 - [CryptPad][cryptpad]: like [etherpad][etherpad], CryptPad allows collaborative note-taking, and includes an option to optimise the pad for code by including line numbers and a monospaced font.
 - [HackMD][hackmd]: another collaborative authoring tool, this time set up for [Markdown][markdown]. HackMD allows you to display the raw MD, the rendered version, or both in a split display, and to save documents in a collection to refer back to in the future.
 - [Time and Date][timeanddate]: convert meeting times between timezones; announce events across timezones; find out how likely it is that your collaboartors are awake right now; etc
+- [Cuckoo Remote Timer][cuckoo]: a shared countdown timer, useful for remote co-working sessions and meetings. Start a countdown timer and everyone connected to the page receives a notification when the countdown ends.
