Sonar is an agentic ASO (App Store Optimization) tool. It gives your AI agent live App Store and Google Play data — search popularity, difficulty, true rankings and competitor keywords — so it can research, rewrite and track your listings in every country. It works in Claude Code, Codex, Cursor, Claude and any MCP client through a hosted MCP server with 63 tools, a CLI and a REST API, or in the dashboard. Around that core sit daily rank tracking, keyword gap analysis, Ad Spy for competitors' ads, review monitoring and revenue estimates. The Indie plan covers 10 apps and 2,500 tracked keywords, competitors uncapped, for $29/month or $290/year, with a 7-day free trial; the Agency plan covers bigger portfolios and teams.

Claude Code, Codex, Cursor and Claude, plus any other client that supports the Model Context Protocol (MCP). Add the hosted server at trysonar.app/mcp — clients with OAuth sign in through the browser, no API key needed — or run the @sonarapp/mcp npm package with an API key. Either way your agent gets 63 tools covering the whole Sonar API. For scripts, CI and agent frameworks without MCP, the same data is available through the sonar CLI (@sonarapp/cli) and the REST API. Setup guides for each agent are at trysonar.app/connect-ai.

Not directly — publishing your listing stays with you. Your agent can set up the workspace for you (add apps, competitors, tracked keywords and alerts), run competitor scans, and use Sonar's data to draft your name, subtitle and keyword field in every language for you to review. It can also build screenshot sets in Screenshot Studio and export store-ready PNGs. You paste the final text and upload the screenshots in App Store Connect or Google Play Console yourself. The one thing your agent can publish is a reply to an App Store review of your own iOS app, through the review responder — that needs an App Store Connect connection with an Admin-role key.

Sonar supports both the App Store and Google Play. You can track keywords, rankings and competitors across both stores from one workspace — in the dashboard or through your agent — with no separate tools or subscriptions. Both stores are first-class: full keyword research, difficulty scoring and daily rank tracking on each.

On iOS, popularity is Apple's own Search Popularity where Apple reports it. Apple shows a flat 5 for every keyword below its floor — most keywords — so there Sonar shows a calibrated estimate built from the apps ranking for the keyword and App Store autocomplete. Since October 2026, iOS rankings follow Apple's own App Store search order. Google Play publishes no search volume, so Android popularity is Sonar's estimate, calibrated against Apple's numbers, from a Play autocomplete probe plus the install counts of the top ten apps. Difficulty on both stores is Sonar's own score, computed from the apps ranking in the top ten.

Popularity (0–100) estimates how much a keyword is searched — higher means more potential traffic. Difficulty (0–100) estimates how hard it is to reach the top of the results — higher means the apps already ranking are stronger and harder to displace. Both are directional scores designed for comparing keywords against each other inside Sonar, not absolute numbers you can line up against another tool, since every ASO tool uses its own scale. The Gap column (Popularity minus Difficulty) highlights the sweet spot: high demand with low competition. For a full breakdown of what goes into each score, see trysonar.app/aso-keyword-scores-explained.

Sonar's difficulty score (0–100) measures how hard it is to break into the top ten for a keyword, judged by the apps already there. On iOS it's driven by the rating counts of all ten ranking apps, with extra weight on the three strongest; on Google Play, by their install counts. Next to the score, Sonar shows how many of the top ten use the keyword in their title and flags keywords where a top-3 slot looks beatable. As a rough guide, 0–30 is low competition (a good opportunity), 30–60 is moderate, and 60–100 is highly competitive.

Every tracked keyword is re-checked once a day, recording your app's rank and your competitors' ranks from the same search. Each day's checks start at midnight UTC and fill in over the following hours, so your dashboard shows the new day's rankings as they land. You can view historical rank trends over time to spot seasonal patterns, measure the impact of metadata changes, and catch ranking drops early. App metadata (ratings, reviews, install counts) is also synced daily to give you a complete picture of how your listing evolves.

Yes — every subscription includes unlimited competitor tracking with no per-app fees. Add any competitor app from the App Store or Google Play and Sonar will monitor their keyword rankings alongside yours. You can compare rankings side-by-side, run keyword gap analysis to discover terms competitors rank for that you don't target yet, and track their metadata changes (new versions, description updates, category switches). Competitor intelligence is one of the fastest ways to find keyword opportunities: if a similar app ranks well for a keyword you're missing, that's a signal worth acting on.

Yes. Sonar is built API-first — keyword, ranking, competitor and review data is available through our REST API, the MCP server and the CLI. Indie subscribers get 1,000 API requests per day across all endpoints (5,000/day on Agency). For API-only users (AI agents, MCP tools, scripts), we offer prepaid credit packs from $10 — no subscription required. Each new account gets 50 free credits on signup. Stateless endpoints cost 1 credit per call (app lookup, search, ASO score, suggestions, reviews, keyword extraction), keyword research costs 10 credits, and bulk revenue calls cost 1 credit per app ID. Credits never expire. API keys use Bearer token authentication with the aso_ prefix. Full documentation with request/response examples is at trysonar.app/docs/api.

The Indie plan is $29/month, or $290/year (which works out to $24.17/month). It covers 10 of your own apps, 2,500 tracked keywords, unlimited competitor tracking, all countries, full ranking history, review monitoring, alerts, and complete API, CLI, and MCP access. The Agency plan ($149/month, or $1490/year) raises that to 50 apps, 10,000 keywords, a 5,000/day API allowance, and 5 team seats. Every subscription starts with a 7-day free trial — you won't be charged until it ends and can cancel anytime. If you only need API access (for AI agents or scripts), prepaid credit packs start at $10 with no subscription.

Yes — free mode. Add the Sonar MCP server to your agent (or call the REST API) without an API key and the core research tools work with no account: app search, app lookup, ASO score, keyword extraction, keyword suggestions and top charts share 30 requests a day per IP, and keyword metrics cover 5 keywords a day. Tracking, rank history and the workspace tools need an account — signing up adds 50 free API credits, and the Indie and Agency plans start with a 7-day free trial. Setup and limits: trysonar.app/aso-mcp.

There's no free plan, but you can get real data without paying. Your AI agent can use Sonar's core research tools in free mode, with no account and daily limits. Three free tools also work in your browser with no signup: the ASO Score Checker (trysonar.app/tools/aso-score) audits any app's metadata, the Keyword Generator (trysonar.app/tools/keyword-generator) turns a seed term into hundreds of scored keyword ideas, and the Keyword Difficulty browser (trysonar.app/keyword-difficulty) has free difficulty scores for thousands of popular app keywords. After signing up you can also browse a read-only live demo of the full product before starting the 7-day free trial, and every new account gets 50 free API credits.

After the 7-day trial, your subscription begins automatically — no action needed. Your data — tracked apps, keywords, ranking history, and competitor groups — is fully preserved. You can cancel anytime during or after the trial from your settings page. The Indie plan is $29/month (or $24.17/month billed annually). The launch deal (50% off for life) is sold out.
