Opening your draft…

Store

Start with your listing copy.

5 fields are empty. Length checks only. An empty optional field is not automatically a problem, and fitting the limit does not make the copy persuasive.

Give the copy a human check

Does the opening explain who this is for and what they get?
Could a competitor use the exact same promise?
Can the product prove every claim?

Unicode code points and bytes can differ, especially for emoji and accents. Verify the final fields in the store console.

Worked example · illustrative

A better draft starts with a clearer promise.

Trail Notes: Hiking Journal is 27 characters. It communicates a product category within a 30-character name field.

Gabriel’s take

Passing a length check is the starting line. The copy still has to describe the real app and matter to its audience.

Try it on your app

Paste a draft title such as Trail Notes: Hiking Journal. Switch stores to check the fields that apply to each listing.

Know what the result means.

What this tool checks—and what it doesn’t

This checks text lengths and basic completeness. It does not measure keyword demand, predict rankings or replace store review.

Where does my work go?

Text and images are processed in your browser. Research tools share a locally saved research project; listing tools share a separate listing project. Other text tools save drafts on this device when browser storage is available; the screenshot checker keeps files in memory only. Clearing browser storage can erase saved projects. Export important work.

Can Gabriel review the result?

Yes. Contact Gabriel with your listing and question to discuss the scope. Tool use is free; professional consulting is agreed separately. No data is automatically shared when you click Contact.

Check the platform requirements

Store requirements can change. Confirm your final fields and assets in the relevant console.
