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.
