#26 competitive rank

SkillChirp keeps discovery activity and head-to-head Battle results visible as separate signals so traffic alone does not decide a matchup.

How does SkillChirp compare FetchSandbox?

Product-page discovery activity is shown separately from head-to-head Battles. When a live matchup exists, voters compare both products before the community split is revealed.

TRANSPARENT COMPETITION

Matches decide the standings.

Head-to-head votes are deduplicated and automated traffic is filtered. A match win earns 100 season points, a draw earns 40, each verified match vote adds 1 point, and a three-win streak earns a 25-point bonus. Product-page views and outbound clicks remain discovery analytics rather than deciding the game.
