Mostly solved: performance. 11 of 11 apps run below the store’s typical rate on it — while 12 of 12 still carry billing complaints.

How this is scored

Weighted mean of the sub-scores, weights re-normalized over whatever is computable (nobody's fixed it 25 · how far above typical 20 · how angry 15 · people in the market 15 · room to enter 15 · willingness to pay 10). Fixed anchors map each count to 0–100: breadth and willingness-to-pay are straight shares; the gap’s heat tops out at 4times the store’s typical rate; anger scores star3 as 0 and star1.5 as 100; reach runs 104 to 107ratings on a log scale; room to enter is one minus the leader’s share of shelf ratings. A factor that cannot be counted is dropped and named — never imputed. The site’s one composite (#115, owner decision 2026-08-15); cited industry benchmarks are never blended in.

How this is counted

Every number is arithmetic over the reviews we hold, re-counted weekly — nothing modelled, nothing scored. Themes come from a frozen pattern classifier rather than a model reading reviews, so the same review always lands in the same bucket. A shelf rate is pooled across every app here; the store rate is the same count across 12,122 apps. A complaint is only called a gap when at least half the shelf carries it and at least 20 reviews are behind it — a problem concentrated in one app is that app’s bug.
