ASO tool turns any App Store app into a ready-to-paste 100-character Keywords field for ASC — built for indie developers who don't want a $30-a-month web subscription to do keyword research. Add an app, click Analyze, and ASO tool will: • Mine the app's title and description for seed keywords using language-aware stopword filtering (English, German, French, Spanish, Italian). • Expand every seed with Apple's autocomplete suggestions. • Run a full competitor scan — narrow mining from your top seeds, then wide mining across every ranked candidate. • Rank every candidate against the app's real App Store position for that term. • Score each keyword with a transparent heuristic: rank, source, length, and title-overlap penalty. • Pack the highest-scoring tokens into a 100-character keyword string — and a 30-character subtitle — that respects every App Store Connect rule. WHAT YOU GET • A 100/100-character keyword string, ready to paste into App Store Connect. • A 30/30-character subtitle suggestion. • A full breakdown table — every keyword with its rank, score, source, and parent seed. • A list of mined competitors and the seeds each contributed. • One-click Copy buttons next to every output. ON-DEVICE, ALWAYS ASO tool talks only to Apple's public Search API. No accounts, no telemetry, no cloud sync. Every HTTP response is cached on your own disk, so re-running an analysis after a release takes seconds instead of minutes. PRICING • Free — track and analyze one app, with the full pipeline. No watered-down preview. • ASO Unlimited — one-time purchase . Unlimited apps, forever. No subscription, no auto-renewal. REQUIREMENTS macOS 14 Sonoma or later. Network access required for the iTunes Search API. ASO tool is a developer utility, not a guarantee. It optimises what you can paste into App Store Connect — your screenshots, release notes, and reviews still matter.
