SnapConnect: Product Requirements Document (PRD)

1. Introduction

SnapConnect is a mobile social media application designed for users to share moments with friends through images and videos in real-time. The core concept revolves around ephemeral content, where shared media is automatically deleted after 24 hours, fostering spontaneous and authentic communication. The app will also feature robust social functionalities including a friend system, commenting, stories, and group messaging.

2. Project Goals and Objectives

  • Primary Goal: To create an engaging and intuitive Android application that allows users to connect and share their lives with friends through ephemeral media.
  • Objectives:
    • Develop a secure and scalable user authentication system.
    • Implement real-time features for content sharing and messaging.
    • Ensure a seamless and responsive user experience.
    • Build a reliable system for managing friendships and social interactions.
    • Leverage Supabase for all backend services, including authentication, database, storage, and serverless functions.

3. Target Audience

  • Primary: Teenagers and young adults (ages 16-25) who are proficient with social media and value instant, visual, and private communication with their close friends.
  • Secondary: A broader audience looking for a fun and simple way to share day-to-day moments with family and a select group of friends without the pressure of a permanent digital footprint.

4. Core Features

4.1. User Authentication

  • Sign Up: Users can create a new account using an email and password.
  • Log In: Registered users can log in to their accounts.
  • Log Out: Users can securely log out of their accounts.
  • User Sessions: User sessions will be managed securely to keep them logged in across app launches.

4.2. Friends Management

  • Add Friends: Users can search for other users by their unique username and send friend requests.
  • Friend Requests: Users will receive notifications for new friend requests and can accept or decline them.
  • Friends List: Users can view a list of their current friends.
  • Delete Friends: Users can remove other users from their friends list.

4.3. Real-time Image and Video Sharing

  • Camera Integration: Users can access the device camera from within the app to capture photos and record videos.
  • Content Posting: Users can post captured images and videos.
  • Audience Selection: Before posting, users can choose to share with specific friends, add to their story, or send to a group chat.

4.4. Ephemeral Content (Stories)

  • 24-Hour Lifetime: Images and videos posted to a user's "Story" will be visible to their friends for 24 hours.
  • Automatic Deletion: After 24 hours, the content will be automatically and permanently deleted from the backend. This will be handled by a Supabase Edge Function or a database trigger.
  • Story Viewing: Users can tap on a friend's profile/name to view their current story.

4.5. Comments

  • Add Comments: Users can write and post text-based comments on the images and videos within their friends' stories.
  • View Comments: Comments on a story post will be visible to the post's author and other friends who can view the story.

4.6. Group Messaging

  • Group Creation: Users can create group chats and add multiple friends to the conversation.
  • Text Messaging: Members of a group can send and receive text messages in real-time.
  • Media in Chat: Users can share images and videos (snaps) directly within the group chat.

5. Technical Stack

  • Frontend: Android (Kotlin)
    • UI: Jetpack Compose for building a modern, declarative UI.
    • Architecture: MVVM (Model-View-ViewModel)
  • Backend: Supabase
    • Authentication: Supabase Auth for user sign-up and log-in.
    • Database: Supabase (Postgres) for storing user data, friend relationships, comments, and message history.
    • Storage: Supabase Storage for hosting user-uploaded images and videos.
    • Realtime: Supabase Realtime for instant messaging and live updates.
    • Edge Functions: Serverless functions for custom logic, such as the automatic deletion of posts after 24 hours.

6. Success Metrics

  • User Engagement: Daily Active Users (DAU) and Monthly Active Users (MAU).
  • Content Creation: Number of images and videos posted per day.
  • Social Interaction: Number of friend requests sent, comments made, and group messages exchanged.
  • User Retention: Percentage of users returning to the app week-over-week and month-over-month.

7. Future Considerations (Roadmap V2)

  • "Memories" Feature: An opt-in feature to save favorite posts before they are deleted.
