Onething

A focused productivity app built to help me finish what I start.

Why OneThing?

I struggled with:

• Starting multiple projects but not finishing them
• Context switching between tools (Productivity and TODO apps)
• Losing track of progress over time

OneThing exists to solve a single problem:
👉 focus on one project at a time and make visible progress every day.

This is a personal tool first, built to match my workflow. It also serves as a learning project to enhance my software engineering skills.

Core Features

• Native Desktop Experience: Advanced window management with a custom splash screen.
• Project-based TODO list
• Deadlines per project
• Project ideas + tool notes
• Daily progress logging
• Optional daily reminder notification
• Simple progress visibility over time
• Customizable Themes: Choose from Light, Dark, Baroque Blue, Forest, Celestial Night, Earthy, and Charcoal.
• Dynamic Design: High-contrast, focused visual system.

No cloud. No accounts. No distractions.

Tech Stack

• Frontend: SvelteKit + Tailwind CSS
• Desktop wrapper: Tauri v2 (Rust)
• Language: TypeScript / Svelte / Rust
• Storage: Local file storage (Tauri Store API) & localStorage
• System Integration: Native desktop notifications

The app is intentionally built as a web-first application so it can evolve into a desktop app without a rewrite.
