How would you go about coding a group or shared timer? In other words, 4 or 5 of you have a responsibility that someone checks something every 45 minutes. Sometimes a free of you want be able to, so I want a timer we all share, someone checks and resets it when an alarm goes off.

Maybe one already exists? Otherwise, how would you go about coding one?

Users are both iOS and Android. Web based might be every better because more people could check if it could be left open in a browser on a PC.

Thoughts?
 
Almost thinking out loud to myself, I found this site - https://vclock.com/timer/#countdown=00:10:00&date=2019-11-21T08:48:34&onzero=2

I guess that makes sense, put the time you're counting down to in the url. This can be shared, I just need to be able to send the new url out when someone resets it...

Maybe use Google cloud, it reads the new url when it gets sent (code the timer myself, not use the website, so I can update the url in the cloud)
