Komtu

Komtu will save you time, by coordinating arrival to meetings. Have you ever waited for a meeting to start, only to find out that a key player is severely delayed? Why sit around and wait? Komtu will tell you exactly when to head out and will share your ETA with all attendees.

Komtu also offers a built-in chat. It allows you to chat with fellow attendees, without adding them as permanent chat contacts. This feature is useful when you need to collaborate with someone on a particular event, but don't interact with that person on an ongoing basis.
