iClock

iClock is an ultra-lightweight, zero-dependency desktop floating countdown timer engineered for deep work and uninterrupted productivity on Windows.

Unlike bloated 100MB+ Electron-based timers, iClock is built with pure native Windows C# and GDI+ rendering. The single executable file is only 126 KB and uses under 15 MB of RAM, delivering 0.0% CPU overhead with 0 heap allocations per second during countdown.

Key Features:

• Transparent & Full Click-Through: Clean countdown numbers float naturally on your desktop. Using the native Windows WS_EX_TRANSPARENT style, mouse clicks pass straight through to underlying IDEs, games, or documents without stealing focus.
• Ultra-Lightweight (126 KB): Standalone single-file executable. No installation, no heavy runtimes, no dependencies, no registry junk.
• Global Hotkey Control: Toggle start/pause seamlessly with Ctrl + Alt + Space without leaving your current workspace.
• TopMost Confirmation Alert: When the countdown finishes, the overlay hides cleanly, displaying a persistent top-most dialog with chime alerts requiring acknowledgment.
• 100% Offline & Private: Zero network calls, zero tracking, and zero telemetry. All settings and history logs (clean daily TSV format) are stored locally in %APPDATA%\iClock.
• Easy Package Manager Installation: Supports both Windows Package Manager (winget install FrancoDeyvison.iClock) and Scoop (scoop install ...).
• Bilingual Interface: Easily switch between English and Simplified Chinese.
