An Akiflow-inspired, local-first time-blocking planner built for ADHD brains.

Plan your day by dragging tasks into your calendar — no backend, no account required. Your data lives on your device.

• Local-first — data stored in local SQLite, never sent to a server; works fully offline
• Device sync — opt-in, end-to-end encrypted sync across devices via Evolu relay
• Drag & drop — drag tasks from inbox onto the calendar, resize blocks, drag back to unschedule
• Time-blocking calendar — week view and 2-day (today/tomorrow) dashboard view
• Inbox — capture tasks and quick notes (// prefix) in under 3 seconds
• Transition buffers — configurable breathing room between blocks
• Keyboard navigation — operate the full UI without a mouse
• Dark mode — warm paper-industrial aesthetic, light and dark
• Notifications — optional reminders before blocks end
• Priority system — color-coded none / low / medium / high

Dashboard view — today and tomorrow side by side

Week view — full 7-day calendar

No backend is required. Everything runs in the browser.

• Node.js 18+
• npm, yarn, or pnpm

git clone https://github.com/nktrjsk/flowblock.git
cd flowblock
npm install
npm run dev

Open https://localhost:5173.

The app requires a secure context (HTTPS or localhost). Serving over plain HTTP will break local storage and calendar sync features.

npm run build

Output goes to dist/. Deploy to any static host — GitHub Pages, Netlify, Vercel, etc.

npm run build
# push dist/ to gh-pages branch, or use a GitHub Actions workflow

FlowBlock uses Evolu for optional device sync. Sync is:

• End-to-end encrypted — the relay server sees only ciphertext
• CRDT-based — conflicts resolve automatically, no merge dialogs
• Opt-in — if you never set up sync, your data never leaves your device

To sync, open Settings → Identity and copy your owner key to the second device.

Note: This is an experimental, unreliable feature. Both ICS and CalDAV require a CORS proxy to work in the browser — direct fetches are blocked by browser security policy. Set up a proxy in Settings → Advanced.

You can overlay read-only events from external calendars:

1. Open Settings → Calendars
2. Add an ICS feed URL or a CalDAV server
3. Events appear in the calendar as dashed blocks beneath your time blocks

• CalDAV write — sync time blocks back to CalDAV
• Projects — group tasks by project with rotational weight
• Energy capacity bar — plan by energy, not just time
• Routines — recurring time block templates
• Review mode — weekly retrospective view
• Smart suggestions — AI-assisted scheduling

WTFPL — do what the fuck you want.
