Sync Timer

An online stopwatch service. Multiple clients can display a synchronized timer by sharing and controlling a common timer on the server. Supports multiple timers simultaneously.

The Problem

😐 "A group is practicing a presentation in the front of the room and they need help keeping track of time."

😄 "I know! I can use a timer app with a large display on my laptop and turn my screen towards them."

😲 "Oh no, now I can't easily see the screen to check the time or access the keyboard or touchpad to start and stop the timer."

🙂 "I know! I'll setup a second timer on my phone and start both timers simultaneously."

🤔 "Gee, I wish there was a way an easier way to synchronize these two timers..."
