For App Developers
Your users are telling you what to fix. Are you listening?
Unstar collects and analyzes the 1-3 star reviews of any iOS or Android app. If your app is listed here, you can turn those complaints into a prioritized fix list, reply to reviewers in seconds, and get alerted before a bad update tanks your rating.
