ASO tool comparison
RocketASO vs Sonar
Updated 2026-10-03
Sonar is a browser ASO tool for the App Store and Google Play, aimed at indie developers. Its Indie plan is $29 a month or $290 a year and includes keyword scores, daily rank tracking, and revenue estimates for other apps.
RocketASO reads the App Store and Google Play reports for your own apps, names the one listing fix worth the most this week in dollars, and measures whether that change moved installs.
How they differ
| Aspect | Sonar | RocketASO |
|---|---|---|
| Product | Browser research tool, plus an API and MCP server | Web workspace |
| Stores | App Store and Google Play | App Store and Google Play |
| Who it is for | Indie developers who want keyword scores and rank tracking | Developers and small studios who want the next listing fix from their own store reports |
| Price | Indie is $29 a month or $290 a year | Free public listing audit. Solo is $19 a month for one app on both stores, one seat. Indie is $39 per connected app a month, with its App Store and Google Play versions counted once. Studio is $199 a month. 14 days free, no card. |
| Data | Keyword popularity and difficulty, ranks, and revenue estimates | Connected work uses the developer's own App Store Connect and Google Play reports. Keyword volume and difficulty are never guessed: Apple's own popularity score shows when Apple Ads is connected. Download and revenue estimates for other apps are not offered. |
| After a listing change | Rank tracking on the keywords you follow | Names one listing fix in dollars for the week, then reads whether installs moved. |
When RocketASO is the better fit
- You want the fix chosen from your App Store search report and stated in dollars.
- You want to publish the screenshot or the reply, then read installs.
- You do not want another app's revenue estimate in the decision.
When Sonar is the better fit
- You want keyword scores, a rank tracker, and an API in one indie plan.
- Revenue estimates for other apps are useful to you.
- Research from an assistant through MCP is the workflow.
The bottom line
Sonar is indie keyword research for both stores, with rank tracking and revenue estimates. RocketASO leaves those estimates out and uses your own reports to pick and check a listing fix.
