Question 1

How do I turn an old phone or tablet into a permanent 24/7 desk clock dashboard?

Accepted Answer

Simply place your old phone (iPhone 5s, older Android) or tablet (iPad, Android tablet) on a desk stand or nightstand, open https://clock.lets.gen.in/ in the browser, and double-tap to enter fullscreen mode. The clock uses the Screen Wake Lock API to prevent the screen from sleeping, and its built-in OLED burn-in protection ensures safe, continuous 24/7 operation.

Question 2

Will running this clock on an old smartphone or tablet overheat the device or drain battery?

Accepted Answer

No. The application is built with zero external JavaScript libraries and consumes less than 1% CPU utilization. It includes a dedicated 'ECO' power saver mode that synchronizes CPU ticks to 1-minute intervals and utilizes pure OLED black backgrounds for 0-watt subpixel power savings, keeping older devices cool.

Question 3

How does OLED screen burn-in protection work on this clock?

Accepted Answer

When OLED mode is enabled (default ON), the clock chassis automatically shifts by 1 to 2 pixels along a micro-diamond path every 60 seconds. This imperceptible movement prevents static subpixel burnout on OLED, AMOLED, and mini-LED displays during 24/7 continuous operation.

Question 4

Can I embed this digital clock as a live dashboard widget in Notion or WordPress?

Accepted Answer

Yes. You can embed the clock into Notion dashboards, WordPress pages, Obsidian notes, or custom web dashboards using an iframe: . The embed=true parameter hides the bottom dock for a clean, minimal widget card.

Question 5

Does this digital table clock work offline without internet?

Accepted Answer

Yes. The clock is an offline-ready Progressive Web App (PWA). Once loaded, all assets are cached locally via its service worker, allowing full offline operation. You can also install it to your home screen on iOS and Android to launch directly as a standalone dashboard app.
