7. Orweb
This is the equivalent of the Tor browser and it needs Orbot in order to work correctly. Orweb is the most secure browser for the Android operating system, so if you’re keen on keeping stuff private, you’d better drop Chrome, Firefox or the stock browser in favor of it. Orweb also uses end to end encryption in order to hide any trace of your presence on the internet, which means that you won’t be tracked by websites or government agencies, at least not that easily. Orweb is popular because it can get around websites that are blocked on the network you are using, so if you’re a student or at the office, you can use Orweb to access some of those NSFW sites you’ve been jonesing for. But I’m not advising you to do so: school is for studying, work is for working, not for Facebook(ing). As usual, free in the Play Store.
