OneTrack is a lightweight desktop app for Windows that keeps your timer in the system tray, adds screenshots and activity levels, and sends every hour to your timesheets and invoices.

A 64-bit installer for Windows 10 or later. Show the app in the taskbar, the system tray, or both, and keep it on top in compact mode if you like.
Start the timer on a client, project and task. The app counts time in ten-minute slices, gives each an activity level, and takes screenshots at random moments in the capture window you choose.
It shares one clock with the web app, so a timer started in your browser shows here too, and a pause or stop reaches the other within seconds.

The timer and its controls live in the system tray, so you can close the window and keep tracking. Set the app to launch when you log in, starting hidden.
Choose whether to be notified when a screenshot is taken or the timer starts or stops, and when to be asked about idle time.

Each slice is saved the moment it ends. Offline, your time and screenshots wait on your computer and upload when you're back online; captures more than 72 hours old are dropped unsent.
Quit the app and it uploads what's left first, showing you what it's still sending.
