Signal got an influx of richly deserved new users, and Android users bemoaned the fact that they can’t switch to Apple’s iMessage.

According to its website, the app supports 14 external messaging platforms as well as its own Beeper network.

Beeper has two ways of enabling Android, Windows and Linux users to use iMessage: we send each user a Jailbroken iPhone with the Beeper app installed which bridges to iMessage, or if they have a Mac that is always connected to the internet, they can install the Beeper Mac app which acts as a bridge.

Many of the services that it aggregates use some level of end-to-end encryption, and Beeper needs to be able to guarantee users that they can expect the same level of security that they would have when using any of the standalone services.

Beeper didn’t immediately respond to Gizmodo’s request for comment on its encryption policy, and we’ll update this post when we receive a reply.

Here’s the list of messaging services that are compatible with Beeper:.
