10K Sprint Day 4: In-App Direct Messaging System

July 11, 2026

Welcome to Day 4 of the 10K Sprint! Today, we added the ultimate utility for maintaining friend connections: Direct Messaging.

The Purpose

A social network isn't complete without a private channel to talk. If users have to leave Alavita to discuss a shared workout or arrange a gym meetup on WhatsApp or iMessage, we lose engagement.

By building native, real-time messaging directly into Alavita, we keep the conversation inside the app and reinforce the social bonds of our fitness network.

What We Shipped

  1. Real-time DM Architecture: Built direct messaging utilizing Supabase Realtime streams for instantaneous message delivery.
  2. iMessage-Style Chat UI: Designed a premium chat interface featuring distinct bubble layouts, read receipt badges, and message time separation.
  3. Inbox Management: Added an inbox screen accessible directly from the social feed, showing active conversations, last message previews, and unread counts.
  4. Direct Profile Action: Added a "Message" button directly onto user profile cards so you can start a chat with any friend in one tap.

The Goal

Direct messages make Alavita a utility for communication. When users chat about fitness goals, send positive vibes, or coordinate workouts, they form a sticky habit that dramatically boosts customer retention.

We are flying through this sprint. Catch you tomorrow for Day 5!
