Arc

Stay on top of time, weather, markets, notes, and focus with a collection of desktop widgets.

Cross-platform desktop app for Windows, macOS, and Linux, built with Tauri 2, React, and TypeScript.

Beta — Arc is pre-v1. Features work, but bugs and breaking changes are expected.

Features

• System tray host — show, hide, arrange, and lock widgets from the tray
• Built-in widgets — Clock, Calendar, Crypto, Weather, Notes, Pomodoro
• Workspace controls — keep-on-top, auto-arrange (left/right columns), launch at startup, theme (dark / light / system)
• Locale options — English + Gregorian by default; optional Jalali (شمسی) calendar with Persian UI
• Settings window — configure workspace prefs and per-widget data in one place
