Our Verdict

A wonderful option to quickly switch between any of the dozens of Public DNS services.


  • Extensive list
  • No in-app adverts


  • No categories

There’s no dearth of public DNS services that are better than your ISPs DNS solution in terms of features, security and privacy. While switching your DNS provider doesn’t take much doing, the process isn’t as straightforward for inexperienced users, especially on mobile devices. 

The popular VPN provider Surfshark offers a free DNS changer app that you can use to switch to another DNS service with a single tap.


In addition to its VPN service, Surfshark also runs a public DNS service called Trust DNS. The service encrypts all your DNS queries with either the DNS-over-HTTPS (DoH) or the DNS-over-TLS (DoT) protocols. The use of these protocols ensures your ISP can’t track your movements across the Internet.

Surfshark also has a no-logs policy and doesn’t store any of your data nor does it log your online activities. In fact you can get started with the service without registering withSurfshark. On top of it, the free DNS changer app doesn’t display any advertisements. You do get the occasional reminder to checkout Surfshark’s VPN service, but you’ll never see a third-party advert.

You can switch to Trust DNS using the DNS changer app. By default it uses the version of the service that uses the DoH encryption protocol. But you can switch to the Trust DNS version that uses the DoT protocol to create the encrypted channel for ferrying DNS queries.

In addition to its own DNS servers, the DNS changer app also lists dozens of other public DNS services. It includes all the popular ones such as Google Public DNS, Cloudflare, Quad9, CleanBrowsing, NextDNS along with several esoteric ones that serve a particular use case.

Again, just like with the Trust DNS service, you can use Surfshark’s DNS changer app without registering with the service. Note however that while Surfshark’s Trust DNS service only supports IPv4 networks, the app lists several other services that support the IPv6 networks as well.

Interface and Use

Using the app is pretty straightforward. Just grab it from Google’s PlayStore or Apple’s App Store and install it on your Android or iOS device. The process doesn’t require any registration, so you can push the app into active duty straight after installation.

The DNS changer app has a simple layout, with three buttons. Tap the Power button in the middle to switch to the selected DNS service. By default, this is the DoH-equipped Trust DNS service. On first launch you’ll be asked to give the app permission to create a VPN connection. The service needs this to create a VPN tunnel in order to change the DNS settings on the device.

If you’d like to switch to another DNS service, tap the DNS changer icon. This will show a list of several public DNS services along with a brief description to help you determine the purpose of the service. Scroll through the list and tap on the service you want to use. 

The app will then show you more details about the service including the security protocol it uses by default along with the features it supports to help you make an informed decision about using the service.

After reviewing the details, tap on Activate to switch to the service. The app will ask you for permission to force the app to re-establish the VPN connection and change your DNS settings.

The competition

The DNS Changer app doesn’t have a direct competition as such, but it does offer some advantages over directly modifying the DNS servers in your device. For starters, it does a nice job of incorporating the public services. For instance, Quad9 has a bunch of DNS services and you can access them all from the DNS changer app including both the IPv4 and IPv6 ones. 

In case the app doesn’t offer a particular service, you can roll them in yourself using the Add custom server option. Just enter its name and IP address in the space provided and you’re good to go. You can then switch to the service with a single tap instead of navigating the Android/iOS System settings to change the DNS settings manually.

It has services that’ll protect you from phishing, malware, ransomware, and malicious domains (Cloudflare Security, CleanBrowsing Security), filter ads (Adguard DNS, BlahDNS), and inappropriate content (Cloudflare Family, CleanBrowsing Family). You can save yourself quite a lot of time switching between them using the app rather than making the changes manually.

Final Verdict

The DNS changer app is all about convenience. While it has an impressive list of DNS servers, the long list can intimidate new users. A categorized list will definitely make it more digestible. 

That said, the list of DNS services are searchable by tags or by the name of the service and you can even mark certain servers as favorites, and switch between them easily. Considering the fact that it doesn’t require any registration, nor does it display any in-app adverts, we’d suggest you install the app on your Android or iOS device and experience its convenience.
