Ardavan Dehghan vs RPost

The only way to enjoy the thousands of photos drifting in your phone.

A response to the now bloated, shallow, and vanity-driven mainstream social media landscape, Sistina is a refreshing way to enjoy & share your photos. Sistina allows users to easily sort through the overwhelming amount of photos on their phones, and then to view or share them with friends or the public at large through Sistina's delightful interface.

Sistina is bringing the soul back to social media, one “feel good” photo at a time.
