Why an App Store name collision matters
Apple requires App Store display names to be unique, and rejects submissions whose name is already in use. Discovering the collision after you've built the app means a forced rename — new branding, new marketing, and lost momentum right at launch. Even when the exact name is free, a crowded field of similar app names buries you in store search and confuses the users you're trying to reach.
Checking early is cheap; renaming late is not. Nombrio queries the iOS App Store the moment you type a name and shows you the closest existing apps, so you can decide before you commit.
What Nombrio checks
iOS App Store
Exact and near-name collisions, with the closest existing apps and their developers.
Trademark
US trademark risk verdict so you don't build on a name someone already owns.
Domain & social
Domain availability and social-handle checks so your launch surfaces line up.
Frequently asked questions
How do I check if an app name is already taken?
Enter your app name above. Nombrio queries the iOS App Store in real time and reports whether an app already owns the exact name (a conflict), close variants exist (similar), or it looks clear — and lists the closest existing apps with links.
Does the App Store require unique app names?
App Store display names must be unique — Apple rejects an app whose name is already taken by another developer. Even a near-match buries you in store search and risks brand confusion, so it's worth checking before you build.
What else should I check before committing to an app name?
An available App Store name isn't enough on its own. Nombrio checks the same name against US trademark registers, domain availability, social handles, and developer namespaces (npm/PyPI/GitHub/Docker) — so you see every launch blocker in one place.
Do you check Google Play too?
Right now the free checker covers the iOS App Store. Google Play has no free official API, so Android coverage is on the roadmap via a data provider.
