How Primocys designed and developed a full-featured social media app combining photo and video feeds, real-time live streaming, PK battles and virtual gift sending — with an engagement-based feed ranking system, multi-language support and Flutter-based delivery for iOS and Android.
Dapke was planned as a single social platform where persistent content and real-time creator experiences could live together. Instead of separating feed activity, live sessions and creator monetization into disconnected products, the platform brings them into one mobile experience supported by a shared backend and admin system.
Photo, text, and short-video posting with stories, likes, comments, and shares — the Instagram-style foundation that keeps daily users engaged.
Real-time live broadcasting with split-screen PK battles — two creators competing for viewer-driven gift support on a live scoreboard.
Viewers purchase coins and send animated virtual gifts during live streams and on posts — the core monetization loop for creators and the platform.
An algorithm-driven feed personalised per user, backed by secure S3 media storage, verified user badges, and content protection at every layer.
Dapke was built around one connected social loop: users discover content, follow creators, join live sessions, interact through gifts, and return to social content without feeling like they switched products.
The delivery brought together the product experience and the systems behind it—from Flutter mobile apps and backend services to real-time communication, streaming, monetization, ranking, media infrastructure, and admin tools.
User flows, social interaction patterns, live engagement and creator journeys.
Cross-platform application delivery for iOS and Android.
Core application logic, user services, content and transaction APIs.
Socket-based chat and events alongside audio and video calling.
Broadcasting, playback, battle state and live interaction workflows.
Virtual currency, gifts, transaction records and platform controls.
Engagement-based scoring for mixed social content.
Verification, moderation, gift controls, notifications and analytics.
Object storage, CDN delivery and supporting media services.
Live streaming app development combines real-time infrastructure, AI systems, and consumer-grade UX into a single product. Each layer creates compounding complexity. Here’s what we solved on Dapke.
Two simultaneous live streams need frame-accurate split-screen sync, a shared gift-scoring timer, and instant scoreboard updates visible to thousands of concurrent viewers without lag or drift between the two broadcasts.
Coin purchases, gift animations, and real-time creator earnings had to process instantly during high-traffic live moments — with zero double-charging, accurate commission splits, and animation rendering that doesn’t tank stream performance.
Building a feed algorithm that ranks photos, text posts, and short videos together — three different content formats — required a unified engagement-scoring model rather than three separate ranking systems.
Dapke separates user-facing app logic, backend services, real-time events, live media delivery, ranking, data storage and administration so each concern can be operated and changed without forcing every feature through one monolithic path.
iOS & Android UI, feeds, profiles, live entry points, messaging and wallet experiences.
Node.js APIs, Socket.io events, authentication, content logic, transactions and session state.
PostgreSQL, Redis, S3/CloudFront, streaming pipeline, ranking services and push delivery.
The feature set was designed around one continuous social loop: discover content, build creator relationships, join live sessions, interact in real time and participate in the gift economy. The product also includes the communication and administration capabilities needed to support those experiences.
A scrollable feed for photo, text and short-video posts, with likes, comments and follows to keep people discovering and engaging with content daily.
Time-limited creator updates that sit alongside the persistent feed, giving people a quick, casual way to share moments without cluttering their main profile.
Creators broadcast in real time with live chat, gift events and audience participation built in, turning every stream into an interactive, shared experience.
Competitive live sessions between creators, complete with real-time battle state, gift-based scoring and public results that keep viewers invested until the end.
A full virtual currency system with animated gifts, transaction records and creator earning logic, so every purchase turns into a meaningful, visible moment.
An engagement-based ranking layer that orders content using signals like interaction, creator affinity and recency, so people see what actually matters to them.
Private, real-time messaging paired with native audio and video calling, keeping every conversation and connection inside the app instead of switching elsewhere.
A verification system paired with configurable leaderboards for creator and gifting activity, adding real trust signals and a reason to keep coming back.
Product UI, metadata and notification handling built for multiple languages from day one, so the platform feels native to every community it reaches.
Dapke’s UX is designed around a single loop: discover content → follow creators → join a live stream → send a gift → earn or spend coins. Every screen is optimised to keep users in this loop as frictionlessly as possible.
Create a personalized profile in seconds with avatar selection, account setup, and onboarding flows designed to boost user activation and improve first-day retention rates.
An Instagram-style short video feed with smooth scrolling, engagement actions, content discovery, and AI-powered recommendations that keep users watching longer.
Real-time notifications for follows, likes, comments, gifts, and live streams, ensuring users stay engaged and return to the platform multiple times daily.
Private messaging with instant delivery, online presence indicators, media sharing, and conversation management built for seamless social interaction.
Creator-focused profile pages showcasing content, follower growth, engagement metrics, and social activity while helping users build their audience.
Real-time one-to-one chat with media sharing, message status tracking, and secure communication features that increase user engagement and retention.
A cohesive visual language designed for Dapke’s social, live, and creator-driven experience.
The stack reflects the needs of a media-heavy, real-time product: one cross-platform mobile codebase, event-driven communication, dedicated live video delivery, object storage and CDN distribution, fast-changing state in Redis, relational data and a separate feed-ranking layer.

See how the feed, live streaming, and gifting experience come together across Dapke’s mobile screens.
The admin side gives the operating team controls for users, creators, gifts, moderation, PK configuration, notifications and analytics so routine platform management does not depend on code changes for every action.

A product similar to Dapke cannot be priced accurately from the number of screens alone. Cost depends on the depth of the social graph, live-streaming model, PK and gift mechanics, calling requirements, feed ranking, moderation, admin controls, payment flows, platforms and third-party infrastructure.
Feed types, creator tools, messaging, calling, live streaming, battles and monetization change the engineering scope.
Live interaction types, concurrent session requirements and video delivery affect backend planning.
Moderation, reporting, admin workflows, analytics and transaction management add platform-side work.
Dapke was built and delivered and is currently awaiting the client’s public launch. Because public usage data is not yet available, this case study focuses on the delivered product scope and engineering outcome rather than presenting invented download, retention, revenue or user-scale metrics.
Feed, stories, live streaming, PK battles, gifting, chat, calling, ranking and administration were brought together in one product architecture.
iOS and Android share a Flutter-based product foundation.
Live events, chat, gifts and battle state are handled distinctly from standard application requests.
Media storage, CDN delivery and application services are separated so parts of the platform can be adjusted as usage changes.
These questions cover the product model, technology, live streaming, gifting, cross-platform development, feed ranking, administration and how Primocys approaches similar social or real-time application projects.
