Notificant

Notificant makes sure you always remember what you want to. It alerts you with scheduled reminders and has the ability to shuttle notifications across different Macs. Utilizing a free Caramel Cloud account, Notificant can create notifications that can be fired at a scheduled time on your current Mac or on any of the others you own. It lives in the menu bar and stays out of your way until you need it. The simple UI makes it a cinch to create a notification within seconds.

• Growl support.
• Ability to rename devices from the Web app.
• Notifications now fire even without an Internet connection.
• Few minor bug fixes and improvements.
