Tech entrepreneur Jack Dorsey has released a pair of apps recently, continuing his focus on decentralized communication. Tech expert Omar Gallaga says Dorsey’s new messaging app doesn’t require internet access to connect. 

Highlights from this segment:

– Jack Dorsey founded Twitter, Bluesky and Square – all apps and companies that have made a major impact on the internet. 

BitChat is Dorsey’s new messaging app that uses Bluetooth and mesh networking, much like Tile and Apple AirTags do to help people find lost objects.

Sun Day is another Dorsey app, this one focused on helping users track their sun exposure. It’s currently in beta.
