The best VPN apps for free are ones that do not slap on limits and restrictions to try to nag you to upgrade. Proton VPN Free, for example, is at the top of my list because it offers an excellent mix of features, power and app quality that doesn't limit data usage or showing ads. Its dedicated geoblocking staff makes it one of only free options data encryption to consistently unblock Netflix or BBC iPlayer. It also maintains the essential privacy features such as WireGuard and content blocking, unlike many other free providers.

TunnelBear is another top free VPN application. It offers user-friendly applications and is able to maintain a good speed and allows you to use 2GB of data per month. However, its data collection policy is alarming as it logs the region codes, the browsing activity as well as other data that could lead to online monitoring. Psiphon is another popular option but it also records more concerning information, like timestamped browsing activities and information about the device, and also shares user data with commercial partners.

CyberGhost is another great free option. It is a simple app and navigation. The "Best Server Location" feature will automatically select the fastest connection for you, or you can select a particular country. Its security is also impressive with leak protection that is complete RAM-only servers, as well as flawless forward secrecy. It also has an audited no-logs security policy and an effective tracker blocker. The only downside is that it only supports 1 device at a time.
