See why users love or leave any app or game
OneStar reads App Store, Google Play and Steam reviews and shows what users love, why they leave and what they ask for, with the reviews behind every number. Research a market: report on any app or game free, or compare up to four on Pro. Listen to your own users: connect App Store Connect to read every review, see what changed after a release and which bad reviews still need a reply. Built on Jev, which asks every review the same questions.
OneStar analyzes user reviews from App Store, Google Play, and Steam to identify key factors influencing user retention and satisfaction. It offers market research capabilities and allows developers to monitor their own app reviews for insights on user feedback and response effectiveness.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
