KWRDS
KWRDS is an Apple-platform app for App Store Optimization, with tools for keyword tracking, research, competitor analysis, and metadata planning. It runs on iOS and macOS and is designed for managing an app or a portfolio across countries and storefronts. Users can refresh tracked keyword rankings and see position changes by country or storefront. Keyword networks expand seed terms into related terms and combinations using autocomplete queries; the site cautions that these suggestions do not guarantee search volume or rankings. Competitors can be marked direct or similar for comparisons of shared keywords, thematic overlap, and opportunities. A metadata editor drafts an app name, subtitle, and keyword field against live Apple character limits, but users must apply the prepared text themselves in App Store Connect. KWRDS also shows which keywords are covered by other indexed localizations in a storefront and which remain unused. The free plan is free. Pro is €12 a month and Studio is €44 a month; both are marked indicative, not final.
