How this ranking works

  • Apps are ordered by the total their makers paid, highest first. It is not a review or a recommendation.
  • This page filters the global board to apps listed in Development or any category beneath it; "overall" is the global rank.
  • Taking a rank costs $1 more than its holder. Nothing expires; the holder can pay the difference to win it back.
