ASO Score
A free 0–100 grade of how well any iOS app's store listing is optimized — title keyword use, description quality, screenshot gallery, ratings health, update freshness and localization — with an itemized list of exactly what to fix, in priority order.
How the score works
Six weighted components from public App Store data: Title keyword usage (20), Description quality (15), Screenshots & device support (20), Ratings health (20), Update freshness (15) and Localization (10). Apple doesn't expose the subtitle or hidden keyword field publicly, so grade those yourself with the metadata checker and ASO checklist.
