Ask HN: Would this work? Meetings with timers

So I started noticing that at most of the places I have worked meetings are always exceeding the time, or not that well structured and get off track. Now I have been thinking about making a sample app where you just 1) define the meetings topics. 2) setup the time for each topic. 3) invite & start the meeting. For me it would make sense because now I have a clear overview and I can go back to the meeting later and replay stuff. Would this work for your team? and are you having similar problems with meetings?
