Joining the beta

• iOS needs Apple's free TestFlight app. Open the invite link above on your iPhone or iPad, tap Install, and TestFlight keeps you on the latest build. Beta builds expire after 90 days; a newer one always replaces them.
• Android: join the testing programme through the Play link above, then install Synapse from the Play Store as usual. You can leave the beta at any time from the same page.

Beta builds are pre-release: expect the occasional rough edge, and please report anything that breaks.

The workspace lives on your device and works offline. When you use more than one device, they sync directly or through a server you host, as described in Syncing your devices.

Building from source instead? See Install and configure, and the desktop and mobile build guides.
