Which ASO tool should you pick?

• You’re an indie developer deciding what to build, or growing an app on both stores: GetAppNiche. It’s built around finding a niche that makes money first, then the keywords to win it.
• You have an iOS app and want the cheapest keyword tracking: Astro.
• You edit metadata and screenshots in App Store Connect all the time: ASO.dev.
• You run your ASO through Claude, Cursor or another AI agent and track thousands of keywords: Sonar.
• You’re an agency or a team with many apps: AppTweak, or App Radar if publishing listings is the bottleneck.
• You also run Apple Ads: MobileAction.
• You want your own downloads, revenue and ASO in one dashboard: Appfigures.
• Reviews are the problem: AppFollow.
• You don’t want to pay yet: Appfigures’ Starter plan or ASOMobile’s free plan, plus Apple and Google’s own consoles.

GetAppNiche

GetAppNiche is an app market research and ASO tool for indie developers, covering 3.6M+ apps across the App Store and Google Play. It starts one step earlier than most ASO tools: it shows which niches make money, then which keywords in that niche you can rank for.

• Best for: indie developers and small teams picking a niche, launching, or growing an app on both stores.
• Strengths: keyword difficulty and popularity scores with competitor keyword gaps on both stores; daily keyword rank tracking on both stores, up to 500 keywords; revenue and download estimates for any app; review monitoring for unlimited apps; a REST API and an MCP server for Claude, Cursor and ChatGPT, all in one plan.
• Biggest downside: no free trial (there’s a free account, and a 7-day money-back on the yearly plan). Rank tracking is capped at 500 keywords, and specialist trackers keep longer rank history. The 14–90-day growth windows and trend history are App Store only today.
• Pricing: $49/month, $249/year or $299 one-time (pricing).
• Verdict: the best fit if you want research and ASO in one place without paying for two tools. Try the free App Store keyword tool first; it shows who ranks for any keyword on both stores.

Astro

Astro is a Mac app for App Store keyword tracking, sold as one flat annual license.

• Best for: iOS developers who want to track as many keywords as they like for a small yearly fee.
• Strengths: no cap on how many keywords you track; popularity from Apple Search Ads plus a difficulty score; daily rank updates with history graphs; keyword suggestions from competitors; ratings and review tracking; 60+ countries.
• Biggest downside: App Store only, Mac only, and no market data like revenue or downloads. There’s no free trial, though Astro offers a 14-day refund.
• Pricing: $9/month billed annually ($108/year).
• Verdict: hard to beat on price if all you need is App Store keyword tracking.

ASO.dev

ASO.dev is a native app (Mac, Windows, Linux, iOS and Android) that connects to the App Store Connect and Google Play APIs, so you can edit and publish your listing from it.

• Best for: indie developers and studios who manage their own metadata and screenshots.
• Strengths: App Store keyword rankings checked every 4 hours with Search Ads popularity and difficulty; bulk metadata and screenshot uploads; review replies by hand, in bulk or with AI; Custom Product Pages and product page tests; unlimited apps and keywords from the Indie plan.
• Biggest downside: Google Play keyword analytics isn’t available yet (ASO.dev says so itself). The Indie plan keeps 30 days of history and has no export, and there’s no web version.
• Pricing: Console $19, Indie $39, Pro $89, Marketing $199 per seat per month, less on yearly billing. 3-day trial.
• Verdict: the strongest pick here for working inside App Store Connect; weaker if Google Play keyword data matters to you.

Sonar

Sonar is a web dashboard, CLI and REST API with a hosted MCP server of 63 tools, built for people who run their app business through AI agents.

• Best for: builders who want an agent to do keyword research and tracking for them.
• Strengths: keyword popularity and difficulty on both stores; daily rank tracking with unlimited history in every country; competitor gap analysis; revenue and download estimates; review intelligence with an AI responder; competitor ad tracking.
• Biggest downside: there’s no free plan (a limited free mode exists without an account), and the 7-day trial needs a card. Indie is capped at 10 apps and 1 seat.
• Pricing: Indie $29/month ($290/year) with 2,500 keywords; Agency $149/month; pay-as-you-go API credits from $10.
• Verdict: a good fit for agent-first workflows and high keyword counts.

AppTweak

AppTweak is a full ASO and market intelligence suite on both stores, priced by number of apps.

• Best for: agencies, publishers and teams; the Essential plan is aimed at individuals starting with ASO.
• Strengths: more than 12 keyword research tools and a database of 30M+ keywords in 100+ countries; chance and difficulty scores; competitor metadata, creatives and A/B test history; review analysis; a separate free Market Intelligence plan for download and revenue estimates.
• Biggest downside: price climbs quickly with apps and keywords. Essential tracks 500 keywords with 1 seat and 6 months of history.
• Pricing: Essential from $79/month (5 apps), Grow from $249, Expand from $499; Enterprise on request. 7-day trial.
• Verdict: the safe choice for teams with budget; more than most solo developers need. Our AppTweak alternative comparison covers the trade-off in detail.

MobileAction

MobileAction combines ASO tools with Apple Ads campaign management.

• Best for: developers who run Apple Ads alongside ASO.
• Strengths: keyword research with AI suggestions, volume and difficulty scores; review analysis and AI replies; organic downloads per keyword on Pro; a free Apple Ads campaign manager for up to $10,000 a month in ad spend.
• Biggest downside: the entry plan is small: Lite tracks 100 keywords for 5 apps with 3 months of history.
• Pricing: Lite $15, Basic $69, Pro $239 per month, less on yearly billing. 7-day trial.
• Verdict: worth it if Apple Ads is part of your plan; otherwise compare it with cheaper keyword trackers.

Appfigures

• Best for: developers who want their own downloads, revenue and subscriptions next to their ASO.
• Strengths: a free Starter plan; keyword rank tracking (hourly on paid plans) with alerts; competitor and Apple Ads keywords; download and revenue estimates; reviews with replies and translation.

• Pricing: Connect $9.99 (own-app reporting, no tracked keywords), Monitor $44.99, Optimize $149.99, Boost $399.99, Amplify $1,399.99 per month; about 20% less yearly.
• Verdict: great if you want one dashboard for your own numbers; pricey for competitive research.

AppFollow

AppFollow is best known for review and reputation management across many app stores.

• Best for: app businesses and game publishers answering lots of reviews.
• Strengths: AI review replies in any language, auto-replies, tagging and spam reporting; reviews from the App Store, Google Play and other stores in one inbox; ASO keyword suggestions and competitor monitoring; integrations with Slack, Zendesk and more.
• Biggest downside: no published prices; the pricing page is a sales form.
• Pricing: on request.
• Verdict: the specialist for reviews at volume; not the cheapest way to do keyword work.

Asodesk

Asodesk is an ASO toolkit built around a detailed keyword table.

• Best for: ASO specialists and teams managing several apps.
• Strengths: keyword table with Search Ads popularity, rank, best rank and daily impressions; keyword explorer and metadata optimizer; competitor tracking on both stores; top charts and alerts by email or Slack.
• Biggest downside: replying to reviews is a paid add-on. Pro covers 2 apps.
• Pricing: Pro $59, Guru $199, Power $449 per month, about 20% less yearly. 7-day trial, no card.
• Verdict: solid for keyword-heavy work at a mid-range price.

ASOMobile

ASOMobile is an ASO tool aimed at indie developers and small teams, with a free plan.

• Best for: trying ASO tracking for free, then growing on an affordable plan.
• Strengths: a free plan (20 keywords, 2 apps); rank tracking with popularity; competitor keywords; keyword difficulty on Pro and up; downloads by keyword on Max and up.

App Radar

App Radar (part of SplitMetrics) focuses on keyword research plus editing and publishing listings to both stores.

• Best for: teams that update listings on both stores often.
• Strengths: a keyword database of 100M+ keywords in 90+ countries; a listing editor and bulk editor that publish to both stores; competitor creatives and update history; revenue and download estimates; review replies with AI suggestions.
• Biggest downside: the 7-day trial needs a card, and API access and review replies are add-ons. Prices are shown in euros (App Radar says currency depends on your location).
• Pricing: Essentials €69, Growth €169, Scale €299 per month, less on yearly billing.
• Verdict: a good fit when publishing is the bottleneck, not research.

Sensor Tower

Sensor Tower is the enterprise standard for app market intelligence.

• Best for: large publishers, brands, investors and growth teams.
• Strengths: download, revenue and active-user estimates; ASO keyword rankings and visibility; ad intelligence; game and audience insights.
• Biggest downside: pricing is custom and quote-only, which usually means a sales process.
• Pricing: on request; free sign-up for limited access.
• Verdict: the deepest data here, priced for companies rather than solo developers. See our Sensor Tower alternatives if it’s out of budget.

Free ASO tools from Apple and Google

Before you pay for anything, use what the stores give you for free:

• App Store Connect analytics shows your downloads, conversion rate and where people found your app, including App Store search.
• Product page optimization in App Store Connect tests up to three alternate versions of your icon, screenshots and previews against your current page.
• Apple Ads shows keyword popularity on a 1 to 5 scale when you set up a campaign.
• Google Play Console runs store listing experiments on your icon, graphics, screenshots and descriptions, and its store performance report shows the search terms people used before they visited your listing.

The catch: all of these only show your own app. To see competitors’ keywords, rankings and revenue, you need one of the tools above. GetAppNiche’s free app revenue checker and App Store keyword tool cover a little of that without an account.

What to look for in an ASO tool

1. Keyword scores you can act on. Popularity alone isn’t enough; you need difficulty, so you don’t chase terms you can’t rank for.
2. The stores you ship on. Several tools here are App Store only, or only part-way into Google Play.
3. Rank tracking that fits your scale. Check the keyword cap and how much history the plan keeps.
4. Competitor data. Which keywords your rivals rank for, and how they’re doing, is where most quick wins come from.
5. A price you’ll keep paying. Annual-only plans, per-seat pricing and add-ons change the real cost a lot.
