Before releasing each software update, we briefly test it in beta. If you want to get a bugfix or new feature a little bit earlier, you can use this beta version; the downside is you're more likely to run into new bugs.
To use the beta version:
On the desktop app, select Beta Channel from the Receive Beta Channel Updates drop-down in Settings > Desktop App:
After selecting this option, RemNote will check for updates on the newly selected channel, and if there's a newer version on that channel, you'll be prompted to reload the app to install the beta version as soon as the update finishes downloading.
On the Android app, you can select the beta channel from within the Play Store. There is no publicly available beta version for the iOS app at this time.
