Best free ASO tools
Updated 2026-10-03
The useful free ASO tools do one job completely: audit a public listing, count a metadata field, or research keywords. A free tier that hides the report is a trial.
| Tool | Best for | Stores | Price |
|---|---|---|---|
| RocketASO free | An audit of any public App Store or Google Play listing | App Store and Google Play | Free |
| Metadata counters | Title, subtitle, keyword field, and Play short description length | App Store and Google Play | Free, in the browser |
| Public lookup | A public App Store listing, search, chart, or recent reviews | App Store | Free |
| RespectASO free edition | App Store keyword research in a Mac app | App Store | Free edition under AGPL-3.0 |
What does the RocketASO free plan include?
An audit of any public listing, a plain account of what was checked, and keyword ranks for the listing's own terms. Connected store reports and the priced weekly fix are on Indie or Studio.
Are keyword scores free?
Several keyword apps offer a free edition or a trial. Treat popularity and difficulty as estimates until you can read your own search report.
Where do I count the 100-character keyword field?
The keyword field counter on this site checks length, spaces, empty commas, and duplicates.
When the audit is not enough, Solo is $19 a month for one app on both stores, and Indie is $39 per connected app a month, each with 14 days free.
