Show HN: Is it time yet? Countdowns for Google Calendar

I built this free web app a couple of years ago because I always need to know what meetings are coming up, and I've never found a satisfactory solution. So, here comes a web app that throws countdowns at you, as well as playing ping sounds/flashing the screen when meetings are approaching. I always have multiple screens around, and I dedicate a vertical panel to this app.

Lately, I've upgraded it to also support booking rooms by querying for free rooms and "fast booking" them depending on a custom priority list. I have a personal use case for this one: even periodic meetings don't have assigned rooms, so I can just bulk-book the first available rooms for the next couple of weeks for every meeting that does not have an associated one.

I hope this app can help others find some help for their corporate lives, as it did for me :D
