Give them their due
What Sonar does well.
- Both stores in one dashboard, with no second subscription for Android.
- A proper developer surface: REST API, a native CLI and an MCP server on every plan, with the MCP also hosted behind an OAuth sign-in.
- Being on the web, so it works from any machine rather than only a Mac.
- Ad Spy for Meta and TikTok ads, plus team seats and white-label client reports on Agency.

Sonar questions
What people ask.
How much does Sonar cost?
Sonar's Indie plan is $29 a month or $290 a year and covers 10 apps and 2,500 keywords with unlimited competitors. The Agency plan is $149 a month or $1,490 a year for 50 apps, 10,000 keywords and five seats. Both include the REST API, CLI and MCP server, and both start with a 7-day free trial.
Does ASO Studio have a REST API?
Not a hosted one. The MCP server runs inside ASO Studio on your own Mac, which is what lets Claude read and write your keyword data. Agents on that Mac reach it over a local socket that never touches a server; from anywhere else your Mac dials out and we relay messages without storing them. Either way the work is done on your machine, so there is no rate quota to buy.
Which supports Google Play?
Sonar does, in the same dashboard as the App Store. ASO Studio does not and has no plans to. If you ship on both stores, Sonar covers more of your problem in one subscription.
