Co-founder of Gliph here, thanks for mentioning our work.

We understand that some folks require open source for their secure messaging, and encourage them to seek out solutions that provide that. We encourage more options overall for secure communications.

Gliph isn't just a secure messaging tool. Our mission is to help individuals transact with their peers in a trusted, efficient and delightful way.

Gliph is the easiest way to send Bitcoin, and the only app in the App Store that officially supports sending Bitcoin P2P.

Secure communication with strong privacy controls is a fundamental requirement to accomplish our goal.

I use Gliph pretty much daily, and have since I first read about it (on HN) almost a year ago. Great app.
