Show HN: I made a clock for my old phone. No app, no ads, no signup

Like many of you, I spend most of my day with my IDE/game in fullscreen mode. It's great for focus, but I constantly found myself breaking my flow just to check the time -- quitting fullscree mode or waking up my phone. It's a small annoyance, but it adds up.

At the same time, I had an old phone sitting in a drawer, gathering dust. The screen was still perfect, so I thought: why not turn it into a dedicated desk clock?

I looked for existing solutions, but most were native apps requiring an install, cluttered with ads, or just didn't look right. So, I decided to build the tool I wished existed.

It's a dead-simple, fullscreen flip clock. As the title says: no app to install, no ads, and no signup needed. Just open the URL on your device, and you're done.

My plan is to always keep this core flip clock experience exactly as it is now: free and simple. To support the project, I might add more advanced widgets in the future as optional, paid features, like photo gallary, todo list, weather, timer, etc.

So, my question for you is: What's the one widget you would find most useful on a dedicated dashboard device like this?

I'd love to hear your feedback and ideas!
