Aurelis
Music collaboration shaped around rehearsal
Product mode
Local-first
Primary context
Rehearsal
Platform
Mobile
Overview
The product frame
Aurelis brings songs, setlists, organization libraries, and instrument-aware music tools into one mobile workspace. Guest work stays local; signed-in work synchronizes through Supabase without making connectivity a prerequisite for creating.
The Challenge
Musicians need to move between repertoire, service plans, and key changes while staying focused on the room—not on software administration.
Keeping guest work useful without an account
Representing musical keys and transposition as pure domain logic
Synchronizing local changes without losing pending work
Fitting setlist and song controls into a mobile rehearsal context
Architecture
A rehearsal-first experience with local-first editing, focused song views, quick transposition, and shared organization programs.
Pure music engine separated from React
Local-first guest persistence
Authenticated synchronization with Supabase and PostgreSQL RLS
File-based mobile navigation
Generated database type contract
