Find competitor apps
We find 10 competitor apps from your category, keywords, competitor links or names, websites, and buyer persona.
How it works
We look for the strongest pain and the clearest pull.
Review Radar is built to make app idea selection less vague. It uses public App Store review signal to surface repeated frustration, visible praise, and the narrow version-one opportunity between them.
Read critical signal first
For critical signal, we start with 1-star reviews, then move to 2-star and 3-star reviews only if needed.
Read favorable signal too
For favorable signal, we start with 5-star reviews, then move to 4-star and 3-star reviews only if needed.
Select long substantive reviews
We select the five longest substantive reviews from the first 20 reviews in each active rating bucket.
Shape the MVP angle
We use those 100 selected reviews with your inputs to shape the version-one opportunity.
Write the idea card
The description names the buyer, keeps the best-reviewed behaviors, avoids repeated complaints, defines the V1 focus, and ends with a one-line elevator pitch.
Important caveat
No revenue projections. No fake certainty.
We do not promise revenue or demand. The crawl is designed to reveal review-backed customer pain so you can choose a sharper app direction.
