Silent Phone

Silent Phone is one of several encrypted communication services offered by Silent Circle, the developer behind the Blackphone security-focused smartphone range.

Silent Phone is a subscription-based service which harnesses end-to-end encryption with the keys held by the subscriber rather than the company, and so no government eyes can snoop on your calls. The service also offers secure conference calls, messaging and file transfers.

ChatSecure

ChatSecure, available for Android and iOS, is a highly-rated open-source encrypted messaging option which supports OTR encryption over XMPP. While this option is best for Android users -- as Apple does not permit an 'always on' setting on iOS for the app -- the app is also flexible and can be used with other XMPP-based software.

BlackBerry Messenger

While the numbers of BlackBerry users have dwindled in recent years with the rise of iOS and Android, BlackBerry Messenger (BBM), which can also be used on other operating systems. Messages sent through the service are encrypted and pass through both a firewall and BlackBerry servers before being passed on. Decryption keys on the recipient's device are the only way messages can be unpacked.

Wickr

Available for Android and iOS, Wickr is an app for secure messaging. The strength in the app lies in the self-destruct feature for messages, allowing you to set a time and date for your messages to expire and become automatically deleted. This can help shield your communication from third parties, and every message sent is also passed via end-to-end encryption.

Apple iMessage

It isn't common for default mobile apps to also offer decent encryption and protection, but Apple's iMessage does. The app supports end-to-end encryption -- which means that even the company itself cannot give law enforcement access to conversations unless message backups are stored in an unencrypted fashion to the iCloud.

Facebook Messenger

In a move praised by many, the social media giant recently announced plans to roll out end-to-end encryption for conversations taking place on Facebook. While the security enhancement isn't yet worldwide, if you already have the option, you need to opt-in through the settings tab to keep your conversations safe.
