# PSI Test Prep vs Digi Chompers

The clearest difference is update cadence: Digi Chompers at every 4 days against PSI Test Prep's every 5 weeks. Digi Chompers also leads on iOS requirement (13.0 vs 16.4). PSI Test Prep's advantage is ratings volume (4.3K vs 1) and chart position (#200 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. PSI Test Prep sells 20 one-off in-app purchases and Digi Chompers sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Digi Chompers holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PSI Test Prep has 4.3K ratings behind it against 1, so its average is the more settled of the two.

PSI Test Prep ships an update every 5 weeks, Digi Chompers every 4 days. The most recent releases landed on October 22, 2026 and October 16, 2026 respectively.
