Slack has gone from the new hotness, to controversial productivity tool, to essential office tool faster than you can say "hot take." With a familiar, instant messenger feel, it's easy to get started with Slack. But the service became popular because of its wealth of advanced features, like customizable alerts and a Do Not Disturb function. You can even host VoIP calls through Slack with your coworkers. A free account will get you started, but a monthly fee unlocks even better search tools. And be sure to install the Giphy plugin for maximum productivity. Droid App
If you're looking to learn another language, Duolingo gamifies language learning with bite-sized lessons and a friendly interface. Starting with simple vocabulary and building from there, Duolingo is your guide to learning a new language or brushing up on one you already know. The more you use the app, the more you unlock and—with practice—the more you learn. This free app currently supports Danish, Dutch, French, German, Irish, Italian, Portuguese, Spanish, and Swedish. Or more practical choices, like Esperanto and Klingon.
What's also cool for 2019 is Uber's electric bicycle sharing system, JUMP. The JUMP bikes can be rented directly from the existing Uber app. There's no need to sign up for a new account, and your existing Uber payment method can be used. If the weather is nice, why not ride the route yourself! JUMP is only available in select regions at the moment but will be rolling out to more cities in 2019 and 2020.
Want to keep your internet activities on the down-low, or simply don’t like the idea that the government could be spying on your every move? One of the best Android VPN apps is a great way to prevent that. ExpressVPN offers both a virtual private network, and some advanced features — such as the ability to connect to servers in more than 100 locations around the world. Droid App
This is one seriously powerful app. It also works on most Android devices. You simply download the app and then enable it. From there, you can ask it whatever you want. It also supports a variety of commands. You can control lights, ask about population control, and it can even do simple math problems for you. There are a variety of products like Google, Bose QC II Bluetooth headphones, Home and Chromecast that extent the functionality even further. There is also a second Google Assistant app for those who want a quick launch icon on the home screen. The hardware stuff costs money, but Google Assistant is free. Amazon Alexa is another excellent app in this space, but it doesn’t support Google Android quite as much as we would like, yet. Android App
Nine is a very reliable email client designed to work with all of your accounts. The clean interface and the optional conversation view make reading and replying to email intuitive. One of the coolest features is the ability to customize the notification actions, including an incredibly useful "Mark as read" option. It isn't cheap, but it's only a one-time $14.99 charge for a much-improved email experience that also integrates calendar, contacts, notes, and tasks functionality.
There are a lot of apps out there that pay lip service to security and privacy, but Signal was built from the ground up with the goal of letting people easily communicate without having to worry about being overheard. The Signal app is a complete phone and SMS client replacement (though it works just fine as a standalone app, too) for sending and receiving encrypted calls and messages. A recent update has greatly improved the app's look and feel, proving that security and usability don't have to be at odds. New Droid Apps
Twitch is the best way to watch people play games or pursue their creative hobbies on your mobile device. From eSports to cooking to music and more, there's likely some content on Twitch that everyone can enjoy. If you are feeling generous, you can also support your favorite creators directly from the app. Twitch Prime members can also claim free games and in-game loot each month. Droid App
If an event isn't being organized on Facebook, it's probably being done through Eventbrite. This service makes it easy to manage invites, RSVPs, and even ticket purchasing. Attendees get handy reminders about the events they planned to attend, organizers can see guest lists. We particularly like that Eventbrite can generate QR codes, making event check-in a breeze.
Google Drive is a cloud storage solution available on Android where all new users get 15GB for free permanently upon signing up. You can, of course, buy more if needed. What makes Google Drive so special are the suite of Android apps that are attached to it. They include Google Docs, Google Sheets, Google Slides, Google Photos, Gmail, Google Calendar, and Google Keep. Between the office apps, the Photos app (which allows unlimited photo and video backup), and Keep Notes for note taking, you have apps for practically anything you need to do in terms of productivity. Some of the features of these apps include live collaboration, deep sharing features, and compatibility with Microsoft Office documents. Microsoft Office has a similar setup with OneDrive and Office.

File browsing is something everyone inevitably has (or wants) to do, so you might as well do it with a capable, fantastic file browser. Solid Explorer is pretty much as good as it gets in the file explorer apps realm. It features Material Design, archiving support, support for the most popular cloud services, and even some more power user stuff like FTP, SFPT, WebDav, and SMB/CIFS support. It looks great, it’s incredibly stable, and it just works well. There is a 14-day free trial with a $2.99 price tag at the end of it. This is, by far, the best file manager on Android for most people.
