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
Stores. Sonar covers the App Store and Google Play; Astro is App Store only. If you ship on Android this decides it before price does.
- 02
Where it runs. Astro: mac app. Sonar: web.
- 03
Price. Astro starts at $108 a year, billed annually; Sonar at $189 a year on Indie, Agency $99 a month.
In its favour
What Astro does well.
- Broader Apple coverage: tvOS, watchOS and Mac apps as well as iPhone and iPad.
- More storefronts, at 60-plus countries, with daily ranking updates and historical charts.
- Built-in DeepL translation, which matters a lot if you localize into many languages.
- A mature, well-liked product with a longer track record than ASO Studio has.
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.
If neither shape of bill fits, ASO Studio is $59/yr a year flat for unlimited apps and keywords, App Store only, with a free App Rating check that needs no account.
