# OnePrep vs ACT Practice Exam Test Prep

The clearest difference is update cadence: OnePrep at every 5 days against ACT Practice Exam Test Prep's every 6 months. OnePrep also leads on ratings volume (701 vs 4). ACT Practice Exam Test Prep's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OnePrep sells 23 in-app purchases, starting at $28.49 per 7 days and ACT Practice Exam Test Prep sells 3 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ACT Practice Exam Test Prep holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OnePrep has 701 ratings behind it against 4, so its average is the more settled of the two.

OnePrep ships an update every 5 days, ACT Practice Exam Test Prep every 6 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
