How to Choose the Perfect App Name (+ AI Generator)

Your App Name Is Your First Impression

Choosing an app name might seem straightforward, but it is one of the most consequential decisions you will make as an app developer. Your name appears everywhere — the App Store, Google Play, the home screen, notification banners, word-of-mouth conversations, and social media mentions. It shapes user expectations, affects search discoverability, and defines your brand from the moment someone encounters it.

A great app name is memorable, easy to spell, easy to pronounce, available as a domain and social handle, and — critically — it helps your app rank for relevant keywords. A poor name can limit your growth no matter how good the product is.

In this guide, we will walk through proven naming strategies, platform-specific constraints, trademark considerations, and methods for testing name candidates. Plus, we will show you how AI-powered name generators can shortcut the brainstorming process.

Platform Character Limits

Before brainstorming, know the constraints:

Platform	Field	Limit	Indexed for Search
Apple App Store	App Name	30 characters	Yes
Apple App Store	Subtitle	30 characters	Yes
Google Play	App Title	30 characters	Yes
Google Play	Short Description	80 characters	Yes

The 30-character limit is important. Your brand name and descriptive keywords must fit within this space. A common pattern is: BrandName — Keyword Phrase (e.g., "Calm — Sleep & Meditation" or "Duolingo — Language Lessons").

If your brand name alone takes up 20 characters, you only have 10 characters left for keywords (including the separator). Plan accordingly.

7 Naming Strategies That Work

1. Descriptive Names

Descriptive names tell the user exactly what the app does. Examples: "Sleep Tracker," "Budget Planner," "Photo Editor." These names have high keyword value because they match what users search for, but they can feel generic and are harder to trademark.

Best for: Utility apps in crowded categories where discoverability matters more than brand identity.

2. Invented Words

Completely made-up words that sound good and are easy to remember. Examples: Spotify, Zillow, Venmo, Hulu. These are highly brandable and easy to trademark, but they carry zero inherent meaning — you need marketing to establish what the brand stands for.

Best for: Apps with strong marketing budgets or viral potential where the brand will become synonymous with the category.

3. Compound Words

Combining two real words into a new word. Examples: Facebook, Snapchat, Evernote, Airbnb. These are memorable, often somewhat descriptive, and generally trademarkable.

Best for: Apps that want to balance brandability with a hint of what the app does.

4. Modified Spellings

Taking a real word and altering the spelling. Examples: Lyft (lift), Fiverr (fiver), Tumblr (tumbler). These are attention-grabbing and trademarkable but can cause confusion with spelling and verbal communication ("It is Lyft with a Y").

Best for: Apps targeting younger audiences or categories where a playful brand fits.

5. Metaphorical Names

Using a word from a different context to evoke a feeling or concept. Examples: Apple (technology), Slack (communication), Kindle (reading). These are distinctive and memorable, carrying emotional associations without being literal.

Best for: Apps aiming for strong emotional branding and differentiation.

6. Acronyms and Abbreviations

Shortened versions of longer names. Examples: HBO, VSCO, IMDb. These are concise but can be harder to remember and often require the full name to be established first.

Best for: Apps with long descriptive names that need a shorter version for daily use. Generally not recommended for new apps without existing brand recognition.

7. Personal or Character Names

Using a person's name or a character name. Examples: Alexa, Siri, Cortana, Oscar. These humanize the product and work especially well for AI assistants, chatbots, and service-oriented apps.

Best for: AI-powered apps, personal assistant apps, or apps that benefit from a human-like personality.

What Makes a Name "Good"?

Regardless of the strategy you choose, a strong app name shares these qualities:

Easy to spell: Users need to type it into a search bar. If they cannot spell it, they cannot find it.
Easy to pronounce: Word of mouth is still a powerful growth channel. If people cannot say your name confidently, they will not recommend it.
Memorable: After hearing or seeing it once, users should be able to recall it. Short names (1-2 words, under 12 characters) tend to be more memorable.
Available: The name must be available in the App Store and Google Play, as a domain name (or close variant), and ideally on major social media platforms.
Not trademarked: Using a trademarked name will lead to legal issues and forced rebranding. Check before you commit.
Keyword-compatible: The name should leave room in the 30-character title to include a descriptive keyword phrase for ASO.

Trademark Considerations

Trademark issues can force a painful rebranding after launch. Protect yourself by following these steps:

Step 1: Search the USPTO (United States Patent and Trademark Office)

Use the TESS (Trademark Electronic Search System) at the USPTO website to search for existing trademarks. Look for exact matches and similar names in the software/mobile app categories (International Classes 9 and 42).

Step 2: Search International Databases

If you plan to distribute internationally, search the EUIPO (European Union), WIPO Global Brand Database, and relevant national trademark databases.

Step 3: Check the App Stores

Search both the App Store and Google Play for your proposed name. Even if a name is not formally trademarked, an existing app with the same name can cause confusion and app store policy issues.

Step 4: Check Domain and Social Media Availability

Use domain registrars and social handle checkers to verify availability. You do not necessarily need an exact .com match, but having a related domain and consistent social handles strengthens your brand.

Step 5: Consider Registering Your Own Trademark

Once you have settled on a name, consider filing a trademark application. It is an investment (a few hundred dollars for a basic filing in the US), but it provides legal protection and prevents others from using your name.

Testing Your Name Candidates

Do not commit to a name based on gut feeling alone. Test it with these methods:

The Phone Test

Call a friend and say: "I built an app called [name]." Ask them to text it back to you. If they spell it wrong, reconsider the name.

The Crowded Bar Test

Imagine telling someone your app's name in a noisy environment. Would they understand it? Would they remember it five minutes later?

Survey Testing

Create a simple survey with 3-5 name candidates and show them to people in your target audience. Ask which names sound most appealing, which they would be most likely to download, and what they think each name represents.

Search Volume Testing

If one of your candidates includes a high-volume keyword (e.g., "budget" or "fitness"), check the search volume using ASO tools. A name with built-in search volume has a discoverability advantage from day one.

Social Media Reaction

Post your top candidates on relevant forums, social media groups, or communities like Reddit or Indie Hackers. Real reactions from potential users can reveal issues you did not anticipate.

Using AI to Generate App Name Ideas

Coming up with a great name is hard. You are essentially trying to find one or two words that are memorable, descriptive, brandable, available, and legally safe. AI-powered name generators can dramatically speed up this process.

Appilot's app name generator uses AI to suggest unique, relevant names based on your app's description, category, and target audience. Here is how it works:

Describe your app: Tell Appilot what your app does, who it is for, and what makes it unique.
Set your preferences: Choose naming styles (descriptive, invented, compound, etc.) and any words you want to include or exclude.
Get suggestions: Appilot generates dozens of name options, each with domain availability and keyword relevance indicators.
Refine and iterate: Pick your favorites, request variations, and narrow down to your final candidates.

The advantage of using an AI generator is volume: instead of brainstorming a handful of names, you can evaluate dozens or hundreds of options in minutes. This dramatically increases your chances of finding a name that checks every box.

Even better, Appilot lets you generate your app name alongside your icon design and ASO-optimized description in a single workflow. This means your name, icon, and store listing are designed to work together as a cohesive brand from the start.

Common Naming Mistakes

1. Choosing a Name That Is Too Long

If your brand name takes up most of the 30-character title, you have no room for keywords. Keep your brand name short (ideally under 12 characters) to leave room for descriptive terms.

2. Using Special Characters or Numbers

Names with numbers (e.g., "Fit2Go") or special characters can be confusing to spell and remember. They also look less professional in most cases.

3. Picking a Name That Is Too Similar to a Competitor

If users confuse your app with a competitor, you lose downloads and potentially face legal action. Differentiation matters.

4. Ignoring International Implications

A name that works perfectly in English might have an unfortunate meaning in another language. If you plan to launch globally, check your name in your top target markets.

5. Falling in Love With One Name Before Checking Availability

Always check trademark databases, domain availability, app store listings, and social media handles before emotionally committing to a name. It is much easier to pivot during brainstorming than after launch.

6. Making It Up Based on What Sounds Cool

A name that sounds cool to you might not resonate with your target audience. Always validate with real users from your target demographic.

App Name Checklist

Before finalizing your app name, run through this checklist:

Is it under 12-15 characters (leaving room for keywords in the 30-char title)?
Is it easy to spell after hearing it once?
Is it easy to pronounce?
Does it hint at what the app does (or is it brandable enough to stand alone)?
Is it available in the App Store and Google Play?
Is a matching or closely related domain available?
Is it available on key social media platforms?
Is it free of existing trademarks in your category?
Does it work internationally (no negative meanings in other languages)?
Did real users react positively when you tested it?

Conclusion

Your app name is a strategic asset, not just a label. It influences discoverability through search, shapes user expectations, and defines your brand. Take the time to choose it carefully — or let an AI-powered tool like Appilot help you explore options faster than you could on your own.

The best app names balance brandability with keyword relevance, are easy to spell and pronounce, and are legally safe. Start brainstorming early, test rigorously, and do not commit until you have checked every box. A strong name gives your app a head start that no amount of marketing can easily replicate.
