When evaluating a "copy and improve by 10%" app idea, reading competitor reviews one app at a time doesn't scale. So I built App Store Review Miner, an Apify Actor that:

Pulls the top-grossing chart for any App Store category/country

Fetches each app's recent reviews

Classifies low-rated (≤3★) reviews into 13 complaint buckets

Ranks which complaints are category-wide (real opportunity) vs single-app issues
