# Certpia vs T ID

The clearest difference is review sentiment: T ID at 57% against Certpia's 13%. Certpia's advantage is rating (4.4 vs 1.0) and ratings volume (37 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Certpia holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Certpia has 37 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 13% of Certpia's written reviews are positive against 57% of T ID's, so the app with the better star average is not the one people write more warmly about.

Certpia ships an update monthly, T ID every 2 months. The most recent releases landed on September 25, 2026 and September 10, 2026 respectively.
