A fast native shell around the full ThynkBooks workspace — system tray, native notifications, deep links, and automatic updates. Same product, same data as the web.

Installers
The Windows app is ready to download below. macOS and Linux builds are rolling out — until then your onboarding contact can share a build, or you can use ThynkBooks in any modern browser today.
macOS 12 or later · universal .dmg
Ubuntu 20.04+ · .deb and AppImage
.msi. The app isn’t yet code-signed with a commercial certificate, so Windows SmartScreen may show “Windows protected your PC” — click More info → Run anyway. Once installed, it opens the full ThynkBooks workspace and stays current with every web release automatically.Why the desktop app
The desktop loads the same workspace as the web app, so every product update is live the moment we ship it — no reinstalls.
Approval requests, overdue invoices and anomaly alerts arrive as system notifications, even when the window is closed to tray.
thynkbooks-desktop:// links open straight into the right record, and the tray keeps ThynkBooks one click away all day.
Point the app at your own ThynkBooks server from the built-in server settings — nothing is hard-wired to our cloud.
