Free App Name Checker – Is It Taken?
Apple approves your code. But if your name infringes a trademark, they will kill your Bundle ID forever.
Building an app takes months of Swift coding, UI design, and backend engineering. But the most fragile part of your stack isn't the server—it's the name. Just because a name appears "available" when you type it into App Store Connect doesn't mean you own it. If you inadvertently infringe on a registered trademark (even one from a non-app company), you risk a sudden "Metadata Rejected" status during review, or worse—a post-launch takedown that freezes your download count and forces a total rebrand of your icon, screenshots, and code signature.
Unlike web apps where you can rebrand overnight, mobile apps are locked to an immutable **Bundle ID** (e.g., `com.company.appname`). Once you publish to the App Store with that identifier, you cannot change it without creating a brand new app and losing all your reviews, ratings, and download history. A naming mistake doesn't just cost you marketing dollars—it orphans your codebase forever.
This App Name Checker searches across the Apple App Store, Google Play Store, and USPTO database simultaneously. It helps you identify conflicts early, so you don't burn your 120-day "New App" boost on a name you can't keep.
Check mobile app name availability across app stores and trademarks.
Important Disclaimer
This scan analyzes app names for similarity with existing apps and trademarks. App store name availability is separate from trademark clearance. High similarity may affect app store approval.

How Our App Name Availability Check Works
Our App Name scanner uses a multi-stage analysis pipeline designed to clear your name for both the stores and the courts:
- 1.**Store-Specific Scalping**: We ping the live registries of both the Apple App Store and Google Play Store. This tells you if the exact name is taken *currently* on either platform (crucial for cross-platform consistency).
- 2.**Trademark Cross-Reference**: Software is uniquely protected in **Class 9** (Downloadable Mobile Apps) and **Class 42** (SaaS / Cloud Services). We scan USPTO records specifically for these classes to see if a non-app company already owns the rights.
- 3.**ASO Keyword Analysis**: A good name is memorable; a bad name is invisible. We flag names that are too generic to rank (e.g., naming your calculator app "Calculator" makes it impossible to own the SEO space).
The entire process completes in seconds, giving you actionable risk signals.
Data Sources & Global Coverage
The App Store is a global marketplace. Your name needs to be safe everywhere.
Our system cross-references data signals from:
- •**Apple App Store**: Live availability checks for iOS/iPadOS apps.
- •**Google Play Store**: Real-time checks for Android availability.
- •**USPTO** (United States Patent and Trademark Office): Federal trademark records for software classes.
- •**WIPO** (World Intellectual Property Organization): International trademark data for global launches.
Note:
We do not partner directly with Apple, Google, or the USPTO. This tool uses open and proprietary data models to estimate risk, serving as a powerful preliminary screening tool.
Interpreting Your App Name Report
*Action*: Register the matching domain and file a trademark immediately.
- •**Available on Stores + USPTO (Green)**: The holy grail. The name is unclaimed on stores and legally clear.
*Action*: Proceed with caution. Inconsistent branding hurts growth. Users might download the wrong app on the other platform.
- •**Taken on One Store (Yellow)**: The name is free on iOS but taken on Android.
*Action*: **STOP.** This is a "trolling" trap. The trademark holder is likely waiting for you to get successful before they sue you for damages.
- •**Trademark Conflict (Red)**: The name is free on stores, but registered at the USPTO.
Pro Tip:
Avoid "Prefix" names. Naming your app "InstaFilter" or "FaceDate" invites lawsuits from Meta (Instagram/Facebook), who aggressively protect their prefixes.
### 📦 The "Bundle ID" Trap: Why Rebranding Kills Apps
Why is picking the right name so critical for mobile apps? Because of the **Bundle ID** (iOS) and **Package Name** (Android).
What It Is
: A reverse-domain identifier like `com.company.zenlist` that uniquely identifies your app in the store ecosystem.
The Problem
: Once you publish an app with a Bundle ID, it is **immutable**. You cannot change it without: • Creating a brand new app listing from scratch • Losing all existing reviews and ratings (resets to 0 stars) • Breaking all deep links, push notification certificates, and API integrations • Abandoning your download count and ranking history
The Nightmare Scenario
: You launch as "ZenTask" (`com.startup.zentask`). You get sued for trademark infringement. You rebrand the *display name* to "FocusTask" to comply with the cease & desist.
The Permanent Scar
: • Your Bundle ID remains `com.startup.zentask` forever • Every crash log still references "zentask" • Your competitors can reverse-engineer your .ipa and see the infringing name embedded in the code • You live with a legal landmine in your app's DNA
The Fix
: Get the name right *before* you set the Bundle ID. That's what this tool is for.
User Scenario: The "$15K Phantom" Disaster
He spent six months building it. Apple said the name was "already used." But it didn't exist anywhere.
A solo developer spent six months building **"FitQuest"**—a gamified fitness tracker with AR workouts. He secured the .com domain, the Instagram handle, and built a waitlist of 5,000 beta users.
Week 24
: He opens App Store Connect to create the app listing and upload his first build.
Error Message
: *"The App Name you entered has already been used."*
He searches the entire App Store. **"FitQuest" doesn't exist anywhere.**
The Issue
: Another developer had created a "placeholder" for FitQuest in their App Store Connect account **3 years ago** but never uploaded code. Apple allows developers to "squat" on names indefinitely by creating empty app shells—visible only to Apple, invisible to the public.
The Fallout
: • Lost his clean branding (had to rename to "FitQuest: Daily Tracker") • Instagram handle no longer matched the app name • Domain name became mismatched • 5,000 waitlist subscribers confused by the rebrand • $15,000 in sunk costs (design, marketing materials, custom icon)
The Hidden Truth
: Apple's "120-day reservation" rule isn't strictly enforced. Phantom squatters can hold names for years by periodically updating metadata without ever shipping.
This tool would have flagged the "Phantom" unavailability instantly by checking Apple's internal registry, not just the public App Store.
Real-World App Store Takedowns
Case 1: "Candy" Crush Saga
King.com trademarked the word "Candy" for games. They successfully issued takedowns against hundreds of apps with "Candy" in the title, forcing indie devs to rename or vanish. *Lesson*: even common words can be owned in specific contexts. [Read about gaming trademarks on our Hub](/hub)
Case 2: The "Paper" Dispute
FiftyThree built a drawing app called "Paper." Facebook launched a news app called "Paper." FiftyThree owned the trademark. Facebook eventually had to shutdown their app (for various reasons, but the naming dispute was a PR disaster). *Lesson*: Big tech companies can't always bully their way to a name. [See startup IP guides on our Hub](/hub)
Case 3: "Flappy Bird" Clones
After Flappy Bird was pulled, thousands of clones appeared. Apple and Google eventually mass-rejected apps with "Flappy" in the title to stop the spam, citing "spam/copycat" policies. *Lesson*: Riding a trend is a short-term strategy.
Common App Naming Mistakes
These errors turn months of development into legal nightmares.
- ❌**"The Store Let Me Submit It"**: App Store Connect only checks for *exact, character-for-character* duplicates. It does not check for "confusingly similar" names, which is the legal standard for infringement.
- ❌**Ignoring Android**: "I'm iOS only." That's fine, but if an Android app with your name has 1M downloads, you will never rank in Google search results.
- ❌**Descriptive Names**: Calling your weather app "Best Weather" is impossible to trademark. You will have zero protection against copycats.
- ❌**Generic Terms**: You cannot trademark "Email" or "Flashlight." You need a distinctive brand (e.g., "Spark Mail").
- ❌**"I'll just add 'App' to the end."**: If "Zenith" is taken, naming yours "Zenith App" is still trademark infringement. It creates "consumer confusion."
- ❌**"I'm an indie dev, nobody will sue me."**: Apple and Google use automated systems. If a rights holder files a form, the bot removes your app. No lawyer required.
- ❌**"I'll optimize for keywords in the name."**: Naming your app "Best To-Do List Daily Planner" will get you rejected for "Metadata Manipulation." Apple wants brand names, not keyword stuffing.
⚠️ **The "Prefix" Lawsuit Magnet**
Apps named **InstaGallery**, **FaceDate**, or **SnapWidget** might get approved initially, then removed 6-12 months later when Meta (Facebook/Instagram/WhatsApp) or Snap Inc. files an aggressive complaint.
Why?
These companies own common-law rights to the **"Insta,"** **"Face,"** and **"Snap"** prefixes in social networking and photo sharing categories. Even if your app does something different, they argue the prefix creates "consumer confusion" about affiliation.
The Fix
: Avoid using any established social media brand prefix unless you want a legal fight you cannot win.
Class 9 vs Class 42 (The Software Confusion)
Software trademarks are tricky because they span two main classes:
- •**Class 9 (Products)**: Downloadable software, mobile apps, code that lives on a device. (e.g., Microsoft Word 2010).
- •**Class 42 (Services)**: SaaS, Cloud computing, "Software as a Service." (e.g., Office 365).
Most modern apps need protection in **both**. If you only check Class 9, you might miss a massive SaaS competitor in Class 42 who can still block you.

Free vs. Professional IP Protection
Use This Free Tool When:
• You are iterating on app ideas • You want to check availability across iOS and Android instantly • You are an indie developer with a limited budget
Escalate to a Professional When:
• You are VC-backed or have significant investment • You plan to launch globally (App Store regions vary) • You found a conflict in Class 42 and aren't sure if it covers you
### 🚀 The "ASO" Playbook: How to Name for Downloads
Don't just name for legality—name for discoverability. Most developers make one of two mistakes:
Mistake #1
: Pure brand name with no keywords → "Calm" • Pro: Trademarkable, memorable • Con: Zero organic search traffic until you're famous
Mistake #2
: Keyword-stuffed spam → "Best To-Do List Daily Planner Pro" • Pro: Ranks for keywords • Con: Gets rejected by Apple for "Metadata Manipulation"
The Winning Formula
: Use a **3-part structure** to satisfy the lawyers, the algorithm, and the user:
- 1.**The Brand** (Legal Layer):
- .• Example: `Calm`
- .• Why: Short, trademarkable, fits under your app icon without truncation
- 2.**The Separator** (ASO Layer):
- .• Use a colon (`:`) or em dash (`—`)
- .• Why: Apple and Google allow subtitle keywords after a separator
- 3.**The Keywords** (Discovery Layer):
- .• Example: `Sleep & Meditation`
- .• Why: You rank for "sleep app" and "meditation app" without keyword stuffing
Full Title
: `Calm: Sleep & Meditation`
Result
: • You trademark "Calm" (legal protection) • You rank for "sleep" and "meditation" (organic growth) • You avoid rejection for spam (compliance)
This is the only safe way to do both.
Best Practices for App Naming
Staying compliant and discoverable requires strategy.
- 1.**Unique Spelling**: Using "Lyft" instead of "Lift" helps, but it's still phonetically risky. Try to invent a word (*Spotify*).
- 2.**Short & Sweet**: App icons have labels. Names longer than 11 characters get truncated ("My Awesome A...").
- 3.**Reserve Immediately**: Once you find a safe name, create the "placeholder" app in App Store Connect to lock it for 120 days.
- 4.**Social Match**: Ensure you can get the @handle for support and marketing before you commit.
Frequently Asked Questions (FAQ)
Q: Does Apple check trademarks during review?
A: No. Apple's review process focuses on functionality, safety, and content guidelines. They do *not* perform a trademark search. They operate on a "notice and takedown" basis.
Q: Can I use "Insta", "Chat", or "Face" in my name?
A: It is highly risky. Companies like Meta (Facebook/Instagram) and Snap Inc. aggressively defend their brand prefixes. Using "Insta" implies an affiliation that doesn't exist.
Q: What if the .com is taken but the .io is free?
A: For apps, the domain matters less than the store name. However, owning the ".com" adds credibility. Many apps survive with ".io" or ".app" domains successfully.
Q: Can I change my app name later?
A: You *can*, but it destroys your ASO (App Store Optimization). You lose your keyword ranking, your word-of-mouth recognition, and potentially your user reviews.
Q: Can I use the same name as a board game?
A: Maybe. Trademarks are class-specific. However, many board games (Class 28) also register in Class 9 (Video Games). Monopoly would definitely sue you.
Q: Why does the App Store say the name is taken but I can't find it?
A: A developer might have created the "placeholder" for the app in App Store Connect but hasn't published it yet. Placeholders last for 120 days.
Q: Do I need to be an LLC to put an app on the store?
A: No, you can publish as an individual. However, naming your developer account the same as your app adds professional credibility.
Q: Can I use emojis in my app name?
A: No. Apple and Google generally reject special characters and emojis in the official app title metadata.
Q: Is my code copyrighted automatically?
A: Yes, the moment you write it. But the *name* is not. That requires a trademark.
Q: What if I have a trademark but Apple rejects my name?
A: Apple has its own "App Store Review Guidelines." Even if you own the trademark, if your name is offensive or misleading (e.g., "Free Virus Cleaner"), they will reject it.
Q: Can I buy a name from another developer?
A: Yes. You can "transfer" an app between developer accounts. This is a common way to acquire a name that is already taken (often involves buying the code/asset).
Q: Does this tool check the Mac App Store?
A: We differentiate between iOS and Mac stores where possible, but availability usually tracks together. If it's taken on iOS, you probably can't use it on Mac either.
Q: Can I use TestFlight to "reserve" a Bundle ID before my app is ready?
A: Yes. Creating an app in App Store Connect and uploading a single TestFlight build (even if it's just a "Hello World" placeholder) reserves your Bundle ID and app name for 120 days. Many developers do this to lock a name while still coding. **Pro tip**: You must upload a new build every 120 days or the reservation expires.
Q: What happens if my app name is rejected but my Bundle ID is already set?
A: You're partially stuck. Apple may let you change the *display name* (what users see in the App Store), but your Bundle ID remains permanent. This creates the "ZenTask/FocusTask" mismatch problem. Always get name approval *before* finalizing your Bundle ID.
Q: Does changing my app name affect my App Store URL?
A: Yes and no. Your app's URL is based on your **Apple ID** (a unique number like `id123456789`), not your name. So `apps.apple.com/app/id123456789` stays the same. However, your app's *vanity slug* (e.g., `/zenlist/id123456789`) can update when you change the display name. Old links may break, hurting your SEO.
Common Questions About App Names
Q: Apple or Google approved my app. Doesn't that clear the name?
A: No. App review checks content and technical guidelines, not trademarks. Rights holders file takedown complaints after launch, and both stores' developer agreements let them remove your app while you absorb the loss.
Q: Can two apps share the same name?
A: Stores require exact names to be unique, but confusingly similar names coexist until someone complains. Subtitles, keywords, and icons all feed a confusion analysis, so "close but different" is not a strategy.
Q: Which trademark classes cover apps?
A: Class 9 covers downloadable software and Class 42 covers software as a service. Depending on what the app does, Class 35 (commerce) or 41 (education and entertainment) may also apply.
Next Steps: Ship Your App
Name looks safe? Here is your pre-launch checklist:
- •**Reserve the Handle**: Create the "placeholder" app in App Store Connect to lock the name for 120 days.
- •**Check the Domain**: Use our **[Domain Name Checker](/scan/domain-name)** to see if the web URL is free.
- •**Draft Your Standard Terms**: Use a legal generator for your Privacy Policy and EULA (required by Apple).
