Where the data points to room for a new app, plus market signals worth knowing about — candidates to look into, not verified conclusions.
Widely requested in reviews, but few active apps' own listings plausibly cover it — addressing-app counts are candidates, not verified, so check the linked apps before assuming a gap is real
Market signals
Notable activity among existing apps — not room for something new, but worth knowing about
Complaint themes that show up across many unrelated apps' reviews
Apps whose listing reads least like what their own reviewers actually describe using them for — a relative ranking, not a confirmed mismatch, since the review-summary text is itself AI-written
Newly-listed apps whose description closely matches a recently-delisted one
Categories still gaining new listings, ranked by how much of their existing lineup is churning or losing reviewers — growth without healthy incumbents
Which categories are gaining new apps fastest, and which existing apps are losing reviewers right now
