Mood Messenger is one of the youngest apps on our list. It doesn’t have a million and a half features, but that’s one of the nice things about it. Mood Messenger keeps things simple while still offering the key features you’ll want. Mood Messenger users can also send messages to each other without using SMS. The app is completely free with no in-app purchases. Droid App
Last year, we wrote that one of the best features of QKSMS was its open-source nature, allowing for anyone who wishes to change aspects of the app to do so by diving into the openly-available source code. QKSMS remains open-source, but unlike last year, a new “Plus” tier has been added to the app that adds support for automatic night mode (as mentioned above), a full color slider for picking out literally endless colors, and additional upcoming features promised by the dev, including message backup, delayed sending and scheduled messages, auto-respond and auto-forward, and more. There’s no ads in QKSMS, and most people may find the free tier suitable for their liking, but if you want to upgrade, a lifetime license runs you just $2.99, with a license and donate option for $4.99. Overall, we’re quite impressed by QKSMS, even more so than last year. Definitely check this one out. Droid App
Otter is an innovative automatic recording and transcription service that works in real time. Simply hit the record button during a conversation or meeting and Otter will produce a usable transcript a few minutes later. Otter's app is fluid, well-designed, and quick in operation, which makes it ideal for students and professionals who rely on their mobile devices for their work. The app also integrates other top-notch features such as cross-conversation speaker identification, excellent search tools, and in-app editing of transcripts.
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
