My team has been doing a lot of teaming (mob programming) recently, and we've tried different tools to keep time in sync and be ready for the following driver's turn.
But the tools we used were overkill when we only needed a timer. So I prototyped a minimalist one that is always in sync for everyone connected.
It's in its early stage and needs a better design, but it's functional. So I'm sharing it here in the hope it can be helpful to others.
It's a VS Code Extension, but it can also be used via browser (https://linkedtimer.com) in case your team uses another IDE/Editor during these sessions.
I'm also considering making a browser extension when it gets more stable.
