Tested every iOS PGP app on the store. This is the one.Most of them are either abandoned, clunky, or make questionable architectural choices. This one gets the fundamentals right. Share extension instead of a Full access keyboard. That really matters. Keys stored in the Secure enclave. Keys.openpgp.org for key discovery is a great and seamless choice. Curve25519 and RSA both supported. The developer clearly knows what they're doing.I think the in-app public key lookup by email is what makes this usable beyond the hobbyist crowd. That one feature solves PGP's oldest practical problem.One genuine request: open source the code. I understand the hesitation. Someone might fork it, slap a new icon on it, rebrand, etc. That's a real concern and it's not fair. But being realistic about the market here, the people who need a serious PGP tool on iOS, actually understand what it does, and are willing to pay for it… that's not a huge crowd. Nobody is getting rich forking this. Meanwhile PGP is one of the most trust-sensitive tools a person can put on their device. We're handing it our private keys. For that specific category of app, the community needs to be able to verify what's actually happening. Nothing against the developer, he seems genuine. But PGP is one of the most trust-sensitive tools you can put on your device and “trust me” is the opposite of what cryptography is supposed to be. Since it’s a paid app a permissive license with attribution protection would keep credit where it belongs while giving users what they need.
Thanks for the nice review.
