One photo or video and you're done for today

03 · Ranking

Ranked by consistency, not likes

Rankings are decided by verification count, then streak, then completion rate. Likes never change your rank, so it reflects what you actually did.

  • 1st: verification count
  • 2nd: streak (consecutive days)
  • 3rd: completion rate
