We've developed a self-updating address book, a contact management system that allows you stay up-to-date with all your contacts, hassle-free. Instead of adding, editing & updating all your contact's details, you simply take care of your own "profile" - your contact details: as many or as few as you want. The moment you update or add any information it will get sent to all your contacts - so that next time they call you, they call the correct number, e-mail your new address or drive to your current location.
ambadoo is an active address book - which changes completely automatically. You'll always have the latest information on where people are, and how to contact them. It's however a passive system that doesn't require anything from you - except when you change number, e-mail, address. That's the only thing you need to remember to update.
