All-22 is a unique fantasy football platform designed for iPhone users, blending elements of traditional fantasy with insights from advanced player grading. Managers are challenged to construct a comprehensive 53-man roster that includes all player positions, utilizing Pro Football Focus (PFF) grades instead of conventional statistics to assess talent accurately. This approach allows for a deeper understanding of player performance and strategic roster management.

The platform is primarily focused on dynasty formats, allowing managers to build rosters over time with options for season-long play as well. League setups accommodate 8, 10, or 12 teams in head-to-head matchups. All-22 aims to enhance the fantasy experience by integrating premium PFF data and plans to introduce additional features like contracts and practice squads in the future.
