Social features are the capabilities inside an app that let users interact with each other rather than only with the product, such as profiles, social feeds, comments, groups, and in-app chat.
What are Social Features?
In practice, teams scope social features around whichever interaction pattern fits their product: a fitness app might add only a feed and reactions, while a marketplace might add direct chat and group threads without ever building a public profile page. Most products introduce these capabilities incrementally, starting with lightweight identity and content features such as profiles and comments before layering on heavier real-time ones such as chat and live streaming once there is an active user base to support them. The term is sometimes used loosely to mean any user-generated content feature, but the defining trait is user-to-user interaction: a star rating or a wishlist is user-generated content, not a social feature, because it does not connect one user to another. A common variant is "social layer," used when these features are added on top of an existing non-social app rather than built into the product from day one.
Why Social Features Matter
An app without social features is a single-player product: the user opens it, completes a task, and leaves. Social features add a second reason to return, which is other people. For a product team, this changes the retention question from "how do we remind users to come back" to "how do we give users something new to see every time they open the app". For a growth team, social features turn existing users into a distribution channel, since users who post, invite, or share bring in others. The measurable effect shows up in session frequency, session length, and the share of users who come back after week one.
Types of Social Features
| Type | Examples | Primary effect |
|---|---|---|
| Identity | Profiles, avatars, follow and follower lists | Users recognize each other and build reputation |
| Content | Feeds, posts, comments, reactions, polls | Users create the material that brings others back |
| Groups | Communities, channels, membership, roles | Users organize around shared interests |
| Messaging | One-to-one chat, group chat, mentions | Users hold private and semi-private conversations |
| Live | Live streaming, live chat, stories | Users gather around events in real time |
| Trust and safety | Moderation, reporting, blocking, content filters | Users feel safe enough to participate |
Worked example of the effect on usage: an app with 100,000 monthly active users and an average of 3 sessions per user per month adds a feed and comments. If 20% of users become active contributors and each contributor's posts prompt other users to return once more per month, monthly sessions rise from 300,000 to roughly 380,000 with no change in the user count. Active contributors typically make up 10-30% of a healthy user base, and that minority drives most of the additional sessions.
Social Features and social.plus
social.plus provides the engagement infrastructure that brands use to add social features to their own apps without building the backend, real-time delivery, and moderation systems from scratch. The product covers feeds, groups, chat, live streaming, stories, profiles, and moderation, delivered through Social SDKs, APIs, and a UIKit so that the features sit inside the brand's own app rather than on a third-party network. Brands using social.plus report engagement rates of 20-50% and retention lifts of 10-35%. Harley-Davidson runs an in-app community of more than 1M members on this basis, and Noom's community layer reaches 45M+ users.
Key Takeaways
- Social features are the parts of an app where users interact with each other, not just with the product.
- They group into identity, content, groups, messaging, live, and trust and safety, and most apps grow through these in stages.
- The commercial effect is more frequent return visits driven by a minority of active contributors, typically 10-30% of users.
- Building these features in-house means owning real-time delivery, storage, and moderation; engagement infrastructure removes that scope.
