ASO Studio
Sensor Tower vs Sonar
Both figures below were read from each vendor’s own pricing page, August 21, 2026 for Sensor Tower and August 21, 2026 for Sonar. We sell an App Store tool of our own and it is not in this table.
| Feature | Sensor Tower | Sonar |
|---|---|---|
| Entry price | Not published custom annual contract | $189 a year on Indie, Agency $99 a month |
| Pricing model | Annual contract, negotiated per customer | Tiered by number of apps |
| Stores | App Store and Google Play, plus market data | App Store and Google Play |
| Free option | No | Not listed |
| API and agent access | Enterprise API | REST API, CLI and MCP server |
| Delivery | Web app | Web app |
The short version
What the choice actually turns on.
Only the rows where these two genuinely differ. Everything they answer the same way is left out, because it cannot decide anything.
- 01
Scripting and AI access. Sensor Tower: api. Sonar: mcp.
- 02
Price. Sonar publishes $189 a year on Indie, Agency $99 a month; Sensor Tower publishes nothing and quotes on request.
- 03
Who each is built for. Sensor Tower sits in the enterprise tier and Sonar in the indie tier, which usually matters more than any single feature.
In its favour
What Sensor Tower does well.
- The deepest market estimate set in the industry, going back years across both stores.
- Ad intelligence, audience data and cross-market analysis no indie tool attempts.
- The data investors and large publishers actually cite when sizing a market.
- Account management, onboarding and custom reporting as part of the contract.
In its favour
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.
- Being on the web, so it works from any machine rather than only a Mac.
- A cheaper annual entry price at $189 for the Indie plan if you need the Android half.
Ours, for the record
There is a third option.
Both cover Google Play, which ASO Studio does not. If your app is iOS only, $59/yr a year covers unlimited apps and keywords on a native Mac app, and you can score your listing free first.
