Communication and messaging
Facebook now offers its messenger service as a standalone app, enabling you to chat with your Facebook friends and anyone in your contacts with the app installed, without having to be signed into Facebook. We recommend this app for the sheer volume of messaging that happens via Facebook, though it’s a little frustrating that the Facebook app itself no longer includes messaging functionality.
The de facto VOIP service that is owned by Microsoft, Skype is used by more than 250 million users worldwide. Offering free international voice and video calls is a tough deal to pass up.
It’s also a standard texting and messaging app, but Hangouts was merged with Google Voice. It now gives you the ability to make video and voice calls, giving you a nifty all-in-one solution.
WhatsApp is a great choice for anyone that doesn’t have unlimited texting and spends a lot of time connected to Wi-Fi, letting you send and receive messages, pictures, audio notes, and video messages.
Slack is the premier messaging app for teams and companies, allowing for clear communication throughout every level of your organization. Slack instantly syncs across all devices and is compatible with dozens of other apps and services (like Dropbox) to make your job simpler and easier.
Wickr Me is a free end-to-end messenger app loaded with features to secure all of your messages and in-app media. You can adjust the Configurable Timer to set a specific expiration date on all of your content as well.
