PhoneShare

PhoneShare lets you easily create phone lists or contact lists (an upcoming feature is to load directly from your phone's Contacts). You can sort the entries into different groups, which can be in different configurations for different lists. Afterwards, you can share the lists to your friends and colleagues - both those on the list and anyone you add manually. You can then directly call that person by accessing the list.

Although primarily intended for phone lists, PhoneShare can also be used to send other types of lists (e.g. to-do lists, grocery lists).
