App Store keyword difficulty checker
How hard is it to rank for a keyword, and who is already there. Free, no account. Scored from Apple's own public signals, so there is no paid data provider behind the numbers and nothing to sign up for.
What these numbers mean
Difficulty weighs how strong the apps already ranking are: ratings, rating counts and how many of them deliberately target the term in their title.
Popularity is modeled, not measured. Apple publishes no search volume, so this is a proxy built from autocomplete rank and how many apps compete for the term. Read it as a direction, never as a number of searches.
Opportunity blends the two geometrically, so a very hard keyword cannot score well on demand alone.
Tracking a keyword's rank day by day, across every storefront, is what the full workspace adds. Looking for what to build rather than what to rank for? The free Scout report scores 25 categories of App Store opportunities.
