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
Categories still gaining new listings, ranked by how much of their existing lineup is churning or losing reviewers — growth without healthy incumbents
Newly-listed apps whose description closely matches a recently-delisted one
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
Which categories are gaining new apps fastest, and which existing apps are losing reviewers right now
