Whether or not that something is better, however, depends very much on the use case. RedPhone and TextSecure are designed for very specific use cases (phone calls and text messages, respectively), whereas GnuPG is designed to be general-purpose and universal regardless of use case. Most jarringly, neither of those programs address email or file encryption/verification, and thus do nothing in GnuPG's primary realms of usage; by comparing them, you're basically comparing apples and crowbars.
