# TSI vs TSI Test Prep

The clearest difference is rating: TSI at 4.2 against TSI Test Prep's 3.0. TSI also leads on update cadence (monthly vs every 82 months) and ratings volume (31 vs 1). On ads, in-app purchases and device support there is nothing between them.

TSI costs $2.99 and TSI Test Prep $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

TSI holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: TSI has 31 ratings behind it against 1, so its average is the more settled of the two.

TSI ships an update monthly, TSI Test Prep every 82 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
