For those of us with limited data or slow internet speeds, Opera Max is one of the most-useful apps out there. Basically, the app uses compression to save you massive amounts of data when you use your smartphone, especially when using video streaming services like Netflix, and as of now, the app supports music streaming services as well. It works on both cellular networks and Wi-Fi, so you’re able to save data no matter how you’re connected to the Internet, and it even gives you a plethora of data management tools to customize how your smartphone consumes data.
