How to Build an Engaging Community UI for Mobile Apps: 58’s Redesign Insights

In popular apps, a community serves as a rich platform for users with shared interests, needs, or goals to exchange content.

The importance of a community in an app includes defining target users, understanding their needs, providing high‑quality content to attract participation, designing a youthful and engaging UI, encouraging interaction through rewarding activities, and maintaining strong management for healthy growth.

For the 58 app, the community redesign focuses on activating content flow, strengthening content advantages, and presenting a fresh visual style that feels young, topical, and participatory.

The overall design creates a lively atmosphere to showcase diverse community content, using a yellow‑green gradient that aligns with the platform’s color scheme and conveys a youthful vibe.

Live module : A carousel switches every 10 seconds, enlarging the active live room while showing cover images for others; the title area is slightly enlarged to emphasize branding and live content.

Announcement module : Implemented as a drawer that expands when the user scrolls, with a textured background for depth, the title positioned top‑left to save space, and a playful mascot element.

The feed stream is streamlined by removing inner card borders and adjusting spacing to display more content.

New community content reaches users in more scenarios, offering one major announcement and two minor ones for targeted user groups.

Finally, a side‑by‑side comparison highlights the visual and functional improvements of the new community design.

In summary, a well‑designed community adds value for users and expands the app’s growth potential.
