PingMe takes a unique approach to keeping track of things you need to do - it's mobile and interactive. Just create a Ping, set a date and you'll receive a reminder by E-mail or TXT to your phone. You can even create new Pings on-the-fly from your mobile device, or tag your Pings to create contextual to-do lists. Pings are also social allowing you to share, send and receive pings with other users.
