TechKnow With Tantra: Bridgefy – Offline Messaging

This app allows you to communicate with others (with the App) even without internet connection, via via Bluetooth up to a 100 meter distance. Even if you’re not within 100 mts of each other, you could still communicate, via other Bridgefy users in between, where the message moves through the intermediate users to reach the final recipient. The intermediate users cannot read the message. It’s ideal for festivals, sports stadiums, rural communities, natural disasters, travel, etc. 

In case of calamities, you can use the broadcast mode, sending messages to all within the range at the same time, even if they are not in your contacts list.
