The problem

Walking apps often turn a personal habit into a surveillance product. Rainbow Wander is designed to make exploration feel playful and rewarding without asking people to trade away their precise movements.

The product decision

Each walk paints the world: blocks bloom, colors can be collected, and moments can become photo memories. A companion, collection cabinet, and progress surfaces turn a map into something closer to a small world than a fitness dashboard.

What I own

I lead the product concept, visual language, interaction design, privacy posture, and Android implementation. The experience is built in Jetpack Compose with Mapbox handling the map layer and DataStore supporting local preferences and progress.

Privacy is part of the interaction

Mapbox telemetry is disabled. Location and usage data stay on-device. Paint Together is deliberately opt-in and shares only an anonymous, coarse projection of a painted cell, color, and tier—never precise location or timestamps.

Current state

The Android build includes the living map, blooms, color collection, memories, a companion, profile and stats surfaces, settings, and store-ready visual assets. It is presented as in progress while release preparation continues.
