START WITH THE QUESTION

What are you working on?

PUBLIC APP SAMPLE · iOS

App Store keyword explorer

Bring: Enter a relevant phrase and select the intended App Store storefront.
Get: A limited public app sample with names, publishers, categories and links to inspect.
Next step: Record relevant tasks in your worksheet. Result order is not a live App Store ranking; search demand needs separate evidence.

The phrase goes to Apple’s public API. Public app records are cached for five minutes; your phrase is not saved as a draft.

TEXT · iOS + ANDROID

ASO metadata and keyword checker

Bring: Enter a name, subtitle or short description, plus the relevant store fields. You can also import a public listing name.
Get: Field counts, App Store keyword bytes, repeated words and a separator-cleaned keyword draft.
Next step: Review the wording for one locale, then validate the exact fields in your store console.

Entered drafts are processed to return your review and are not saved as drafts.

FILES · iOS + ANDROID

App Store screenshot size checker

Bring: Choose a screenshot, feature graphic or Play listing icon target and PNG/JPEG files, or enter width and height manually.
Get: Dimensions, format and alpha metadata checked against the selected upload target. Play listing icons also include a file-size check.
Next step: Correct the export, then review whether the caption and visible app screen communicate the same task.

File inspection stays in your browser. The manual size form also works without JavaScript.

COUNTS · iOS + ANDROID

Store conversion rate calculator

Bring: Choose a metric and enter matching outcome and opportunity counts. Add earlier counts for a comparison.
Get: A rate, percentage-point change and relative change, with the selected metric's scope explained.
Next step: Keep the report period, audience and filters with the result. Use the store's experiment report for a test decision.

You enter counts yourself; this calculator does not access your store account.

ENTERED EXPORT VALUES · iOS + iPadOS

App Store preview export check

Bring: Choose a mobile preview family and enter the finished video's dimensions, duration, frame rate, size and format.
Get: A private report comparing entered values with the covered export requirements.
Next step: Review the actual file's encoding, audio and footage separately, then inspect console processing and validation.

No video is uploaded. The numeric form works without JavaScript and does not save an export record.

Need keyword history or a commercial research platform? Read the free vs paid ASO tools guide and use its evaluation worksheet to compare coverage and plan terms.

USE THE OUTPUT

A small ASO round you can finish.

Save your starting point. Keep the current listing, locale, build and the question you want to answer in an audit worksheet.
Check the draft and exports. Review counts and file properties. Then ask whether the words and visible product screen describe the same supported task.
Test the promise. Use the free testing brief builder to describe one safe action. Record expectations, steps and the observed result.
Choose the next change. Keep product observations with the relevant store report. Compare the same scope and preserve an inconclusive result when the evidence is incomplete.

For example, a fictional walk journal promises an offline entry. Check its listing text and exported screenshot sizes, then ask a fresh person to save and reopen a sample entry offline. The outcome tells you which wording or product behavior needs attention. It does not supply a keyword popularity figure or prove a conversion lift.

Using the free ASO tools

Are these ASO tools free without signup?

Yes. The App Store keyword explorer, metadata checker, screenshot size checker, preview export form, conversion calculator and editable ASO templates are free to use without an account. Listing an app for community testing is a separate beta workflow.

Which free tool should I use for Google Play ASO?

Start with the metadata checker for entered name and description fields, the screenshot checker for your selected export target, or the calculator for matched listing counts. Choose Android-specific fields and the metric you actually use.

Does the keyword checker measure search volume or rankings?

No. It checks entered text, field size and repeated words. The keyword worksheet lets you record demand data with its source and date when you have it. A complete field is not evidence of search demand.

Do I need to buy credits to use these tools?

No. These tools and downloads are free. RateMyApp credits fund completed private app-testing reports in the beta; they are not needed for the tools.

Give the next build a fresh look.

Once you have a specific product question, list your app with a private testing task on RateMyApp. Credits fund completed testing reports. Participation and completion times depend on the community.
