Collision Radar

Before you spend weeks building your app, find out what already exists.

Collision Radar takes a plain description of your app idea and searches the App Store and Google Play for the most similar apps already published. You get raw comparison data: names, developers, categories, store links, and a semantic similarity score for each match, plus a minimum estimate of how many similar apps exist in total.

WHY IT MATTERS
Hundreds of thousands of new apps are submitted every year, and store review teams increasingly reject apps that duplicate what is already widely available. Knowing the landscape before you build helps you differentiate early, or move on to a better idea before sinking time into a crowded one.

HOW IT WORKS
1. Describe your idea in a few sentences.
2. Choose the target store: App Store or Google Play.
3. Get the top 30 most similar existing apps, ranked by semantic similarity, in seconds.

The analysis goes beyond keyword matching. Collision Radar compares the meaning of descriptions using multilingual language analysis, so it finds functional overlap even when the wording differs.

PRIVATE BY DESIGN
Your ideas are never stored. Descriptions are processed in memory and discarded. No account, no email, no tracking, no ads. The app uses an anonymous identifier generated on your device, and nothing else.

HONEST DATA, NOT VERDICTS
Collision Radar does not predict store review outcomes and does not tell you whether your app will be approved. It shows you what exists, so you can decide for yourself how to stand out.
