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. Android App

Tasker is a glorious application if you have the patience to learn how to use the app. What it does is allow users to create custom made commands and then use them in various places. There are many apps out there that have Tasker support and you can even use Tasker to create very complex commands for NFC tags. It’s difficult to truly explain what this app can do because it can do so many things. Between the apps supported, plugins you an add, and the sheer volume of stuff that you can do, there aren’t many apps out there as useful as this one. IFTTT is another excellent automation app. In some cases, it may even be better than Tasker thanks to its simplicity and wide range of uses.
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
