Network Analyzer makes it easy to view information about all of the Wi-Fi networks nearby. With a few taps, you can see the strength of networks in the area on a dynamic graph and view detailed information about your connection, such as your IPv4 Address, MAC Address, and Default Gateway IP. You can even run a network query from within the app; it lets you Ping an IP/Domain Name or even check the DNS Server settings. It's the perfect companion to our article on how to find your IP address. Droid Apps
Musicolet is an intriguing option for local music playback. It does all of the basics, including playlists, tag editing, organizational features, file browsing, and embedded lryics (LRC) support. You also get an equalizer, a sleep timer, widgets, lock screen controls, Android Auto support, and more. It covers basically all standard use cases and it still piles more on top. In addition, it’s entirely free with no in-app purchases and no advertising. We also quite like the simple, effective UI.
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.
Though its interface is a bit tricky, Stitcher connects you with just about every podcast out there. Podcasts are organized by subject, or you can just search for a familiar title. Shows can, in turn, be organized into playlists for a continuous stream. Once you've exhausted all your favorites, let Stitcher recommend something new. With a special emphasis on sources like NPR, CNN, and ESPN, Stitcher has a little bit of everything.
The Google Drive suite are a group of applications that are all directly integrated into Google Drive. The apps include Google Docs, Google Slides, Google Sheets, Google Photos, and Google Keep along with the actual Google Drive app itself. These apps focus primarily on office use for documents, spreadsheets, and slideshows but also work for note taking, backing up your photos, and storing whatever file you can think of. The best part is that they’re all free unless you need more than 15GB of storage on Google Drive. Most people don’t. These are all great free Android apps. Droid App
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. Droid App
