Unlike basic review aggregators that only show star ratings or word clouds, NeedRadar uses LLMs to deeply understand pain points, feature requests, and intent from hundreds of thousands of app reviews. It covers not just App Store and Google Play, but also Chinese stores like Huawei, Xiaomi, vivo, OPPO, Coolapk, and TapTap. Each opportunity gets an ROI score based on frequency × severity × user value × competitor gap.
