Onion Browser Description
Onion Browser is the original free and open-source Tor-powered web browser for iOS. 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.

FEATURES:
• Browse the internet over Tor:
- Protect your privacy from website tracking
- Secure your traffic from insecure wireless networks and ISPs
- Access .onion sites that are only accessible over Tor.

• Fight online tracking: block scripts and automatically clear cookies and tabs, based on your preferences.

• And more privacy-enhancing features!

DISCLAIMERS:
- Web browsing is much slower than through a normal web browser or a VPN because your traffic is encrypted and relayed through the Tor network.

- Onion Browser might not work on networks with advanced network restrictions. 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. You can read more about Onion Browser and how to support development of Tor on iOS by visiting onionbrowser.com **

---

Most importantly, Onion Browser now supports "pluggable transports" like obfs4 and meek, which improve connection support in locations that try to block Tor, thanks to the new "iObfs" library. See the Onion Browser official site for more information about the iObfs library. (Special thanks to the Onion Browser beta testers for their feedback on this new feature. Extra special thanks to The Guardian Project for supporting work on iObfs!)

(NOTE: there is a known incompatibility issue with beta versions of iOS. A workaround is being developed, but note that we do not provide official support for users on beta versions of iOS. You should not update if you are running an iOS beta.)

This is a major update to Onion Browser, which improves the Tor accessibility, performance, and overall security of Onion Browser. New features:

* iObfs: Onion Browser now supports "pluggable transports" like obfs4 and meek, which improve connection support in locations that try to block Tor. See the Onion Browser website for more information about the iObfs library. (Special thanks to the Onion Browser beta testers for their feedback on this new feature. Extra special thanks to The Guardian Project for supporting work on iObfs!)

* "One-click" bridge UI: Onion Browser now comes with built-in bridges for obfs4, meek-amazon, and meek-azure -- same the official Tor Browser Bundle and Orbot.

* User-agent spoofing strings updated to the most recent browser versions.

* Tor updated to 0.2.8.6, the first stable release in the 0.2.8 series. This version contains several performance and security improvements.

* OpenSSL updated to 1.0.2h.

* Minimum required iOS version is now iOS 8.2.
