Hi Product Hunt! I built Digital Clock Online because I wanted a clean full-screen clock for my second monitor — something to glance at while working, without installing yet another app. Everything I found was either covered in ads or asked me to sign up first.
So I made a simple web clock that just works: open the page, hit fullscreen, done. It has six retro themes (my favorite is the flip clock), 12/24-hour toggle, and it uses the Wake Lock API so your screen stays on. It even works offline after the first load.
It's completely free, no account, no ads. Would love to hear what themes or features you'd want next!

honestly love how simple this is, the wake lock feature is super handy for my desk setup. one thing i'd love is a pomodoro or countdown timer mode built into one of those retro themes, basically turning it into a focus clock when you need it.

@nuranuvfc Love this suggestion! A pomodoro/countdown mode built into one of the retro themes is actually a great fit for the clock. I'll definitely be considering it for an upcoming update. Thanks for the input!

A fullscreen clock with retro themes sounds perfect for my desk setup. One thing that would make it even better for me: a pomodoro mode with a 25/5 cycle that switches the clock color or flashes the display gently when the break starts, so I can actually notice it from across the room.

@erolhurd That's a killer suggestion. The idea of using the whole screen as a visual notification for the Pomodoro break is genius — way better than a tiny popup.I'm noting this down for the next update. Quick question: what colors would you personally find most soothing for the 'break' state? Just so I can pick the right palette.

Love how the flip and LED themes actually feel authentic instead of just being a font swap. The Wake Lock detail is a nice touch too, shows you thought about real desk use.

Genuinely useful little tool. The LED theme is surprisingly crisp and the wake lock feature actually works on my laptop, which is rare for browser apps.

The flip clock theme is genuinely nostalgic, like something out of an old airport. Wake Lock actually keeps my monitor on during long sessions, which is a small but really thoughtful touch.

Love how the Wake Lock actually works without permission prompts—pretty rare for a tool this simple, and the flip theme nails that vintage feel.
