IdeaQuantum Outliner

A personal project I designed, built and run every day, working with Claude Code as an AI pair programmer: a Mac app in Electron, React and SQLite, an iPhone app in Expo, and a sync server they share. It builds on Electron and SQLite work going back to 2022, and it holds my own task list, so reliability isn't optional.

The Outliner on a Mac: a sample household list on the left, and today's plan on the right, split into Morning, Afternoon and Evening.
Offline-first sync
Mac and iPhone edit the same outline. Automerge CRDTs and an ordered operation log let devices merge changes without conflicts or lost rows.
Multi-tenant server
A Node.js hub with per-account data isolation, hashed keys, Sign in with Apple, rate limiting and nightly backups, deployed behind Caddy on a VPS.
Safe data migration
Moved the source of truth from SQLite tables to a CRDT document in stages, with every save compared field by field before the switch.
Release engineering
Scripted builds, notarization and TestFlight delivery, CI on every pull request, and cryptographically signed over-the-air phone updates.
The Outliner on an iPhone: a sample day's plan, with one overdue row and a morning routine that is two of three ticked.

As of 30 October 2026. Screenshots show sample data.

What a data loss taught me

In September 2026 an operating system upgrade wiped the Mac holding the outline, and every scheduled backup was on that same drive. The data came back from a copy that happened to exist elsewhere.

I treated it as a design failure. Backups now run on a schedule to off-site storage, retention is automated, and a failed backup raises an alert instead of failing silently.
