# Web PKI vs Digi Iguá

The clearest difference is rating: Digi Iguá at 4.9 against Web PKI's 1.0. Digi Iguá also leads on update cadence (every 4 weeks vs every 2 months) and ratings volume (42 vs 4). Web PKI's advantage is review sentiment (30% vs 17%) and iOS requirement (8.2 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Digi Iguá holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: Digi Iguá has 42 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 30% of Web PKI's written reviews are positive against 17% of Digi Iguá's, so the app with the better star average is not the one people write more warmly about.

Web PKI ships an update every 2 months, Digi Iguá every 4 weeks. The most recent releases landed on October 8, 2026 and October 18, 2026 respectively.
