Underpass is back (though it never left)

At long last, Underpass version 1.2.0 is now available in the Mac App Store and iOS App Store. Underpass for Mac was last updated in January 2019, and Underpass for iOS in December 2018. If you're not familiar, Underpass is a peer-to-peer file transfer and chat app with end-to-end encryption for complete privacy and security. Underpass is unlike any other chat app because it doesn't use a third-party service. The app is both a server and a client, so any two instances of the app running on a Mac or iOS device can make a direct network connection to each other, either on the internet or on a LAN, including ad hoc peer-to-peer wifi networks! You can use Underpass to exchange files and text between your own Apple devices or with another Underpass user.
