Fill up your phone or tablet with the best Android apps around – now with to pick from!. So instead I present this list, the essential apps that you need, whether you're on the best and newest Android phone or still plodding along. Got a Samsung Galaxy S7, OnePlus 3T or any other Android device? Then you need to download these 40 free apps. Google Maps virtually owns the navigation apps scene and it remains of the best Android apps. It's all controlled with a master password. You can also use this service to send and receive faxes from your email client of choice. But everything you send and receive, including media, is encrypted and Threema's servers store as little information as possible, with contacts lists managed from your own device and messages deleted from the servers as soon as they've been delivered. It's ideal for making to-do lists, grocery lists, or lists shared with friends and family.
