1. Keeps track of time I am spending on certain tasks (so I don't spend too much time).
2. Allows me to check-in what a coworker _may_ be doing so as to see if now is a good time to interrupt them.
3. Can be used to keep track of hours for hourly pay
4. Items can be put on to remind me things I need to do that day with reminders if needed.
I highly recommend this for remote teams and I look forward to see where it goes (though it already has a lot of features now).
