Notifu: group messaging to help you make plans

If you've ever been in the situation of trying to make plans with a group of people who are all communicating via different methods (SMS, IM, email), then you know how much of a pain it is to keep track of what everyone is doing. Notifu tries to make it easier, with a web app that can send messages to your friends via email, IM or text message, and let you know when they've received them.

On Notifu, you can set up a contact list, complete with groups. You can also set up polls, so your friends can text back a single number to indicate what they prefer to do, and Notifu will count them up for you. Notifu's developers are also very savvy about web platforms, with an iPhone web app available and an OpenSocial app in the works.
