Free ASO tools
These are appXL's free App Store and Google Play utilities. Each one does a single job a practitioner actually repeats — checking keyword coverage on a live listing, auditing a store page, generating store badges or custom product page URLs, sanity-checking how hard a keyword is, or reading what reviewers are actually complaining about. They are free and need no signup, though the ones that pull live store data are rate limited so they stay available. Nothing here is a trial of a paid tier; the paid product is the agent that does this work continuously instead of on demand.
Key takeaways
- Every tool solves one repeated ASO task rather than bundling a dashboard you have to learn.
- Free with no signup; live-store checks are rate limited per device.
- The generators (badges, CPP URLs) run in the browser and store nothing.
- The same analyzes run continuously inside the appXL agent for teams that want them ongoing.
How we compared them
Each tool listed here is built and hosted by appXL, works without an account, and states plainly what data it reads. Where a tool depends on live store data we say so, because that is the part that has to be rate limited.
The tools

ASO keyword tool

What free tools can and cannot tell you
A one-off check tells you the state of a listing today. It cannot tell you whether a change worked, because that requires a baseline, a change log and a re-measure after the store re-indexes — typically one to two weeks on the App Store and slightly faster on Google Play.
That gap is the honest case for a paid tool of any kind, ours included. Use the free tools to find the obvious problems, which on most listings is a large share of the available upside, then decide whether the remaining work justifies ongoing tooling.
What data these tools read
- Public store listing data: title, subtitle, description, category, rating and reviews.
- No account credentials. None of these tools connect to App Store Connect or Google Play Console.
- Generators run entirely in your browser and send nothing to a server.
- Live-store lookups are rate limited per device to keep the tools free and available.
Frequently asked questions
Are appXL's tools really free?
Yes. They need no account and no card. Tools that read live store data are rate limited per device so the free tier stays usable for everyone.
Do I need to connect App Store Connect or Google Play Console?
No. Everything here works from public store data, so you can run a check on any app, including a competitor's.
How are these different from the paid appXL agent?
The free tools give you a snapshot on demand. The agent runs the same analyzes continuously, drafts the metadata changes, and tracks what happened after each one shipped.
