Contaxt - put context around your contacts!
Contaxt takes your address book to the next level. Contacts are geo-tagged so you can see where you met someone (or find them if you forgot their name). You can also sort your contacts by first name, last name or date added. Contaxt allows you to easily share your contact information with the person you just added (through universal vCards) so only one person has to do manual data entry. Most importantly, Contaxt can (with your permission) import all of your existing contacts so you aren't starting from scratch!
