Cheap ASO tools for indie developers: what $0, $10 and $30 a month buys

The cheapest ways to track App Store keywords in November 2026 are free plans (Fledly, ASOWeb, ASOMobile, AppStance, AppFollow and Astro all have one) and paid plans of $7 to $9 a month: ASOWeb Pro ($6.99, 200 keywords), Fledly Pro ($9 a month or $79 a year, 500 tracked searches, web) and Astro or AppSprint ($108 a year, unlimited keywords, Mac apps). At about $30 a month, Sonar Indie and aso.dev Indie (billed yearly) add more keywords, Google Play (Sonar) or unlimited apps (aso.dev).

#Every free plan and cheapest paid plan

"Not published" means the vendor's own pages don't say. A free trial is not counted as a free plan. AppFollow, App Radar and AppTweak showed euro prices to our European connection; their US dollar prices may differ.

#What $0 a month buys

• Fledly Free: 1 app, 15 tracked searches and 3 competitors, with daily rank checks, the top 3 app ideas and young earners, and access from Claude, ChatGPT and other AI assistants through MCP. A tracked search is one search term in one App Store country.
• AppStance Rank Free: 2 apps, 100 keywords and 5 competitors with daily rank tracking, iOS only.
• ASOWeb Free: 1 app, 25 tracked keywords in one storefront, 30 days of history; it does not expire and needs no card.
• ASOMobile Free: 2 apps and 20 keywords.
• Astro's free version: up to 10 keywords in the Mac app.
• AppFollow Free: 2 apps with ASO tools, review analysis, 7 days of history and its MCP connector. The pricing page's plan table lists 500 keywords and its FAQ says 1,000 keywords in all countries.
• Appfigures Starter: your own apps' downloads and revenue for up to 5 connected apps, but no keyword rank tracking.

You can also get two things for free from Apple: your own impressions and conversion in App Store Connect, and search popularity for any keyword in Apple Ads. Fledly's free tools check metadata and build a keyword field without an account.

Sonar has no free plan; its free mode lets an AI agent pull metrics for 5 keywords a day without an account, but tracking needs a paid plan.

#What about $10 a month buys

• Fledly Pro, $9 a month or $79 a year: 5 apps, 500 tracked searches, 10 competitors per app, daily ranks in 16 storefronts, every app idea and young earner with revenue estimate ranges, email rank alerts and a Monday digest. iOS only, in the browser and through MCP.
• Astro, $108 a year: unlimited apps and keywords in more than 60 countries, as a Mac app (macOS 14 or later). There is no monthly option.
• AppSprint Pro, $108 a year: unlimited keyword tracking and suggestions in a Mac app, one licence for two Macs. No monthly option is shown.
• ASOWeb Pro, $6.99 a month or $69.90 a year: 3 apps, 200 tracked keywords, 3 storefronts, iOS and Android.
• Mobile Action Lite, $15 a month or $12.50 a month billed yearly: 5 apps, 100 keywords and 3 competitors per app, App Store and Google Play.
• Appfigures Connect, $9.99 a month or $7.99 billed yearly: your own sales, downloads and reviews in one place, but its pricing page lists 0 tracked keywords. Keyword tracking starts on Monitor.

At this price the choice is mostly about form: Fledly if you want a web app with idea research and MCP; Astro or AppSprint if you prefer a Mac app with no keyword cap and pay yearly.

#What $30 a month buys

• Sonar Indie, $29 a month or $290 a year: 10 apps, 2,500 keywords, all countries, App Store and Google Play, with a hosted MCP server, CLI and REST API. A 7-day trial needs a card.
• aso.dev Indie, $29 a month billed yearly ($348), or $39 billed monthly: about $30 only on the yearly plan. Unlimited apps and keyword sets, 60 countries, 30 days of keyword history, App Store only, as a desktop app.
• Fledly Studio, $24 a month or $199 a year: 20 apps, 2,500 tracked searches, 25 competitors per app and 3 team seats. iOS only.
• AppStance Rank Basic, $19 a month: 5 apps, 1,000 keywords, 30 competitors, iOS only.
• ASOWeb Studio, $17.99 a month or $179.90 a year: 10 apps, 1,000 keywords, all storefronts, 10 seats.
• AppFollow ASO, €29 a month or €19 a month billed yearly: 2 apps with keyword suggestions, advanced keyword tracking and 30 days of history, iOS and Google Play.

At this price, Sonar is the one to pick if you need Google Play too, or an API to script your ASO.

#Just above $30

• Appfigures Monitor, $44.99 a month ($35.99 billed yearly): 100 keywords with daily ranks, plus your own sales and reviews from App Store Connect and Google Play. If you want your own numbers and rankings in one dashboard, this is the plan.
• ASOMobile ASO Indie, $59 a month ($47 billed yearly): 5 apps, 500 keywords.
• Asolytics Start, $59 a month ($49 billed yearly): 2 apps, 2,000 keywords.
• App Radar Essentials, €69 a month (€58 billed yearly): 2 apps, 500 keywords, more than 100 countries.
• AppTweak Essential, €99 a month (€79 billed yearly): 5 apps, 500 keywords, more than 100 countries.

#How to compare the numbers

• What counts as a keyword differs. Fledly and ASOWeb count one search term in one country as one tracked keyword, so 500 tracked searches can be 250 terms in two countries. Tools with "all countries" or "unlimited" plans count differently. Check which way your tool counts before you compare.
• Yearly prices look cheaper. Astro, AppSprint and aso.dev show their lowest prices billed yearly; Astro and AppSprint offer no monthly option at all.
• Mac apps vs web. Astro, AppSprint, aso.dev and Wow Keywords run on your computer. Web tools keep tracking while your Mac is off and work for a team.
• iOS only vs two stores. Fledly, Astro, AppSprint, AppStance and aso.dev are App Store only. If you also ship on Google Play, Sonar, ASOWeb, Mobile Action and Appfigures cover both.

#Which one suits whom

• One app, no budget: Fledly Free, AppStance Rank Free or Astro's free version, plus Apple Ads popularity.
• A few iOS apps, about $10 a month: Fledly Pro on the web, or Astro or AppSprint on a Mac.
• Many apps or keywords, or both stores, about $30 a month: Sonar Indie, or aso.dev Indie billed yearly if you're iOS only and like a desktop app.
• Your own sales and rankings together: Appfigures Monitor at $44.99.
• Deciding which app to build next: Fledly, on every plan: it scores app ideas from young apps that already earn on the Top Grossing charts. The other tools here are built around apps you already have. See how Fledly scores app ideas.
