked questions

How do I make the clock fill my whole screen?

Click the full-screen button on the page, or press F11 on most desktop browsers, to hide the tabs and address bar so only the clock is visible. Press the Escape key (or F11 again) to return to the normal view.

Is the time accurate?

The clock reads the time straight from your own device, so it is exactly as accurate as your computer or phone. If it looks off, turn on automatic date and time in your system settings so your device syncs with an internet time server.

Will the clock stop if my internet disconnects?

No. Once the page has loaded, the time is calculated locally in your browser with no further server calls, so the clock keeps running even with no connection.

Can I use this as a clock overlay for OBS or streaming?

Yes. Add the page as a Browser Source in OBS or similar software and paste the page URL. It then appears as an on-screen clock you can position and resize within your scene.

How do I keep my screen from going to sleep while it shows?

Browsers do not block the system screensaver on their own, so use your operating system's keep-awake feature (such as a caffeine or presentation mode) to stop the display from dimming during long sessions.

Spin to Decide: Why a Random Wheel Makes Hard Choices Easier

By the Super Simple Digital Tools Team · Updated June 2026

A spinning wheel looks like a toy, but it solves a real problem: the small decisions that drain more energy than they deserve. Where to eat, who goes first, which task to tackle, what to watch on Friday night. These choices rarely have a wrong answer, yet groups can argue over them for longer than the activity itself lasts. Handing the call to a wheel converts an open negotiation into a single, neutral event. Nobody has to defend a preference or feel responsible for the outcome, because chance, not a person, made the pick.

Fairness is the wheel's strongest practical feature. In a classroom, calling on students by raised hands quietly rewards the same confident few; a random spin gives every name an equal slice and an equal turn, which keeps participation honest and visibly so. The same logic powers live giveaways: when an audience watches the pointer slow and land, the draw feels transparent in a way a behind-the-scenes selection never does. Equal-sized segments are the key. As long as each entry occupies the same arc, the probability is uniform and no option is secretly favored.

There is also a quieter psychological payoff. Researchers who study random decision aids have found that the spin itself often acts as a catalyst rather than a verdict. The moment the wheel is in motion, you frequently notice which result you are quietly rooting for, a gut check that surfaces a preference you had been too cautious to name. In that sense the wheel does not replace your judgment; it shakes it loose. Many people glance at where the pointer lands, feel a flash of relief or disappointment, and then act on the feeling rather than the slice.

When the stakes are higher, the evidence is striking. In a large field experiment led by economist Steven Levitt, more than 20,000 people facing genuine dilemmas, from changing jobs to ending relationships, flipped a virtual coin to help decide, with heads meaning make the change. Those nudged toward change were more likely to follow through and reported being noticeably happier six months later than those told to keep the status quo. The takeaway is not that chance knows best, but that many of us are too cautious, and a random prompt can break the inertia that keeps us stuck.

Used well, then, a wheel is a commitment device. It forces a clean end to deliberation, a moment of choice closure after which the matter is settled and you can move on. Keep it for the decisions that genuinely don't warrant more analysis, and treat the result as either a final answer or a feeling-finder, depending on how the spin lands in your gut. For anything regulated or legally binding, step up to a certified method. For everything else, the wheel is a fast, fair, and oddly satisfying way to just decide.

  • Remove each winner before re-spinning when you need every name picked exactly once, such as assigning turns or seats with no repeats.
  • Keep lists to a few dozen entries so each slice stays wide enough to read; for very long lists, run it in rounds instead.
  • For live giveaways, read the full entry list aloud before spinning so the audience sees that no name was added or removed after the draw.
  • Treat a tough personal spin as a gut check: notice which result you were hoping for as the wheel slows, and let that reaction inform your real choice.
