Notes on downloads

FAQ

Can I watch with friends who use Syncplay on PC?

Yes. Synkplay implements the same protocol, connects to the same servers, and supports the same features.

Android says "App not installed" when updating?

Uninstall the previous version first, then install the new APK.

I don't have access to the iOS App Store.

You can sideload via AltStore (non-jailbroken) or install the .ipa file directly (jailbroken).
