“Has someone already built this?” is usually the first question a founder asks about a new app idea, and usually the one answered the laziest — a quick search of the App Store, a glance at the top three results, and a decision made either way. That search misses more than it finds: apps ranking on different keywords, apps positioned under a completely different name, apps live on one platform but not the other. Here's a more complete version of that check.
- Search both app stores with several different phrasings of the problem, not just your working app name.
- Check what's ranking for the underlying keywords, not just an exact-name search.
- Look past the app stores — Google search results and community discussion surface competitors that never show up in a store search.
- Competition isn't automatically a no — read what existing apps' users complain about before deciding.
Step 1: Search both stores, several ways
Start with the obvious search, but don't stop there. Search the problem your app solves, not just the name you've been calling it in your head — a habit tracker might also be findable under “streak app,” “daily routine,” or “discipline tracker.” Run every phrasing on both the App Store and Google Play separately; it's common for a category to be crowded on one platform and wide open on the other.
Step 2: Check who actually ranks for the keyword, not just who exists
An app existing and an app being findable are different problems. Plenty of “competitors” technically exist but rank on page three for every relevant term — functionally invisible to a real user searching the way your future customers will. The apps worth worrying about are the ones actually occupying the top results for the keywords your idea depends on.
The Keyword & ASO module estimates which terms an app is realistically positioned to rank for, so you can see whether the keywords your idea needs are already owned by someone who ranks well, or genuinely open.
Step 3: Look past the app stores
Some of the most direct competition never shows up in a store search at all — a web app with no native listing, a feature bolted onto a bigger platform, or a tool that's well known in a specific community but invisible to a generic keyword search. A plain Google search for the problem you're solving, plus a scan of relevant forums or subreddits, surfaces competitors that an app-store-only search will always miss.
The Search Analysis module pulls real Google search results for an app — classified by source, sentiment, and topic — so you can see how it's actually discussed and discovered outside the app stores, not just how it's listed inside them.
Step 4: Read what existing users are unhappy about
Finding competition isn't the end of the check — it's the start of a better one. If an app in your space already exists, its one- and two-star reviews are the most honest market research available: they tell you exactly what current users wish it did differently, which is often a more reliable starting point than a from-scratch idea. “Someone already built this” and “someone already built this well” are very different findings.
The App Reviews module reads up to the last 50 real reviews per store and summarizes recurring advantages and disadvantages with real example quotes — so you can see exactly where an existing competitor is falling short.
Competition isn't automatically a “no”
A crowded category with clearly frustrated users is often a better signal than an empty one — an empty category can mean nobody wants it, and a crowded one with bad reviews means demand is proven but unmet. The point of this check was never “does anyone else exist,” it's “is there still a real gap.” Once you have both answers, the last piece is turning it into an actual go/no-go decision:
