A self-hosted personal productivity app — tasks, habits, events and projects — running on a Raspberry Pi on your own network. No cloud account, no third party, and the database is a file you can pick up and take with you.

It is also the app the pantry voice assistant drives, so a task added out loud in the kitchen shows up in the browser a couple of seconds later.

Most task apps have one "priority" field, which quietly conflates two different questions: how much does this matter and how soon. LifeOS keeps them apart.

importance = task priority + domain priority          20–80
urgency    = urgency field + time pressure            10–120
score      = importance × urgency / 100

Multiplied rather than added, so something both important and urgent pulls clearly ahead of something that is a bit of each. Recalculated daily, so an approaching deadline actually moves a task up the list instead of leaving it frozen at the score it had when written.

Time pressure comes from a deadline if there is one, and from neglect if there is not:

A real deadline still beats a vague intention — but a task you have ignored for three months is more pressing than one due in three months, and without the second ladder undated work could never rise however long it rotted.

Today — habits, events and tasks for today, an effort meter for the day, and a strip for plans whose day has passed asking what you want to do about each one.

Week — seven days. A task appears once: on the day you planned it, or on its due date if you have not planned it, drawn dashed so a deadline looks different from a commitment. Finished work stays put, greyed.

Plan — triage what needs attention, drag unscheduled tasks onto a day/week/month calendar, or let auto-suggest fill a week within a daily effort budget. Plus an Eisenhower matrix over the two scoring axes.

Tasks — the full table: search, multi-select filters, column control, saved presets.

Projects group tasks with AP-weighted progress. Habits recur on a cadence or a weekly target, with streaks and a 30-day history. Domains are life areas whose priority feeds every task's importance.

Tasks promote themselves: give one a name and it waits in Needs Details; fill in priority, urgency, domain and an effort estimate and it becomes Backlog, or Planned once it has a date.

npm install
npm run dev            # http://localhost:3000

The database is created on first run. Add a profile before using the app:

node scripts/user.cjs add dk "DK"

npm run build && npm start   # production
npm test                     # vitest
npm run lint

Runs under systemd and is published to the tailnet with Tailscale Serve, so it is reachable from a phone or laptop without opening anything to the internet. A timer snapshots the database nightly, skipping unchanged nights and verifying what it wrote.

Snapshots share the SD card with the database, so they do not protect against the card failing — Settings → Your data downloads everything as a single JSON file, and restores one. The app reminds you monthly.

Next.js 16 (App Router), React 19, Tailwind 4, TypeScript. SQLite through node-sqlite3-wasm — the native addon segfaults on Debian 13 aarch64. Dates via date-fns, charts via Recharts.

Installable as a PWA and works at phone width.
