发现页 (fāxiànyè): Discover page (in an app)

发现页 is a near-universal Chinese-app navigation tab. In 微信 (WeChat) it's the second tab and houses 朋友圈 (Moments), 视频号 (Channels), 直播 (Live), and Mini Programs. In 小红书 and 抖音 it's the algorithm-driven explore feed. Translating UI mockups into Chinese? Designers will expect this exact term.
