Taskline ⏳

Set a deadline. Get reminded on time. Even if the app is closed.

A small, focused task & deadline reminder — one thing, done well. Create a task, set a deadline, and Taskline fires a local notification when the time comes, even if the window is closed.

The idea

Bills, appointments, and one-off chores — "pay the electric bill by today" — slip through the cracks. The heavyweight to-do apps want accounts, cloud sync, and a monthly fee to do it. I just wanted a thing that reminds me on time and then gets out of the way.

So Taskline does exactly that: local-only, no accounts, no telemetry, no network. It lives in the tray, fires a Windows toast when a deadline approaches, and that's it. Open it, set it, forget it.

Features

Tasks

• Title, description, due date and time.
• Two tabs — Upcoming / Complete — with swipe-to-complete and swipe-to-delete.
• Recurring tasks — daily / weekly / monthly (monthly clamps to month-end so Jan 31 → Feb 28).
• A calendar view of everything on your plate.

Reminders

• Smart lead times — six configurable buckets (1 hour out → more than a year out), each with its own frequency. A deadline a month away nudges you differently than one an hour away.
• Windows toasts that fire even when the app window is closed.
• All scheduling is derived automatically — change a task or a setting and the whole reminder schedule re-computes.

Around the app

• System tray — closing the window minimizes to tray so notifications keep working; real quit is in the tray menu.
• Launch at Windows startup (optional).
• Single instance — a second launch just surfaces the running window.
• Customizable 12/24-hour clock and date format.
• Terminal-brutalist theme — monospace type, CRT-phosphor green palette, hard-edged boxes.

How it works

A single Flutter codebase; Windows desktop is the shipped target.

• Local-only storage — SQLite for tasks, shared_preferences for settings. Nothing leaves your machine.
• State via Riverpod — mutations are optimistic (the list updates instantly, then persists), and loading the task list re-derives the full notification schedule.
• DateTimes are UTC at rest, local for display — recurrence and reminder math stay pure and unit-tested.
• Slotted notification IDs — each task owns a 100-ID block, so cancelling and rescheduling a task never collides with another's reminders.

Install (Windows)

1. Download taskline.msix and taskline.cer from the Releases page.

2. Trust the signing certificate (one-time). The MSIX is self-signed. In PowerShell as Administrator:

   Import-Certificate -FilePath taskline.cer -CertStoreLocation Cert:\LocalMachine\TrustedPeople

   Or via the GUI: right-click taskline.cer → Install Certificate → Local Machine → Place all certificates in the following store → Browse → Trusted People → Finish.

3. Install. Double-click taskline.msix → Install. Taskline appears in the Start Menu.

4. First run. Open it from the Start Menu. Optional: Settings → General → Launch at startup.

To uninstall: Settings → Apps → Installed apps → Taskline → Uninstall.

Develop

Prerequisites: Flutter SDK (stable), Visual Studio 2022 with the Desktop development with C++ workload and C++ ATL for v143 build tools, Git, PowerShell. Run flutter doctor and expect green checks for Flutter, Windows, and Visual Studio.

git clone https://github.com/POSTTTT/Taskline.git
cd Taskline/taskline
flutter pub get
flutter run -d windows

Build

# Unsigned exe → taskline/build/windows/x64/runner/Release/taskline.exe
flutter build windows --release

# Signed MSIX (from repo root)
powershell -ExecutionPolicy Bypass -File scripts/create-signing-cert.ps1   # one-time cert
powershell -ExecutionPolicy Bypass -File scripts/build-release.ps1         # build + sign

The signed taskline.msix lands in taskline/build/windows/x64/runner/Release/; the matching public cert is scripts/taskline.cer (committed).

Roadmap

See PLAN.md. Windows v1 has shipped (Phases 0–5). Next up: mobile port (Android, iOS), then cloud sync.
