App Store niches worth a look
Terms where Apple reports high search demand and no single company holds more than three of the top 10. Thinnest fields first. That makes a term worth a look, not open — each one’s own page says whether its top 10 is thin or already established. No invented score: every number here is one you can check on the App Store.

A term dropping off this list is not “solved” — a company entering with 4 or more of the top 10, or demand falling out of the top two bands, moves it below the bar. Nothing here predicts which comes next.
