Why not offer a $1.99 version without having to create an account. Everything these days is "create an account", "allow access to contacts", "sync with FB" - gets annoying.
Okay, I tried it based on this. Ideally one could opt into this step, but I think if it either said 1) "view your contacts" or 2) you simply wrote "We never change your contacts or save them on our servers" or similar -- that'd do it, I think.
BTW, once in, I really like it! Simple, elegant, but not too simple (e.g., it supports basic tables).
