A Sensor Tower alternative built for agentic ASO.

Why developers switch from Sensor Tower

• Prices you can see: Sensor Tower publishes no price list, and every plan is a custom quote through sales. Sonar's Indie plan is $29/month or $290/year, listed on the pricing page.
• No sales call to start: Sonar's 7-day trial is self-serve and full-access (every feature, 10 apps, 2,500 keywords), so you can test it on your own apps the same day.
• ASO is the whole product: in Sensor Tower, ASO is one module among many. Sonar focuses on keyword research, daily rank tracking, competitor keyword gaps and review monitoring for the App Store and Google Play.
• No country packs: every country Sonar supports is included on every plan, with no add-on packs.
• API, CLI and MCP included: the Indie plan includes a REST API (1,000 requests/day), a CLI and an MCP server for AI agents, so you can script keyword research without buying an API add-on.

Switching from Sensor Tower to Sonar

1. Start the 7-day trial and add your apps by name or App Store/Google Play ID. Sonar finds the keywords each app already ranks for, so you have data before you import anything.
2. Copy the keywords you track in Sensor Tower (export them if your plan includes exports) and bulk-paste them into Sonar for each app. Popularity, difficulty and your current rank load right away.
3. Add the competitors you watch in Sensor Tower to see the keyword gaps: terms they rank for that you don't.
4. If you ship on both stores, link the Google Play version to the same product to track both side by side.
5. Set up rank-drop alerts. If your team also relies on market-wide download and revenue data, audience demographics or network-wide ad libraries, keep Sensor Tower for those: Sonar doesn't replace them.

SWhere Sensor Tower is stronger

Built for: Enterprise app publishers, ad agencies, financial analysts, and investors who need market-wide mobile intelligence — not just ASO.

• Industry-standard download and revenue estimates
• Ad intelligence across networks, from its Pathmatics acquisition
• Cross-platform audience and consumer insights
• Trusted source for press, analyst and M&A reports
• Official MCP server (July 2026) for API subscribers

What Sonar doesn't do

• No market-wide download, revenue or audience data: Sonar's revenue figures are rough per-app estimates, not a panel-based dataset like Sensor Tower's.
• Ad Spy covers only the Meta ads and TikTok posts of competitors you track, with no spend or impression data. It is not a network-wide creative library.
• No analyst services, custom data deals or enterprise support contracts.
• Apple reports a popularity of 5 for most long-tail iOS searches, so Sonar's number below that floor (and every Google Play popularity) is its own calibrated estimate, not an Apple figure.
• Sonar is young and founder-led: keyword history starts when Sonar began tracking a term (2026 at the earliest), and there are no account managers or managed services.
