Some people get by for years without ever needing a file manager, while others find themselves needing one from day one. If you happen to be one of those people who need one, this is one that is packed with features, such as support for compressed files and password protection.
On top of being a local file manager, this is also a great cloud storage manager, with support for Dropbox, OneDrive, and Google Drive.
The best, most fully-featured camera app you can get for Android. If you want to be able to tweak a whole bunch of settings before pressing the capture button, this is the app for you. It's the closest you get to having a DSLR to play with while only having to carry your smartphone.
A totally anonymous VPN that keeps you safe on the internet, whether you are surfing over a cellular network or a free café Wi-Fi. Great speed, and unlimited bandwidth, along with robust privacy makes this a far better choice than a free VPN app (which can be dubious).
A nice, well-featured in-car navigation app. I like the simplicity of this app, and find that the way it presents my journey to be nice and easy on the mind. It also works with Android Auto, so it's a suitable replacement for Google Maps.
