Why one app store is not enough
An app name only works if it is free in all three places the app has to exist: both stores, and a domain for the support and privacy URLs the stores require on every listing. Checking one store is how founders end up renaming at review time.
This tool queries all three live when you press check. Nothing is pre-computed, and nothing you type is stored.
What this app name checker actually checks
Most "app name" searches only look at one app store. That is the check least likely to stop you, because both stores allow duplicate display names — what stops you is everything the name has to sit next to once the app ships.
- Apple App Store — whether an app is already published under that name
- Google Play — the same question on the other store, where a duplicate splits your search traffic
- Domains — .com, .net and .ai, since your listing needs a support URL and a privacy policy URL
App Store approval is not the same as availability
Apple and Google both let two apps ship under the same display name. What they do not let you share is the bundle identifier, and neither of them checks trademarks for you. App Review has rejected apps under guideline 4.1 for names confusingly similar to an existing app, and a trademark holder can file a takedown at any point after launch.
So a clear result here means "nobody has obviously claimed this yet", not "you are safe to file". Those are different questions, and the second one needs a trademark search.
What to do when the name is taken
A conflict is not automatically fatal — it depends on where it lands and how close the other product is to yours.
- Taken on one store only, in an unrelated category: often survivable, but check the trademark before you commit to artwork
- Taken on both stores: expect discovery problems in store search even if you are allowed to ship
- The .com is gone but .ai or .net is free: workable for a mobile-first product, painful once you need a marketing site
- All three taken: this is a rename, and it is much cheaper now than after the launch assets exist
Before you submit to the stores
Availability is the first gate, not the last one. Once a name clears this check, the work that remains is the work that is expensive to redo later: confirm no registered trademark covers your class, register the domain the same day, and reserve the bundle identifier in App Store Connect and the Play Console before you announce anything.
Renaming after launch means new store listings, new URLs, lost reviews and lost search ranking. The order matters more than the speed.
Frequently asked questions
Yes, entirely. There is no account, no email and no credit card, and results are not stored. The full NameSpyAI report — which adds trademark and web-presence checks — is the paid product.
Technically yes. Apple and Google both allow duplicate display names, and only the bundle identifier has to be unique. In practice a duplicate name splits your store search traffic with the other app, and App Review can still reject a name it considers confusingly similar to an existing one.
No. This tool checks availability on two stores and three domains, not legal rights. A name can be unclaimed in all three places and still infringe a registered trademark. A US or EU trademark search is a separate step, and it is the one that carries real legal consequences.
Because both stores require a support URL and a privacy policy URL on the listing, and most apps eventually need a landing page. Discovering the domain is gone after you have shipped the artwork is the common and avoidable mistake.
Those are the three an app team actually decides between: .com is still what people type, .net is the usual fallback when it is gone, and .ai is where app and AI products have been landing. A longer list mostly adds extensions nobody would ship on. The full NameSpyAI report sweeps sixteen.
The source did not answer clearly — usually a timeout or a rate limit on their side. It never means available. Re-run the check in a minute, or verify that one source by hand.
Available is not the same as safe
This tool covers the stores and three domains. The full NameSpyAI check adds US (USPTO) and EU (EUIPO) trademark search, Google web results, Instagram, Reddit, GitHub, npm and the social handles — across sixteen extensions — then scores every signal into one verdict you can act on.
