Appears genuine; be aware of iOS limitations – Onion Browser Review

As far as I can research, this appears to be a genuine open source port of a tor-tunneled browser to iOS. There exists an article on Ars Technica, but more importantly, Onion Browser is linked as a recommendation on the Tor Project download page, as an alternative for iOS users. I suspect the reason it has not been fully adopted by the Tor Project, as an official Tor Browser Bundle, is due to certain unavoidable issues with iOS causing IP address leakage - the Onion Browser website currently lists an issue with iOS’ handling of OCSP, and WebRTC, both potentially leaking data outside of the Tor connexion. Perhaps we will have an alternative when iCEPA (Tor on iOS via VPN API) is completed. As far as more easily solvable problems go, I think it is worth mentioning that the default User Agent does not match that of the Firefox ESR branch as done by TBB; perhaps that is intentional, to reduce the fingerprinting uniqueness of a WebKit browser masquerading as a Gecko one, but I think this should have been explained to the user in the setting description. Also, the Global Settings option for “Privacy - open in Settings app” does nothing, merely switching to Settings, without opening a specific preference panel/pane.
