QdoShare is a single executable file. No installer, no runtime dependencies, no background services, no auto-update daemons. Drop it on the desktop, double-click, and the timer is running. It uses a few megabytes of RAM, takes no measurable CPU, and closes the instant you tell it to. The lightest possible tool for the simplest possible job.
Get the Timer — FreeMost desktop timers are not just timers. They are installers, updaters, settings sync services, telemetry agents, and tray-icon managers bundled into a 200MB package that runs four background processes and adds three seconds to your boot time. They do everything except, sometimes, tell you the time.
QdoShare is the opposite. It is one file. It does one thing. It opens in under a second, runs in a few megabytes of memory, and exits the instant you close it. No installer, no first-run wizard, no "do you want to set QdoShare as your default timer?" dialog. You double-click. The timer is there. That's the entire experience.
This matters more than it sounds. A presenter's machine is already running PowerPoint, Zoom, browser tabs, and a dozen other things. The last thing it needs is a timer that competes for resources. QdoShare stays out of the way at every level — visually, behaviorally, and computationally.
When PowerPoint, Zoom, and screen-sharing are already maxing out your CPU, you don't need a timer adding load. QdoShare uses essentially zero resources — it's invisible to Task Manager.
On a shared conference-room PC, you can't install software. QdoShare runs from a USB stick or a network share — no installation, no admin rights, no trace left behind when you log out.
Two minutes before your talk, you realize you need a timer. With QdoShare on your desktop, double-click and it's running in under a second. No setup, no preferences to configure, no learning curve.
On a long flight or in a conference hall with no outlets, every CPU cycle drains your battery. QdoShare's tiny footprint means the timer keeps running without noticeably shortening your session.
Many companies block software installations. QdoShare runs as a standalone executable — no installer needed, no admin permissions, no IT ticket to file. Just run it.
Drop the executable on a USB stick. Plug it into any Windows machine — your laptop, a colleague's, a client's conference room — and your timer is right there. Same settings, same behavior, no setup.
Three architectural choices keep the executable tiny and the runtime quiet.
QdoShare ships as one .exe file. No setup wizard, no DLLs, no registry edits. The file is small enough to email, drop on a USB stick, or download in seconds.
When you close QdoShare, it's gone. No tray icon, no auto-update daemon, no "QdoShare Helper" still running in Task Manager. The process exits cleanly and completely.
Built directly on the Win32 API and a standard Python GUI toolkit — no Electron, no Chromium, no embedded browser. This keeps memory usage low and startup time near zero.
