# IntrustCA vs Tingbox

The clearest difference is review sentiment: IntrustCA at 100% against Tingbox's 50%. Tingbox's advantage is rating (4.8 vs 4.0) and ratings volume (51 vs 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.

Tingbox holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Tingbox has 51 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of IntrustCA's written reviews are positive against 50% of Tingbox's, so the app with the better star average is not the one people write more warmly about.

IntrustCA ships an update every 2 months, Tingbox fortnightly. Both last shipped on November 4, 2026.
