Reddit Sync is one of the numerous apps Android users can grab in the Play Store to keep up with the site from a mobile device. With the release of version 10, the UI has been hit with a dose of Material Design, just like the Android subreddit before it. The menu button's been detached from the edge of the screen, the side menu now covers up the action bar, and the status bar has turned a tinted shade of blue.
If you use the device security suite Cerberus, the app is getting one of its biggest updates ever in a couple of weeks, but you can grab it on the beta channel right now if you're not inclined to wait / want to be a guinea pig. Version 3.0 overhauls the design of the app to meet Google's material guidelines (as interpreted by Cerberus, of course), but there are a bunch of features packed in there, too.
The Office mobile app just got an update, and for once it's bringing something you might care about. The latest update adds the Dropbox integration that was announced early this month. You can now open, edit, and save documents in Dropbox using the Office app.
A pair of Amazon apps have popped up in the Play Store, but they're both for pieces of hardware you can't get yet. The Amazon Echo app is the companion to Amazon's bizarre connected speaker, and the Fire TV remote app adds functionality to the Fire TV Stick. I would wager the second will get more downloads.
While it's been available on iOS for some time, United updated its Android app today in order to add support for a rather cool feature: on-device entertainment. Instead of having to deal with that atrocious LCD on the headrest, now you can watch your in-flight movies and TV on your own phone or tablet.
This is likely both a blessing and a curse. Who knows what the stream quality is like (anyone with an iPad who's used it want to chime in?), not to mention the reliability.
You may not use WhatsApp to send messages, but it's still the most popular messaging platform in the world. As such, it's a big deal when the switch gets flipped and all those messages are suddenly encrypted. That's what the company is doing now thanks to the just-announced integration of the TextSecure protocol from Open Whisper Systems.
