Best VPN for iPhone: iOS Apps Ranked on Privacy, Security and Price

The top three on the same fields

Why X-VPN beats Proton VPN on this page

This page gives 35% weight to the ecosystem subindex: apps across platforms, split tunnelling, support. X-VPN scores 9.0 there, the highest of the three, which lifts it above Proton. The overall column uses standard weights, and on those Proton edges ahead (6.12 vs 6.05).

Where each leader loses points

X-VPN's weak spot is security (4.6): our data shows no confirmed security audit, though the service does carry an ISAE 3000 no-logs attestation, plus DNS leak handling never stated and apps not confirmed open source. Its bypass score of 1.9 reflects a single stealth mode with none of the censorship-grade protocols. Proton shares that bypass problem at 2.4, and its privacy mark of 6.0 drops because sign-up requires an email and connection IPs are kept temporarily for abuse checks. CitadelVPN's lowest marks are value (7.5) and platforms (7.6), and its 14-day refund window is less than half the 30 days the other two give.

What an iPhone VPN app has to get right

Every handover from Wi-Fi to mobile data risks dropping the tunnel, and a phone does this all day. The kill switch blocks traffic until the tunnel returns; without it, a request can slip out over the open network. 167 of the 411 services confirm one, and some ship it off by default, so check the toggle after install.

DNS leak protection keeps lookups inside the tunnel; on hotel or café Wi-Fi the hotspot resolver would otherwise see every site you open. Only 106 services confirm it. Split tunnelling is harder on iOS, because Apple ties per-app VPN to device management (MDM) and each provider builds its own workaround. Proton lists the feature on desktop platforms and Android, while iOS stays out of the list. Read the iOS field on a service's card rather than the headline feature grid.

Protocols: built-in client versus App Store app

The built-in client (Settings → General → VPN & Device Management) speaks IKEv2, L2TP over IPsec and Cisco IPsec. Apple's VPN overview explains that everything else, WireGuard included, runs inside an App Store app that relies on the Network Extension framework. WireGuard suits phones with its fast reconnects after a network change; on filtered networks, VLESS/Reality or Hysteria2 hold up where plain WireGuard gets dropped.

Setting a VPN up on iPhone

Install the provider's official app from the App Store, sign in, connect. The first connection triggers an "Add VPN Configurations" prompt; decline it and the app cannot open a tunnel. A manual IKEv2 profile goes in Settings → General → VPN & Device Management.

Paying through Apple or the provider directly

An in-app purchase hands billing, renewal and refunds to Apple; cancellation lives in Settings → your name → Subscriptions. Provider refund terms can be narrower: Proton refunds direct purchases within 30 days only, while X-VPN limits its 30-day window to Stripe, PayPal and Google Play, excluding crypto. 186 services auto-renew by default, and Proton renews at about twice the intro rate, so set a reminder before the first term ends. Cheapest plan runs €0.36 a month, median €3.00.

Free iPhone VPN apps

178 of the 411 services offer a free plan, and 78 of those confirm ads in the free tier. Proton's free plan gives unlimited data with no ads on one device. The free iPhone list shortlists the options.

App Store stars versus written reviews

App Store ratings are known for only 120 of the 411 services. X-VPN shows 4.66 stars in the US store, Proton 4.64, yet the written reviews the site collected average 3.55 and 3.46. Read the newest reviews before trusting the badge.

FAQ

Short answer

CitadelVPN first (8.43), X-VPN second (6.89), Proton VPN third (6.40); on the standard weights Proton passes X-VPN. Start from a stated no-logs policy: the no-logs iPhone list covers every service that publishes one, though only 31 of the 411 have an independent audit. Then confirm the kill switch and DNS leak protection, and read the renewal and refund terms before the first charge.
