Tigas sensibly warns that versions of his app downloaded from outside the iOS App Store might have been tampered with, and that users should exercise caution if they cannot get their hands on the app through official channels.

(In many cases, this is due to possessing a grey market iPhone in a country where it’s unusual to have a payment method accepted by the App Store.) For censorship-circumventing software like Tor, barriers to access are a significant human rights issue – especially in the face of escalating digital repression in some parts of the world. …selling an app inherently puts up a barrier to user adoption – not for users who simply don’t want to pay for software, but rather for those users who cannot pay for the software. And that seems to be one of the motivations for no longer charging for the Tor browser he developed for iPhones and iPads: Tigas clearly feels passionately in empowering people’s ability to improve their digital security.
