ProtonVPN

Proton VPN is a Swiss-based VPN service built by the team behind Proton Mail — the same CERN scientists who created the world's largest encrypted email service in 2014. With 12,000+ servers across 120+ countries, it offers both a genuinely free tier (no ads, no logs, unlimited bandwidth) and a paid plan with streaming optimization, ad/tracker blocking (NetShield), and advanced routing through privacy-friendly countries (Secure Core). All apps are open source and the no-logs policy is independently audited with public reports. Rated 4.6 on both the App Store and Google Play.
