Eve also boasts a vibrant community and a wealth of information about sexual health built right in.
Streaming services are all the rage, but if you still keep music locally, BlackPlayer is worth your attention. We particularly like the Discover option, which shuffles through 10-second previews of seldom-played tracks in your library continuously, until you decide on what to listen to next. There's also a built-in tag editor and a ton of customization options for button styles, fonts, themes, and now playing notifications. Android 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
