Sonar is an App Store Optimization (ASO) tool built for indie developers managing multiple apps — without the enterprise price tag.

Find the keywords you can actually rank for: get real search volume, difficulty scores, and autocomplete data for every keyword on the App Store and Google Play, plus daily rank tracking and competitor intelligence.

What you get

- Keyword research — volume, difficulty (0–100), and autocomplete suggestions across both stores

- Daily rank tracking — see how your metadata changes move the needle

- Competitor analysis — spot gaps in their keyword strategy and steal the wins

- Revenue estimates — installs × retention × IAP signals, the kind of data Sensor Tower charges thousands for

- API + CLI included — automate workflows or plug into your AI agents

- Both stores, one dashboard — no switching tools or stacking subscriptions

Why it exists

Sensor Tower is $1,000+/month. AppTweak is $166. Both are built for big publishers. Sonar gives indie hackers the same data for $19/month (annual) - unlimited apps, unlimited keywords, full history.
