App name availability checker
See whether the name you have in mind is already on the App Store and on Google Play, before you design a logo around it.
What the check tells you
- Already in use
- An app carries this exact name. You can often still use it, but you will share every search result with them.
- Clear, but crowded
- Nothing uses the name on its own, though other apps start with it or use it before a subtitle.
- Nothing found
- No exact or near match came back on that store. Apple or Google still has the final say when you create the app record.
How to check if an app name is taken
Search both stores at once
Type the name into the field above. The check searches the App Store and Google Play and answers for each store separately: already in use, clear but crowded, or nothing found.
Confirm it where the decision is made
A store search only sees published apps. On the App Store the answer that counts comes from App Store Connect when you create the app record, because Apple lets a name be used by one app per localization and the record holds the name before the app is public. On Google Play, Play Console accepts any title that meets its metadata policy.
Check the trademark separately
A name nobody has published can still be somebody's trademark. Search your national trademark register before you build a brand on the name.
App name rules on the App Store
An app name is at least 2 and at most 30 characters long. The subtitle under it can be up to 30 more.
Apple lets a name be used by one app per localization. The name is set per language, so an app can carry different names in different languages, and the same name can belong to different apps in different languages.
The name belongs to the app record in App Store Connect, which exists before the app is published: Apple's remedy for a name your own account already uses is to rename that app or remove its record. A name can therefore be in use without appearing in any store search.
The review guidelines ask for a unique app name, and forbid packing it with trademarked terms, popular app names, prices or other phrases that are there only to game search.
Apple's own advice is to be distinctive, and to avoid generic terms and names too similar to existing apps.
You can edit the name until you submit the app for review, and after that whenever you create a new version.
The bundle ID, not the name, is the permanent identifier: it is unique, and it cannot be changed once a build has been uploaded.
App name rules on Google Play
An app name, which Google also calls the title, can be up to 30 characters, with one localized name per language. The short description beside it can be up to 80.

A title may not contain emojis, emoticons or repeated special characters, and should not be in ALL CAPS unless that is how the brand is written.
A title may not claim store performance or ranking, a price, or a promotion.
Google's store listing and metadata pages set no requirement that a title be unique.
The application ID, often called the package name, is what uniquely identifies an app on Google Play. It should never change once the app is published, because Google Play treats a different ID as a different app.
Rules last checked against Apple's and Google's own documentation on . Each one links to the page it comes from.
The limits for the subtitle, keywords, promotional text and descriptions are in the guide to App Store and Google Play metadata limits.
If the name you want is taken
- Add a descriptor, inside the 30 characters
- A short word or two after the name is the usual way through, as long as the whole name still fits the limit and says what the app is rather than listing keywords.
- Keep the name clean and use the subtitle
- On the App Store the subtitle gives you up to 30 more characters, and Apple suggests using it, rather than the name, to say what the app does.
- Look at the other store
- The two stores decide separately, which is why this check reports them separately. A name taken on one is often free on the other.
- If the name is your trademark
- When another developer is using a name you hold trademark rights to, Apple accepts a claim. Its App Store Connect help page on adding a new app links to it.
Common questions
How do I check if an app name is available on the App Store or Google Play?
Type the name into the field above. It searches the App Store and Google Play and reports, for each store separately, whether any app already uses that exact name, plus apps that use it as part of a longer name. A name is often free on one store and taken on the other, which is why the two answers are not merged. The check is free and needs no account.
Can two apps have the same name on the App Store or Google Play?
Sometimes. Apple lets a name be used by one app per localization, so a name that another app already holds in your language is not open to you, while apps localized in other languages can share it. Exact duplicates are rare but real: on 17 September 2026 a search of the US App Store returned two apps named exactly Calculator and two named exactly Compass, from different developers. Google Play identifies an app by its application ID rather than its title, and its listing policies set no uniqueness rule for titles.
Does this reserve the name for me?
No. It only reports what a store search returns right now. You reserve a name by creating the app record in App Store Connect or Google Play Console, and Apple and Google each make their own final decision.
Is a free name also free of trademarks?
No. Trademark rights are separate from App Store listings, and a name nobody has published can still belong to somebody. Search your national trademark register, and take legal advice if the name matters commercially.
How long can an app name be on the App Store or Google Play?
Up to 30 characters on both. On the App Store the name must also be at least 2 characters, and the subtitle shown under it can be up to 30 more. On Google Play the title limit is 30 characters, with a short description of up to 80 beside it. Both stores let you set a different name for each language.
What can I do if the app name I want is already taken?
The usual way through is a short descriptor after the name, inside the 30 characters, or a clean name with the keyword moved to the App Store subtitle. Check the other store as well, because a name is often taken on one and free on the other. If another developer is using a name you hold trademark rights to, Apple accepts a claim, and its App Store Connect help page on adding a new app links to it.
Is the app name the same as the bundle ID or package name?
No. The name is what people see, and you can change it with a new version. The bundle ID on the App Store and the application ID on Google Play, often called the package name, are the permanent identifiers. Apple does not let you change a bundle ID once a build has been uploaded, and Google Play treats a different application ID as a different app.
Can I change my app's name after it is published?
Yes. On the App Store you can edit the name until you submit the app for review, and afterwards whenever you create a new version. On Google Play the title is part of the store listing, which you edit in Play Console. In both cases the new name has to meet the same rules as the first one, and the identifier behind the app stays the same.
