How to build social feeds in a mobile app
To build social feeds in a mobile app, teams implement a feed system that displays user-generated content such as posts, updates, comments, or events in a continuously updating stream. Most mobile teams use a social feed SDK or API to handle feed generation, performance, permissions, and scalability instead of building custom feed infrastructure from scratch.
What a social feed is in a mobile app
A social feed is a core interface that surfaces activity from users or communities inside a mobile app. It enables discovery, interaction, and repeat engagement.
Common social feed content includes:
- User posts or updates
- Comments and replies
- Likes or reactions
- Community announcements
- System-generated events such as achievements
Social feeds are foundational to community, collaboration, and engagement-focused mobile apps.
Why social feeds matter in mobile apps
Social feeds create ongoing reasons for users to open the app and interact with others.
Key benefits include:
- Higher session frequency
- Increased time spent in app
- Faster content discovery
- Social proof that encourages participation
- Stronger retention loops
Apps that add social features such as feeds see higher retention compared to apps without them.
Types of social feeds used in mobile apps
Different feed types support different product goals. Many mobile apps use more than one.
Common social feed types
| Feed type | What it shows | Why it matters | Recommended action |
|---|
| Global feed | All public posts | Maximizes discovery | Use for early-stage apps |
| Personalized feed | Content based on follows or interests | Improves relevance | Add after usage patterns emerge |
| Community or group feed | Posts within a group | Keeps conversations focused | Default for private communities |
| Notification feed | Mentions and direct actions | Drives re-engagement | Pair with push notifications |
Core components of a mobile social feed system
Building a social feed requires more than rendering a list of posts.
Essential feed components
| Component | What it does | Why it matters | Recommended action |
|---|
| Event ingestion | Captures user actions | Powers feed content | Standardize event formats |
| Feed generation | Aggregates content | Determines what users see | Start with simple logic |
| Sorting or ranking | Orders feed items | Impacts engagement | Begin with chronological order |
| Permissions | Controls visibility | Protects privacy | Enforce rules at ingestion |
| Moderation | Manages abuse and spam | Maintains trust | Enable reporting at launch |
| Analytics | Tracks feed usage | Measures success | Monitor scroll and interaction |
Build from scratch vs using a feed SDK
Social feeds require high performance, real-time updates, and scalability across mobile devices.
Approach comparison
| Approach | Time to launch | Maintenance effort | Best fit |
|---|
| Custom-built feed | 4 to 8 months | High | Large teams with unique ranking needs |
| Social feed SDK or API | Weeks | Low to moderate | Most mobile apps |
Using a feed SDK reduces complexity around fan-out, caching, and performance optimization.
How social feed SDKs work in mobile apps
A social feed SDK provides backend services and mobile-ready components.
Typical implementation flow:
- User or system actions generate events
- SDK ingests and stores feed events
- Feeds are generated per user or group
- Sorting or ranking logic is applied
- Permissions and moderation rules are enforced
- Feed items are delivered to mobile UI
- Analytics track impressions and interactions
This ensures consistent performance across iOS and Android.

Step-by-step approach to building social feeds in mobile apps
A phased rollout improves stability and adoption.
- Define the feed purpose
Decide whether the feed supports discovery, community, or collaboration.
- Choose the initial feed type
Most apps start with a simple chronological feed.
- Define feed events
Identify which actions appear in the feed.
- Integrate the SDK or APIs
Connect events to feed generation.
- Configure permissions and moderation
Ensure users only see appropriate content.
- Launch and iterate
Adjust feed logic based on engagement data.
Metrics to track for mobile social feeds
Measuring feed performance ensures it delivers business value.
| Metric | Typical range | Why it matters | Optimization action |
|---|
| Feed engagement rate | 20% to 50% | Indicates relevance | Improve content prompts |
| Items viewed per session | 5 to 20 | Shows discovery depth | Optimize ordering |
| Interaction rate | 5% to 15% | Measures participation | Add reactions or replies |
| Retention lift | 10% to 35% | Demonstrates impact | Surface feed earlier |
FAQs
What is a social feed in a mobile app?
A social feed is a stream of user or system-generated updates that users can scroll, interact with, and respond to inside a mobile app.
Should mobile social feeds be chronological or ranked?
Most mobile apps start with chronological feeds and introduce ranking once sufficient engagement data is available.
Do social feeds need real-time updates?
Near real-time updates are sufficient for most mobile apps and help reduce complexity and battery usage.
Can social feeds be monetized in mobile apps?
Yes. Social feeds can support promoted posts, premium visibility, or engagement-based upgrades using platforms like social.plus.
Conclusion
Social feeds are a foundational feature for mobile apps that aim to drive engagement, discovery, and retention. By using social feed SDKs and APIs instead of building custom systems, mobile teams can launch faster while ensuring scalability, moderation, and analytics are handled correctly. Platforms such as social.plus provide the infrastructure needed to build high-performance social feeds directly into mobile apps while maintaining full control over user experience and data.
