Think about the last time you planned a trip.
📱 You opened your airline's app to check flights.
🗺️ Switched to Google Maps for directions.
💬 Used WhatsApp to coordinate with friends.
🌍 Maybe downloaded a translation app just for the week.
📸 And after the trip? You probably dug through Photos and a budgeting app to figure out what you spent.
That's five or six apps — all for one journey.
This is normal today. But it doesn't feel right, does it?
We live in a world where apps are still siloed products. App stores want you to search, install, and learn them one by one. But our lives don't fit into silos. We live in flows — trips, health check-ups, courses, projects — and those flows cut across dozens of apps.
This series is about a different way of thinking:
Mosaic
What is Mosaic?
At its core, Mosaic is a vision:
- Instead of monolithic apps, we think in tiles — small modular capabilities.
- A user's intent ("I'm visiting Tokyo") becomes the starting point.
- The right set of tiles assemble into a cohesive app, just for that journey.
- And as your journey changes, the app reshapes itself.
How Mosaic assembles the right capabilities for your specific journey
In the coming parts of this series, I'll unpack this vision step by step.
What This Series Will Cover
- Part 1 — The Problem with Apps Today
You're reading it! Why app stores and siloed apps don't fit the modern user journey. Introduce the Mosaic concept at a high level. - Part 2 — The Mosaic Concept: Adaptive Journeys
Deep dive on "tiles," adaptive layouts, self-updating flows. Tokyo trip example. - Part 3 — Under the Hood: Context Engine, Registry, Composer
Explain the building blocks and why this differs from MCP/agents. Discuss security, version locking, rollbacks. - Part 4 — Near Future & Beyond
Why PWAs are the natural first step. The long-term OS-level vision. Examples: travel, health, learning.
Why Start Here?
Before we can imagine a new model, we need to clearly see what's broken today:
- Too many apps. Every task means juggling 3–5 different tools.
- Too much friction. Search, install, learn, delete. Repeat.
- Too little adaptability. Apps don't evolve with your journey.
Mosaic is my attempt to rethink this from the ground up.
Homework for You
Before the next part, here's a simple exercise:
👉 Think of one thing you did this week that required 3 or more apps.
Write them down. How did it feel switching back and forth?
Hold onto that example — we'll revisit it in Part 2, when we imagine how Mosaic would handle it.
