# Sharp SAT Prep vs OnePrep

Sharp SAT Prep and OnePrep both sit at 4.8 stars, but that hides the real split: 100% of Sharp SAT Prep's written reviews are positive against 45% of OnePrep's. Sharp SAT Prep also leads on ads (none vs shown). OnePrep's advantage is update cadence (every 5 days vs every 3 weeks) and ratings volume (378 vs 45). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sharp SAT Prep sells 3 in-app purchases, starting at $17.99 per month and OnePrep sells 23 in-app purchases, starting at $28.49 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Sharp SAT Prep against 4.7 for OnePrep. That said, the two scores are not equally well evidenced: OnePrep has 378 ratings behind it against 45, so its average is the more settled of the two. Written reviews are what separate them: 100% of Sharp SAT Prep's written reviews are positive against 45% of OnePrep's.

Sharp SAT Prep ships an update every 3 weeks, OnePrep every 5 days. The most recent releases landed on September 21, 2026 and October 1, 2026 respectively.
