Surfing the web on a public WiFi can be dangerous business, opening your iPhone or iPad up to spying eyes. To avoid that, you could use a VPN to stay private and anonymous.

A VPN also hides your location online, which can allow you to access blocked content and blocked sites such as US Netflix when you are in the UK or BBC iPlayer when you are abroad. Here we talk you through the best iOS VPN options.

It's important to note that it is against Netflix, BBC iPlayer and other blocked content's terms and conditions to access them using a VPN, so proceed with caution as you risk getting your account blocked.

It's important to note that, as of 17 July, Apple has begun banning VPN-based ad blockers from the iOS App Store as part of its guidelines, as spotted by the developer behind Adblock and Weblock who has been affected by the ban.

However, the apps mentioned here are unaffected, and even those that have been affected will quickly adapt to ensure that they are allowed back onto the App Store and follow Apple's guidelines.

Additionally, VPNs have been banned in China and Russia, and as a result Apple has been removing VPN apps from the iOS App Store in those countries.

CyberGhost

CyberGhost

CyberGhost is another great option, and it's also brilliantly priced. It's headquartered in Romania, which is outside the 14-eyes group of countries that share signals intelligence (find out more here).

One of the great things about CyberGhost is its ease-of-use. It's simple and intuitive, and does lots of the hard work for you. There are more than 1000 servers available to connect to over 30 different countries, although they don't always work with Netflix US.

You can get CyberGhost for $2.90 per month if you sign up for two years (you'll pay $69.60 upfront), but if you want to commit to just one month it'll be $10.49 per month.

Private Internet Access

Private Internet Access

Private Internet Access is another of the best VPNs that also comes a low price tag.

At around £3 per month, it offers anonymous browsing and access to blocked content including Netflix US.

The iPhone and iPad app is incredibly simple and easy to use, and it's also super-speedy. A solid option.

IPVanish

IPVanish

Another option that offers lots of great features is IPVanish, which is both good-looking and easy to use. It has 750 servers in 60 countries.

It's going to appeal to beginners, as it's one of the most intuitive VPNs we've used, but it does have one downside and that is that it's located in the US. That's not a problem for most casual users, but if 100% privacy is your main concern then you might want to look elsewhere. The company does promise that it doesn't keep any logs, though.

IPVanish costs around £5 per month.
