I bough this app when many features were still not working... but I knew the developed was working on it, and my waiting paid off. This app now fully functions for encrypting, decrypting, using MIT server for looking up names, and most importantly using iTunes to be able to export private keys (public keys can be emailed) so you can have the same private key on an iphone, ipad, and your Mac.
Interface is still a bit clunky which is why its 4 starts, but functionally it all works for sending PGP/iPG/GPG signed or encrypted emails.
If the author keeps improving it, it will move to 5 stars.
