Surfshark vs Proton VPN: which iOS VPN deserves your subscription?

A VPN is one of the few App Store categories where the marketing screenshots tell you almost nothing. Every app in the aisle promises speed, security, and a glowing shield icon. The differences that matter show up somewhere else entirely: who builds the app, where the company is legally based, and what actually happens the second you tap connect. Surfshark VPN: Fast VPN App and Proton VPN: Fast & Secure are two of the most credible names on iOS. Both are free to download, both sit on large piles of positive ratings, and both arrive at the same job from opposite ends of the philosophy spectrum. Here is the honest head-to-head, plus where two strong alternatives fit around them.

Two different reasons these apps exist

Surfshark carries a 4.71 average across more than 121,000 ratings, which is one of the strongest sustained signals in the whole VPN category. It is a consumer-first product: a fast connect button, clean design, streaming that mostly just works, and a headline feature of unlimited simultaneous devices on a single plan. That last point is the quiet reason a lot of households pick it. You install it on the phone, the partner's phone, the tablet, and the laptop without counting seats.

Proton VPN sits at 4.61 and comes from Proton AG, the Swiss team behind ProtonMail. That lineage is the whole pitch. Proton treats privacy as an identity rather than a feature list: its apps are open source, it publishes transparency reporting, and it operates under Swiss jurisdiction, which is genuinely friendlier to user data than most. It is also the rare name here with a real, no-cost tier that does not cap your data, which makes it the natural starting point for anyone who wants to try a serious VPN before paying a cent. The caveat is that the free tier limits you to a small set of countries, so the free experience is a taste, not the full product.

Speed and the everyday experience

Both apps put "fast" in their store name, and honestly both are quick enough that most people will never notice the tunnel is on during normal browsing. The difference is texture. Surfshark's app is tuned for the mainstream: connect, forget, watch something. It leans into the extras a typical user wants, like built-in ad and tracker blocking, and it rarely asks you to understand what a protocol is.

Proton's app is denser. You get granular server selection, secure-core routing that bounces traffic through hardened privacy-friendly countries, and options that a careful user will love and a casual user may find like homework. Secure-core protection can add latency, which is the expected trade for a harder-to-trace path. Neither app is slow in any meaningful sense; the question is whether you want the invisible experience or the control panel. We will not quote benchmark numbers here, because real-world VPN speed depends heavily on your own connection, the server you land on, and the time of day.

Privacy posture and who you are trusting

This is where the two genuinely separate. Surfshark advertises a no-logs policy, runs its fleet on RAM-only servers so nothing persists through a reboot, and has submitted to independent audits. That is a solid, modern posture and there is no reason to be suspicious of it. Worth knowing for the paranoid: Surfshark is part of the same corporate family as NordVPN, so if you want your VPN and your fallback to be run by fully separate companies, that matters.

Proton's advantage is that transparency is the brand, not a marketing bolt-on. Open-source apps mean the code can be inspected rather than trusted on faith, and the Swiss base gives it a legal footing built around data protection. If your threat model is serious, or you simply want the provider whose entire business would collapse if it quietly logged you, Proton is the more reassuring pick. For most people the two are both trustworthy; the gap is about how much of that trust you can independently verify.

Where NordVPN and PIA fit in

NordVPN: VPN Fast & Secure holds a 4.66 average and remains one of the most downloaded VPN apps on iOS for a reason: it pairs a very large server network with its own fast NordLynx protocol. If your priority is raw server choice and a name your relatives already recognize, Nord is the obvious cross-shop against Surfshark, though remember the two share a parent company.

VPN by Private Internet Access sits at 4.69 and is the enthusiast's choice. PIA is US-based, which sounds like a strike against it, but it has a court-tested history of having no logs to hand over, and its app is unusually configurable for people who like to tune every setting. It also offers unlimited devices, so it competes directly with Surfshark on that front for the tinkerer who wants knobs rather than a single button.

The verdict: pick this if

Pick Surfshark if you want the smoothest mainstream VPN, cover an entire household on one plan thanks to unlimited devices, and value a connect-and-forget experience with streaming and ad blocking baked in. Its rating and review volume back up the "it just works" reputation.

Pick Proton VPN if trust is the deciding factor: open-source apps, Swiss jurisdiction, and a genuinely usable free tier make it the pick for privacy-serious users and for anyone who wants to test a real VPN at no cost first. If you land in the middle, cross-shop NordVPN for the biggest network and PIA for maximum control on a budget. All four are free to download, so the low-risk move is to install your top two and keep the one that feels right on your own connection.
