ASO Studio
FoxData vs Sonar
Both figures below were read from each vendor’s own pricing page, August 21, 2026 for FoxData and August 21, 2026 for Sonar. We sell an App Store tool of our own and it is not in this table.
| Feature | FoxData | Sonar |
|---|---|---|
| Entry price | Not published ASO, ad intelligence and API priced apart | $189 a year on Indie, Agency $99 a month |
| Pricing model | ASO, ad intelligence and API sold separately | Tiered by number of apps |
| Stores | App Store and Google Play | App Store and Google Play |
| Free option | Free trial and free ASO tools | Not listed |
| API and agent access | API product | 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
Trying it. FoxData: trial. Sonar: none. A permanent free plan and a trial that expires are not the same offer.
- 02
Scripting and AI access. FoxData: api. Sonar: mcp.
- 03
Price. Sonar publishes $189 a year on Indie, Agency $99 a month; FoxData publishes nothing and quotes on request.
- 04
Who each is built for. FoxData sits in the mid-market tier and Sonar in the indie tier, which usually matters more than any single feature.
In its favour
What FoxData does well.
- Ad intelligence, which is a genuinely different product from keyword research and something ASO Studio does not attempt.
- A set of free ASO tools anyone can use, alongside the trial.
- Google Play as well as the App Store.
- An API product for teams that need to pull data into their own systems at volume.
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.
