App Name Availability: How to Check Before You Build

The App Store Search Lie (And Why Everyone Falls For It)

You've got a name. You search it in the App Store. Nothing comes up. You feel that little dopamine hit — it's mine — and you go build.

Six weeks later, you submit to Apple and get this error: "The Application Name you provided has already been used."

Except there's no app by that name. It's not live. You can't even find it. So what happened?

Someone reserved it. And Apple's reservation system is invisible to the public.

This is the most common app naming mistake in 2026, and almost no guide talks about it. So let's fix that.

Why a Public Search Tells You Almost Nothing

When you search the App Store as a regular user, you're seeing published apps. That's it. What you're not seeing:

• Apps that are reserved in App Store Connect but haven't been submitted yet
• Apps that are under review by Apple
• Apps that have been reserved and let expire but are within a grace window

Apple allows developers to reserve a name for up to 120 days from inside App Store Connect — without uploading a single line of code. During that entire window, the name is locked. To everyone on the outside? It looks completely free.

Google Play is a different story. Android doesn't enforce unique display names at all. Two apps can have the exact same name on Google Play simultaneously. What must be unique is the package name — the technical identifier like com.yourcompany.yourapp — which nobody sees except developers and the Play Store system. So a public search on Google Play is even less reliable as a name check.

The bottom line: Searching the stores publicly is a first pass, not a clearance check.

The Right Order to Check (And Why Order Matters)

Most guides give you a list of things to check. Almost none tell you which order to do it in — and the order is actually the whole point, because each step can change your decision.

Here's the sequence that makes sense before you invest time in building:

Step 1: Apple App Store Connect (the only definitive iOS check)

You need an Apple Developer account ($99/year) to do this properly. Inside App Store Connect, go to My Apps → + → New App, enter your name in the Name field, and try to proceed. If the name is taken or reserved, you'll see an error immediately. If it clears, the name is available — and you can reserve it yourself right then by saving the draft.

Don't have an account yet? At minimum, search the public App Store. Not finding anything is promising but not conclusive.

Step 2: Trademark databases

This is where most founders skip ahead too fast. Before you fall in love with the name and buy a domain, run it through:

• USPTO TESS (US) — free, search exact matches and phonetic equivalents
• EUIPO (EU) — if you're building for a European market
• WIPO Global Brand Database — for international coverage

The key thing to understand here: you don't need to be infringing an exact match to have a problem. Trademark law uses a "likelihood of confusion" standard. If your app is called FlowSpace and there's a registered trademark for FloSpace covering productivity software in Class 9, you could be in range.

Class 9 is the classification that covers software and apps. Search it specifically.

Also worth knowing: trademark rights don't require registration. A developer who has been selling an app called Driftly for two years — even without a registered trademark — may have what's called common law trademark rights. A store search won't surface that. Google will.

Step 3: Domain and social handles

Once you've passed the trademark screen, lock down your digital real estate:

• .com is still the priority. If it's taken, check .app, .io, .co as alternatives.
• Social handles across Instagram, TikTok, X (Twitter), YouTube — ideally all the same
• Tools like Namechk or KnowEm do this scan in one pass

The reason you do this after trademark and before Google Play: if the domain and handles are taken by an active brand in your category, that's a soft signal of either a conflict risk or a crowded naming space. Either way, worth knowing before you commit.

Step 4: Google Play Console

Create a developer account ($25 one-time) and try to create a new app with your name. Because Google allows duplicate display names, this won't tell you much about naming conflicts — but it will let you reserve your package name, which is permanent and unchangeable after you publish. Choose it carefully: reverse-domain convention like com.yourcompany.appname is standard.

Step 5: A similarity scan

The final check is one most articles skip entirely: searching for apps, tools, and brands with similar (not identical) names. This is where the "likelihood of confusion" risk lives. A quick search in both stores, plus Google, for names that sound alike, look alike, or mean the same thing in your category gives you a picture of the risk landscape.

This is also where a dedicated tool like IPRightsHub's App Name Checker earns its keep — it runs similarity scoring alongside the basic availability check, so you're not just asking "does this name exist?" but "does something close enough to cause a problem exist?"

The "Driftly" Problem: A Scenario Nobody Talks About

Imagine you pick Driftly for a new mindfulness app. You search the App Store — nothing. You buy driftly.com — available. You spend three months building and designing.

Then:

1. You try to submit to Apple and discover someone reserved Driftly in App Store Connect 47 days ago. They're still in development.
2. A quick USPTO search you skipped at the start would have shown a Class 9 mark for Drift covering mental wellness software — filed 18 months ago.
3. There's an Android app called Driftr with 200k downloads. Not a trademark issue, but a brand confusion issue that will kill your ASO from day one.

None of these would have shown up in a public App Store search. All of them would have shown up in a proper pre-build check that takes one afternoon.

The cost of catching this early? A few hours and maybe a $99 developer account.

The cost of catching it after launch? A forced rebrand. New domain, new handles, new store listing, reset ASO rankings, confused users, and the psychological tax of starting over on something you already shipped.

What "App Store Approval" Does Not Mean

This is worth saying plainly because it catches people every single time:

Getting your app approved on the App Store or Google Play does not give you any trademark rights to your app's name.

Store approval means you passed the platform's content and technical review. That's it. It's a platform permission, not a legal right. A company with a registered trademark in your category can file a complaint with Apple or Google and have your app removed — even if it's been live for a year, even if you have thousands of users.

The only protection that holds up in that scenario is your own registered trademark. Filing takes 8–18 months from application to registration, which means the best time to start is before you launch — not after the C&D arrives.

The Quick Checklist (Save This)

Before you commit to a name and start building:

1. Search publicly — App Store + Google Play + Google. Not conclusive, but eliminates obvious conflicts in 5 minutes.
2. Test in App Store Connect — the only definitive iOS availability check. Requires a developer account.
3. Run a trademark search — USPTO TESS at minimum. Search exact match, phonetic variants, and Class 9.
4. Check domain and social handles — Namechk or KnowEm for a one-pass scan.
5. Reserve your package name — inside Google Play Console, pick it and lock it.
6. Run a similarity scan — search for names that sound or look like yours in your category.

If you pass all six? Build with confidence. If you hit a flag on any of them — assess before you invest.

The name is part of the product. Check it like one.
