Apple allows one app per name
You find out the name is taken when App Store Connect refuses it, after the logo and the domain are bought.
Use cases · App name check
Is your app name free? Check both stores and the domains in one question
Before you fall in love with a name, ask. Builders HQ searches the App Store and Google Play for the exact name, names that start with it and similar ones, checks the likely Android package ids and the domains, and gives each name a verdict.

check_app_name with names: ["Snapfolio", "Notely", "Trailmix"], country: "US".The same answer as text
You ask: Are these app names free: Snapfolio, Notely, Trailmix?
| Name | Verdict | Who has it | .com |
|---|---|---|---|
| Snapfolio | used | SnapFolio: Portfolio Tracker (App Store), SnapFolio (Play, 10+ installs) | registered |
| Notely | used | Notely – Notes & PDF app (App Store), Notely (Play, 10,000+ installs) | registered |
| Trailmix | used | TrailMix: Step to the Beat, Trailmix: Discover Plan Track (App Store) | registered |
Your assistant: None of the three is clear: small apps already use each name on the stores and every .com is registered. You could still publish with a longer title, but people searching the name would find them first.
Why it is hard today
Search is per store and per country
Checking two stores, ten candidate names and three domains is sixty searches.
"Free" is not enough
A name can be legally free and still useless if a big app fills the search results for it.
How it works
- Add Builders HQ to your assistant and sign in.
- Give it up to ten candidate names, and the country if it is not the US.
- Read the verdict for each (taken, avoid, used, crowded, similar or free) with the apps and domains behind it.
Prompts to try
- Are these app names free: Snapfolio, Notely, Trailmix? Check .com and .app too.
- Give me 20 names for a habit tracker, then check which are free on both stores.
- Who are the top habit tracker apps on the App Store and Google Play, and how many ratings do they have?
- Is com.trailmix.app already used on Google Play?

Questions
Which stores and countries does it check?
Apple's App Store and Google Play, in the store country you choose (the US by default).
Does it see names reserved but not released?
No. It sees live apps only; a name someone reserved in App Store Connect but never released shows only there.
Which domains does it check?
.com, .app and .ai by default, or up to six endings you choose, through public registration data (RDAP).
