# PerfectPrep vs ACT Prep

The clearest difference is ads: ACT Prep at none against PerfectPrep's shown. ACT Prep also leads on review sentiment (80% vs 67%). PerfectPrep's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (883 vs 207). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. PerfectPrep sells 9 in-app purchases, starting at $4.99 per 7 days and ACT Prep sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for PerfectPrep against 4.7 for ACT Prep. Both are backed by a comparable volume of ratings — 883 and 207 respectively. Written reviews are what separate them: 67% of PerfectPrep's written reviews are positive against 80% of ACT Prep's.

PerfectPrep ships an update fortnightly, ACT Prep every 3 months. The most recent releases landed on September 23, 2026 and September 15, 2026 respectively.
