Ensō's Todo app: a launch checklist with subtasks nested three levels deep and the lists rail on the left

Half a minute of Ensō

Today's agenda, a task added from the keyboard, the calendar, a page of notes, and two apps side by side. All of it works offline.

Ensō's Agenda: today's events, due tasks, reading, and the daily note in one view

For students and busy generalists

Classes, deadlines, notes, and reading — one app, works offline.

  • Every due date lands on the calendar next to your events, and the Agenda shows the day in one view.
  • Notes with a real block editor and [[page links]]; save articles to read later, with the full page kept offline.
  • Works on the bus, in the lecture hall, on the plane. Free for 14 days, no card.

Ensō's Calendar: a month view with colour-coded events and task chips on the days they are due
For knowledge workers

Projects with real work-breakdown, notes like Notion, a calendar that knows your tasks.

  • A keyboard-first outline with milestones, dependencies, and roll-ups — and a Gantt view beside it.
  • Split view: the plan next to its notes, the agenda next to your email.
  • Ctrl+Space opens a command palette that jumps anywhere or captures a thought without the mouse.

For the privacy-minded

Your data is a SQLite file on your device. Sync is optional, Vaults are built in, export is one click.

  • Lock any list, calendar, project, or notes folder behind a password — end-to-end encrypted with Argon2id and XChaCha20-Poly1305.
  • The server stores ciphertext it cannot read; the plaintext never leaves your devices.
  • Export everything as a zip whenever you like, and delete your account yourself.

Eight apps, one database

A tabbed suite of focused modules that share one database, one search, and one sync engine.

Search, palette, split view

One full-text search across everything. Ctrl+Space for the command palette. Two modules side by side when you need them.

Make it yours

Three themes, each with a light and a dark variant. Remembered per device, so the phone in the sun and the desk monitor can disagree. Shown here in your device's current appearance.

Offline-first, for real

Most "offline modes" are caches. Ensō puts a real database on every device you own.

  1. A real local database

    Native SQLite on desktop and mobile; SQLite compiled to WebAssembly in your browser. Everything works with no connection at all.

  2. One merge engine

    The same conflict-resolution engine ships in every client. Edits made offline on two devices converge the same way, every time.

  3. Quiet, continuous sync

    A background loop reconciles your devices every 15 seconds whenever you're online. No sync button, no "last writer loses".

  • On the App Store, Google Play, and the Microsoft Store
  • Your data in an open SQLite file, on your device
  • One-click export of everything, any time
  • No card for the trial, cancel in one click

Questions people ask

Does it work offline?

Yes — on every platform, not just the desktop app. Each device keeps a real SQLite database (in the browser it's SQLite compiled to WebAssembly), so everything is readable and editable with no connection. Changes sync when you're back online.

Is my data encrypted?

Everything travels over TLS. On top of that, Vaults let you lock specific lists, calendars, projects, or notes folders behind a password with end-to-end encryption (Argon2id key derivation, XChaCha20-Poly1305) — the server stores only ciphertext it cannot read.

What happens after the trial?

Every account starts with a 14-day free trial, no card needed. After it, your data stays on your devices and sync pauses until you subscribe. See pricing for the plans.
