Building now · MVP targeting spring 2026

Your personal
soundtrack
for reality.

A music app that knows where you are, what time it is, and what you're doing — then plays the perfect song. No scrolling. No choosing. Just living.

The Concept

Every place has
its own theme.

In games, walking into a new area changes the music. Overworld does that for real life — matching soundtracks to the world around you.

🏖️ BeachAfternoonWalking

Sun on your face, sand underfoot, waves in the distance. The music just fits.

Neon signs flicker on. The city hums around you. Main character energy.

How It Works

Three dimensions
of context.

Overworld connects to Apple Music or Spotify — your playlists, your albums, your library. It reads where you are, what time it is, and what you're doing — then plays the perfect match.

01📍

Location

Create “grids” — zones classified by type. Beach, park, city, residential. Not specific addresses — types that work anywhere in the world.

02

Time

Morning energy is different from evening calm. Overworld adapts your soundtrack as the day progresses.

03🚶

Activity

Walking gets exploration vibes. Sitting gets focus beats. Driving gets road trip energy. Motion sensors handle it.

Manual Mode

Quick scene switching. Zero battery drain. The default for everyone.

Automatic Mode

Opt-in hands-free. Motion-triggered, battery-optimized. Music flows as you move.

Free to use. Seriously.
Create zones, paint your map, play your music — all free, forever.
Premium unlocks community sharing and automatic mode. $4.99/month.

The Grid System

Your city, your
sonic zones.

Draw zones on a map. Classify them by type. Assign soundtracks. Walk through them and the music changes.

The Differentiator

Shared sonic
landscapes.

Create grids for your city. Share them globally. When someone visits, they experience the world through your ears.

Why I'm Building This

I want to walk to the beach and have it just know to play Maplestory Aquarium. I want city walks to feel like moving through a game world.

I've wanted this for years. The Sony XM6's auto-scene feature came close but felt too limited. I can build the thing — I just need people who care about music and places to help make it something special.
