Dragging 90 cards into tiers on a phone is misery, so I built a K-pop bias ranker that’s just tap-who-you-like

May 29, 2026

Ranking biases on TierMaker always falls apart for me on mobile. Dragging a wall of portrait cards into tiers with my thumb is so tedious that I quit halfway every time.

So I tried a different approach: it shows you two idols at a time and you just tap your bias. After ~30 quick matchups it works out your full S→F ranking from your picks. No dragging at all unless you want to change a placement at the end.

Right now it’s 216 idols across 35 groups (BLACKPINK, BTS, NewJeans, TWICE, Stray Kids, IVE, aespa, LE SSERAFIM, SEVENTEEN, ATEEZ, and more). Free for ranking any single group. There’s a one-time $2.99 unlock for cross-group all-time bias, by-gen / by-gender splits, and extra share-card themes.

No subscription, no account, everything stays on your phone. Photos are from Wikimedia Commons. iOS only for now.

Mostly posting because I want to know which groups/idols I’m missing, and whether the head-to-head pacing feels right or drags. Genuinely open to “this idol is wrong / this photo is bad” callouts too.
