App store optimization tools help your app rank higher and convert better in the App Store and Google Play, through keyword research, rank tracking, review management, store page testing and competitor data. Choose by the job you need done, because most now sit inside bigger growth suites or come with services. Ten options follow in no particular order.
ASO is SEO for app stores, with its own rules. The store reads your title, subtitle and keyword fields, your ratings and reviews, and how often people who see your listing go on to install. Change any of those and your ranking, and your installs, move with it.
This list is sorted by job, not ranked. The ten tools below are listed alphabetically and in no particular order, and every description comes from each vendor's own website, read as of Oct 2026. If you're wondering whether ASO still deserves your time, my take on whether app store optimization is still worth it answers that first.
ASO tools by job: keywords, reviews, testing and data
I checked the free plan column on each vendor's own website, as of Oct 2026. Yes means the page names a free plan, a free version or an open source edition. Trial only means it names a time-limited free trial. Not stated means the page I read named neither, so check the vendor's own site before you sign up.

ASO has become a feature of bigger growth suites
Here's what the vendor pages show. The App Radar page calls itself an integral part of the SplitMetrics ecosystem of growth products, and MobileAction and Gummicube present themselves as growth partners and agencies as much as software. Several others now lead with AI agents for Apple Ads or with app intelligence rather than ASO.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
So ASO is rarely a stand-alone tool any more. It's a feature inside an app intelligence suite, part of an Apple Ads platform, or a managed service. That's fine, but decide whether you want software your team runs or people who run it for you.
Readers who get this far often ask about the next step, so see my picks of SEO tools for agencies.
Match the ASO tool to the job
- Keyword research and rank tracking. Finding the terms people search in each store and country, then tracking your position daily.
- Reviews and ratings. Replying fast, spotting complaints that point to bugs, and lifting your rating, which affects both ranking and installs.
- Store page testing. Testing icons, screenshots and descriptions to see which version turns more visitors into installs.
- Market intelligence. Downloads, revenue estimates and keyword data for competitors and whole categories.
- Managed services. An agency or growth partner runs the work for you, often alongside Apple Ads.
A simple monthly ASO routine
- Check your rank for your top 20 keywords in each main country.
- Read every new one- and two-star review and reply to the fixable ones.
- Review competitors' new screenshots, titles and keyword changes.
- Run one store page test at a time and let it reach a clear result.
- Update your keyword fields with what you learned, then start again.
Store page testing works on the same principles as website testing. My guide to A/B testing tools covers how to run tests that give you a result you can trust.

My plain advice on app store optimization tools
Pick the job before the tool. If you're an indie developer, one tool that tracks keywords and reviews may be all you need. If you spend heavily on Apple Ads, look at platforms that join Apple Ads and ASO data. If nobody on the team has time, a managed service may get further than software nobody opens.
And treat reviews as part of ASO, not a support chore. They affect your ranking, your conversion and what you build next.

Frequently asked questions
What is app store optimization?
It's improving an app's listing in the App Store and Google Play, including title, keywords, screenshots and reviews, so it ranks higher in store search and more visitors install it.
Is ASO the same as SEO?
The idea is similar, but the stores use their own ranking signals, such as keyword fields, ratings and install conversion, so you need app-specific tools.
Do ASO tools offer free trials?
Several tools on this list name a free trial on their own site, shown in the free plan column. Check each vendor's site for current terms.
Can I test my app store page?
Yes. Some tools here run A/B experiments on icons, screenshots and descriptions, so you can see which version earns more installs.
Should I hire an ASO agency?
If nobody on your team can give ASO regular time, a managed service can help. Several vendors on this list offer services alongside their software.
