Onion Browser is a free web browser for iPhone and iPad that encrypts and tunnels web traffic through the Tor network, with extra features to help you browse the internet privately. See more features & benefits.
December 1, 2016, price update: Onion Browser is now free. Read more about it here. If you'd like to support continuing development of Onion Browser and other Tor iOS projects, please consider backing the project on Patreon or donate via one of the other options.
November 30, 2016: Onion Browser is not affected by the recent zero-day exploit against Tor users. The exploit targets a Firefox bug and affects the desktop Tor Browser Bundle; Onion Browser is not affected because it is based on the iOS WebKit engine, rather than Firefox.
August 25, 2016, minor update: Onion Browser 1.6.2 is a minor update to Onion Browser that updates Tor to 0.2.8.7. Full details on this update and all prior updates can be found in the release history. Other details can be found in the Security page. Users are encouraged to update via App Store.
August 7, 2016; 1.6 series: Onion Browser 1.6 is a major update to Onion Browser. Onion Browser now supports obfs4 and meek bridges; these "obfuscated" bridges improve the usability of Tor if you are in an area that blocks Tor. This feature comes from the new iObfs library, which provides an iOS-compatible build of obfs4proxy. Special thanks to the Guardian Project for supporting continuing work on iObfs and Onion Browser.
