# Sigma VPN vs VPN Fast Smart & Secure Proxy

The clearest difference is rating: VPN Fast Smart & Secure Proxy at 4.6 against Sigma VPN's 3.5. VPN Fast Smart & Secure Proxy also leads on update cadence (every 6 weeks vs every 3 months) and ratings volume (78 vs 15). Sigma VPN's advantage is in-app purchases (none vs 9) and review sentiment (50% vs 25%). On price, ads and device support there is nothing between them.

Both are free to download. VPN Fast Smart & Secure Proxy sells 9 in-app purchases, starting at $6.99 per month. Sigma VPN asks for nothing beyond the download.

VPN Fast Smart & Secure Proxy holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: VPN Fast Smart & Secure Proxy has 78 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 50% of Sigma VPN's written reviews are positive against 25% of VPN Fast Smart & Secure Proxy's, so the app with the better star average is not the one people write more warmly about.

Sigma VPN ships an update every 3 months, VPN Fast Smart & Secure Proxy every 6 weeks. Both last shipped on November 3, 2026.
