1. Same app, a native shell on Windows
The Windows desktop app is a native shell around app.pileform.com, not a separate product: everything you can do in the browser, you can do in the desktop app. What it adds is a few native conveniences, a system tray icon, native OS notifications, unread badges, drag-and-drop of files straight onto the window, and silent auto-update in the background. The desktop app is localised in English and Greek.
2. Mac and Linux: the browser app
There's no separate Mac or Linux build; on those platforms, the web app runs in any modern browser with the same features as the desktop app, upload, review, posting, payroll, and the compliance calendar all included. If you're switching machines or just prefer not to install anything, the browser is always a complete option, on any platform.
