Signal Private Messenger is actually a messaging app much like Hangouts, WhatsApp, Facebook Messenger, and others. The difference is that this one features end-to-end encryption and it’s been a favorite of many people who value security. It also works on a phone number system and if your contact doesn’t have the app then it simply sends a text message. We really liked how seamless that feature is. It’s simple to use, looks great with Material Design, and it is entirely free to use with no in-app purchases. It’s also open source, supports group chats, and it’ll even make phone calls.
Feedly takes the RSS feed into the modern age, and it's the easiest way to stay on top of all your favorites sources of news. You can view everything all at once if you want, but Feedly also lets you categorize your sources for focused reading or use its Today tab, which shows you the top stories from each category. Additionally, you can make Feedly look as simple as you wish, with minimalist text-only layouts. It's a great way to keep informed with the days' headlines and it offers useful integrations with other services as well. New Droid Apps
Google Opinion Rewards is appropriately named. Google sends you surveys that ask you about places you've visited recently and you get Google Play Store credit for your participation. Polls don't come in very often, but you can increase your chances of receiving more, by enabling your location and answering surveys quickly and honestly when they do arrive. It's not going to earn you a ton of store credit, but it's enough to purchase an app or an album every so often. To add some perspective, one of our editors has earned about $64 since installing the app in late 2013. Droid App
