AppDrift vs Sonar: Keywords, Listing Tools and Publishing (2026)

Prices and capabilities checked September 28, 2026 against Sonar's pricing and feature page, its changelog and API documentation, and AppDrift's current plans. Competitor capabilities below are documented offerings, not a hands-on quality comparison. Disclosure: AppDrift is our product.

Short answer: Sonar sells keyword capacity: 2,500 tracked keywords across 10 apps on its Indie plan at $29/month, or $290/year (the price for new accounts since September 15; it was $19). Its toolkit also includes listing drafts, screenshots and alerts. AppDrift starts at $9.99/month with metadata generation, translation into 60+ languages and publishing through your connected store accounts. AppDrift's keyword caps are 50 on Basic and 500 on Pro. For preparing and publishing each release in several languages, AppDrift keeps drafts, translation and store updates in one workspace, starting with a free plan.

Quick Comparison Table

What Is Sonar?

Sonar is a newer ASO tool built for indie developers who felt priced out of AppTweak and Sensor Tower. Its pitch is a flat rate with a large allowance: the Indie plan is $29 a month, or $24.17 a month billed annually ($19 before September 15), for 10 apps and 2,500 tracked keywords on both the App Store and Google Play. The Agency plan at $149 a month raises that to 50 apps, 10,000 keywords and five seats, with portfolio roll-ups and white-label reports.

What you get is keyword research with difficulty scores, daily rank tracking, competitor keyword and rank comparison, and developer tools: a REST API with 1,000 requests a day, a command-line client, and pay-as-you-go API credits from $10 with 50 free on signup.

Sonar also documents listing drafts, a localization manager, screenshots and a monitoring feed. Its public workflow ends with exports and copy-ready fields; we did not verify a direct store-publishing operation. The current pricing page includes all countries. Its App Store Connect integration imports your own downloads and proceeds, which should not be confused with search popularity or per-search-term conversion.

What Is AppDrift?

AppDrift is a browser workspace for listing work on both stores. Use keyword tracking to follow selected terms and metadata generation to prepare editable drafts. It also offers translation into 60+ languages, a screenshot editor and monitoring alerts. Review the prepared content before using connected-store publishing.

AppDrift also offers Apple Search Performance for connected iOS apps: Apple's daily App Store Connect reports of search and browse impressions, product page views and downloads by country. Apple does not share search terms through its API, so keyword positions come from AppDrift's own daily rank checks. The full view needs a paid plan and a connected App Store Connect key.

AppDrift's limits: AI actions are metered in tokens (500 a month on Basic, 3,000 on Pro, 8,000 on Studio; a full generation costs 7 tokens per language on iOS and 8 on Android). Tracked keywords are capped at 5 on Free, 50 on Basic, 500 on Pro and 1,500 on Studio. Competitor rank tracking is a Studio feature. Google Play rank checks see roughly the top 30 results. There is no Apple Search Ads campaign management.

Features Compared

Keyword tracking and research

On volume, Sonar offers 2,500 keywords for $29 against AppDrift's 500 for $19.99. Both show difficulty and popularity information, but the source matters. Sonar's API documentation distinguishes connected Apple Search Ads popularity from estimates and unavailable values. AppDrift's difficulty checker scores the current top-ranking apps. Neither a difficulty score nor search popularity is a measurement of your app's installs from that term.

What happens after the research

Both products help prepare a listing. Sonar documents editable AI drafts grounded in your listing and target keywords, plus screenshots and localization support. AppDrift saves generated metadata and prepares translation drafts in 60+ languages. Separate keyword tools can help you research the wording. You can send reviewed changes through your connected store accounts. If publishing across languages is your bottleneck, try that complete workflow with your own app before choosing.

Monitoring

Both products offer monitoring. Sonar documents a listing activity feed and email alerts for rank drops, competitor moves and review spikes. AppDrift offers configurable rules for listing changes, ratings and ranking regressions, alongside a weekly action plan. Compare the alerts you would act on and the delivery options you need.

Developer access

Both offer API and MCP access. Sonar also documents a CLI and prepaid credits for stateless API lookups without a subscription; ongoing tracking requires a plan. AppDrift includes API access from Basic and offers appdrift-mcp for difficulty, rank checks, ASO scoring and metadata generation. Check that the API or MCP server supports the operations you need.

Pricing Compared

Near $20/month, Sonar provides five times as many keyword slots while AppDrift Pro includes twice as many apps and 3,000 AI tokens. Both have listing and monitoring tools. AppDrift has a lower entry price and connected-store publishing; Sonar's Agency plan adds seats and white-label reports. These are different limits and workflows, so compare the work you need to complete as well as the allowances.

Can You Use Both?

Sonar Indie and AppDrift Basic together cost $38.99/month on monthly billing, and the two overlap substantially in listing and monitoring tools. AppDrift Pro ($19.99) raises tracking to 500 keywords and Studio ($39.99) to 1,500 in the same workspace as the listing work, so check whether one AppDrift plan covers your keyword list before paying for two tools.
