Onion Browser helps you access the internet with more safety and privacy, and no extra cost to you. “The best Tor-related offering on iOS right now is Onion Browser” - The Daily Dot, October 14, 2015. Featured in: The New York Times, The Guardian, Salon, TechCrunch, Gizmodo, Boing Boing, Lifehacker, Macworld, The Daily Dot, & others.

If the app does not connect, try using bridges (or a different type of bridge), force-quit, and then restart the app. - Use of Onion Browser is at your own risk; remember that sensitive data does not always belong on a mobile device. ** Onion Browser is free and open-source software.
