App name checker for the App Store & Google Play

App name availability is the question of whether the name you want is already used by a live app, or by something close enough to cause confusion, in the stores and markets you plan to launch in. It is not a single global yes or no. The App Store treats every country as its own catalog, so a name can be completely free in the United States and already claimed in Germany, Japan, or Brazil. Google Play adds another separate layer, with its own listings and its own crowded keywords.

Because of that, the real answer is always regional and always about degree. A name might be clear in nine of your ten target markets, share an exact match in one, and sit next to a handful of similar names in a few more. Understanding that shape, rather than a flat available or taken, is what lets you make a confident naming decision instead of a hopeful guess.

checkappnames queries live storefront listing data and compares each result against the name you enter. It does this in two ways. First it looks for exact matches after normalizing the text, so differences in capitalization, spacing, accents, and punctuation do not hide a real conflict. A listing like "Cafe Mate" is compared fairly against "CafeMate" and "Café-Mate".

Second, it looks for similar names by measuring how much wording two titles share. This catches reworded, reordered, or lightly modified variants that a plain search box would miss, and flags them as possible matches worth a closer look. Every result is grouped by storefront, so you can separate conflicts in your launch markets from noise in countries you will never enter. A full scan runs this across 44 App Store storefronts and Google Play in a single pass.

Most teams validate a name only in their home market, then discover a conflict later when they expand or start paid acquisition abroad. By that point the name is baked into the icon, the screenshots, the landing page, and months of keyword history, so changing it is expensive and disruptive. Checking every target market up front turns a costly late surprise into a cheap early decision.

Weighing conflicts by where your users and revenue will actually come from is the practical part. An exact match in your primary launch country is a serious problem. A similar name in a market you are not targeting for years may be an acceptable risk. Seeing the full country breakdown lets you make that call deliberately, with the data in front of you rather than after the fact.

A store check tells you what is already published; it does not tell you who holds legal rights to a name. Trademarks are registered within specific classes of goods and services and within specific countries, so a name can be unused in the stores and still protected by a registered mark. Treat a clean availability result as a strong early signal, not a legal guarantee.

The most efficient workflow uses both checks in order. Run the store scan first to filter out names that already collide with live apps, then reserve formal trademark research for the shortlist that survives. That keeps legal costs focused on realistic candidates and stops you from investing in a name that was never going to work. For anything high-stakes, confirm with a qualified trademark professional in your target countries.
