Prices were last re-checked on September 10, 2026, on the vendors' own pricing pages for AppTweak, Sonar, Applyra, Astro, Appfigures, App Radar, MobileAction, AppFollow, GrowASO and Komori.

Choose an ASO tool around the work you need to finish. Keyword research, review management, screenshot design and market analysis need different features. A small app may need only one of them.
We compared 22 of the best app store optimization tools and services available in 2026 by purpose, published features and dated pricing, with options for solo developers and larger teams. We publish AppDrift, which is included below; we have not run a controlled performance test of every vendor.
Quick answer: the best ASO tool by situation
- Listing work for indie and small teams: AppDrift (Free and paid plans from $9.99/month) brings research, drafts, translation and supported store updates together.
- Keyword research for a larger budget: AppTweak ($949/year Essential, displayed $79/mo; 500 keywords, 5 apps) sells keyword research for both stores.
- Tracking-focused budget options: Sonar ($19/month entry observed September 10) and Applyra ($9.99/month) emphasize keyword capacity; AppDrift Basic, also $9.99/month, tracks 50 keywords and adds drafting, translation and store publishing.
- Native iOS research option: Astro is a Mac app for App Store keyword research, with a $9/month offer observed September 10; AppDrift runs in the browser and covers Google Play too.
- Market and competitor intelligence: Sensor Tower sells download and revenue estimates on quoted plans.
- Best free stack: AppDrift's 24 free tools (audit, keyword difficulty, live rank checker, screenshot editor) + Google Trends for seasonality.
- Review management at scale: AppFollow sells reply automation and review analytics across a large portfolio; AppDrift drafts review replies in the reviewer's language for you to edit and send.
Choose software around your next completed task. A checklist-based listing score does not establish that every app needs localization, particularly when missing localization data was treated as absent. Review the method and limits in our listing-score study before using its sample to set priorities.
What ASO platform is best for indie developers on a budget?
For an indie developer, compare the job and allowance together. AppDrift Basic is $9.99/month for five apps, 50 tracked keywords and 500 tokens, with drafting, translation and connected-store workflows. Applyra, at the same $9.99/month, emphasizes tracking capacity; Astro is a Mac app for iOS research. AppDrift Free covers one app and five tracked keywords without a card, so you can finish a real task before choosing a subscription.
How do the top ASO tools compare on pricing and plans?
Compare the billing period and useful allowance, not just the headline price. The dated checks below range from small monthly plans to annual contracts and custom quotes. AppTweak's displayed monthly equivalent, for example, is billed annually.
The comparison table brings the entry prices together. Read each product's pricing section for apps, keywords, history and seats, and confirm the current offer before subscribing. A trial and a permanent free plan provide different starting points.
Which ASO tools have proven results?
This comparison does not establish that one tool causes more downloads. Vendor case studies can be informative when the population, method and outcome are clear. Use store experiments for supported creative questions and repeated rank observations for visibility. Our Analytics guide separates documented acquisition data from unsupported keyword-level revenue claims.
How we evaluate ASO tools
We compare five practical questions: what the data measures, which stores and countries are covered, what the plan costs, which tasks you can complete, and how the tool fits your team. Check cache dates, limits and access in a trial. Published features do not establish that one vendor's estimates are more accurate.

- Strong geographic filtering capabilities
Cons:

- Shows broad volume ranges rather than exact numbers
- Requires billing information for account setup
Best For
Learning about demand for generic terms, measuring brand vs. non-brand interest, and giving early-stage keyword signals for Play Store-first apps. Works best as a complement to dedicated ASO tools rather than a standalone solution.

Conclusion
These 22 options cover different jobs, from metadata drafts to market estimates. Choose the tool that helps you finish your next task and judge the result with your own app. Teams managing multiple locales should also look for platforms that let you bulk update metadata across markets in a single operation.
The tool is only half the equation, though — the other half is the process you run it with. Our app store keyword research guide covers that workflow end to end, from seeding ideas to tracking ranks.
A good first exercise before you commit to any subscription: pull your competitors' app store keywords and see which gaps you could realistically win.
Start with one tool for the recurring task. AppDrift Free covers one app, five tracked keywords and 50 AI tokens once, plus manual Free-template editing and export with an account. Add another tool when you can name the missing data or workflow it will provide.
Applyra ($9.99/month), Sonar ($19/month), GrowASO (from $19/month), AstroASO ($9/month, iOS only) and Komori ($19.99/month) focus on keyword research and tracking; AppDrift Basic ($9.99/month) adds listing drafts, translation and store publishing to 50 tracked keywords. For a deeper look at zero-cost options, see our guide to the best free ASO tools in 2026. If Sensor Tower's pricing is pushing you away, we've also compared the top Sensor Tower alternatives. AppTweak, Sensor Tower and MobileAction also sell market and advertising intelligence, which AppDrift does not provide.

FAQs
What are the best free ASO tools in 2026?
Public tools and free plans can cover a small workflow. AppDrift Free includes one app, five daily tracked keywords and 50 AI tokens once; Free-template exports require an account. Applyra's permanent free plan covers 1 app and 5 keywords with 7 days of history and no AI. Google Trends and Keyword Planner describe web interest rather than app-store search counts. Compare current allowances in the free ASO tools guide.
What is the difference between ASO tools and app store SEO tools?
The terms usually describe the same category of software: tools for app-store discovery and listing work. Individual products vary; some specialize in keywords, others in reviews, creative work or market data.
How much do ASO tools cost?
ASO tool pricing ranges from free to thousands per month. At the low end, AppDrift Free is $0 with paid plans from $9.99/month; GrowASO is advertised from $19/month and AstroASO is $9/month. Dedicated trackers Applyra ($9.99/month, unlimited keywords) and Sonar ($19/month, 2,500 keywords) charge flat monthly prices. App Radar (€69/month), AppTweak ($949/year; displayed $79/month) and FoxData (price not verified) sit in the mid range. AppVector offers a trial; its current prices were not verified. Enterprise platforms like Sensor Tower, data.ai, and Gummicube offer custom pricing that can exceed $1,000/month. Most tools offer free trials or free tiers to get started.
Do I need an ASO tool if I only have one app?
One app can justify a tool if it saves useful work or supports a decision you repeat. Start with a public check or a small free plan, such as AppDrift Free for one app and five tracked keywords, and complete the task before paying for more capacity.
Which ASO tool is best for indie developers?
For indie developers, AppDrift combines keyword tracking, listing drafts, translation and store publishing from $9.99/month, and its Free plan covers one app with five tracked keywords. Applyra and Sonar emphasize keyword tracking; Astro is a Mac app for iOS research. The lowest price is only useful if the plan covers your store, keyword basket and workflow.
How do ASO tools help increase app downloads?
ASO tools can help you research relevant terms, prepare a clearer listing and follow results. Downloads depend on the app, audience and execution. The download-growth guide explains how to investigate the next problem.
Can ASO tools work for both App Store and Google Play?
Most modern ASO tools support both Apple App Store and Google Play, though coverage varies. AppDrift, Sonar, Applyra, App Radar, MobileAction, AppTweak, and FoxData offer full dual-platform support. Some tools like AstroASO and Komori focus exclusively on iOS. Sensor Tower and data.ai provide cross-platform market analytics. Always verify platform support before choosing a tool, especially if you publish on both stores.
