From keyword idea to top-10 ranking
App Store Optimization starts with understanding what your users search for. Sonar pulls keyword data directly from Apple Search Ads and Google Play autocomplete to show you real search popularity — not estimated guesses. Each keyword gets a difficulty score (0–100) based on competitive analysis of the top 10 ranking apps, so you can focus on terms where you have a realistic chance of ranking.
Add your app and Sonar tracks your position for every keyword daily. See which metadata changes move the needle, catch ranking drops before they cost you downloads, and monitor competitors to find gaps in their keyword strategy that you can exploit. The keyword gap analysis compares your rankings against any competitor to surface high-opportunity terms they rank for but you don't target yet.
Unlike enterprise ASO tools that charge $150–500/month, Sonar is built for indie developers managing app portfolios. Unlimited apps, unlimited keywords, both stores, full historical data — plus a REST API and CLI so you can automate your workflow or integrate with AI agents. Start with the 14-day free trial, no credit card required.
