Show HN: Big Clock
bigclock.app
It's just a clock, but BIG. Also includes a stopwatch and a timer.
I needed a web-based fullscreen clock but all the ones I could find were either ugly, filled with advertising, or way too bloated for my tastes. So I built my own.
The clocks are big, but the pages are ultra-minimal: one request and less than 16 kB each. They are coded in plain vanilla JS (ES 5) and CSS (2.1), and designed specifically to work on older devices. They should work back to IE7, though I’ve only test on virtual machines.
