K-Pop Bias Battle

The fastest way to find your true bias.

Stop second-guessing your tier list. Tap through head-to-head matchups between your favorite K-pop idols and a smart ELO algorithm builds your ranking automatically. No dragging, no agonizing. Just instinctive picks that surface the truth.

WHO'S YOUR BIAS, REALLY?

· Two idols at a time. Pick the one you bias.
· A smart ELO algorithm reads your picks and ranks every idol on a clean S / A / B / C / D / F tier list.
· 200+ idols across 36 K-pop groups - spanning 2nd, 3rd, 4th, and 5th generation, girl groups and boy groups, from genre legends to the newest rookies.
· Long-press to drag any idol to a different tier if your gut says so.
