Accounts has been a very intense project to design and architect. For this reason, it's been released in stages.
The first public beta of the app was largely an MVP, and the current is (even still) a very functional “work in progress.” — While no piece of complex software is ever truly finished, I believe that this one will continue to evolve alongside human needs and nature. We will soon be at a crossroad where Accounts will introduce things that you have never seen before, and the “beta” tag will be removed.
Beta 2.1 is already in development, and the 2.x series marks the introduction of a syncable, native, offline iOS application for managing your contacts and extended networks. It's faster, smoother, and more interactive.
Stay tuned for more updates!
