Do you wish there was a more secure option for sending text messages and even making calls from your phone? Wouldn’t it be great if that option utilized end-to-end encryption to ensure that your communications were entirely protected? Well, that option exists in the form of Signal.

Signal is an open source app that supports text and calls. It’s available for Android and iOS, and it has desktop clients available across platforms. If you’re wondering exactly how trustworthy Signal is, it was endorsed by Edward Snowden and the EFF. It’s pretty safe to say that it’s a good option.
