Is there a good iOS app for a free VPN that's simple to use, even if it has some ads?

Betternet VPN is a contender for users seeking a no-cost, simplified virtual private network experience on iOS. The app's primary strength is its extreme ease of use: a prominent 'Connect' button establishes a VPN connection immediately, requiring no configuration or server selection. This makes it suitable for quick tasks like checking a website from a different region or adding a basic layer of security on a public Wi-Fi network. The free service is supported by video advertisements, which grant access in timed increments. For instance, a user might watch a 30 to 40-second ad to receive 15 to 30 minutes of VPN access. This model can be functional for intermittent, short-burst usage. However, reviews indicate the recent ad-to-usage ratio has become a significant point of criticism, with some users finding the frequency intrusive for the amount of service provided. The app also offers a premium, ad-free subscription with unlimited data and faster speeds. Specific features include a selection of virtual server locations and a basic no-logs policy. While reliable for light browsing, performance may not be consistent enough for data-intensive activities like HD video streaming on the free plan. For those with minimal, sporadic needs who don't mind the ad-supported trade-off, Betternet provides a functional solution.
