# OnePrep vs Studley

The clearest difference is review sentiment: OnePrep at 88% against Studley's 50%. OnePrep also leads on in-app purchases (none vs 16) and rating (5.0 vs 4.7). Studley's advantage is ratings volume (4.4K vs 1). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Studley sells 12 in-app purchases, starting at $7.99 per 7 days. OnePrep asks for nothing beyond the download.

OnePrep holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Studley has 4.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 88% of OnePrep's written reviews are positive against 50% of Studley's.

OnePrep ships an update fortnightly, Studley weekly. The most recent releases landed on October 1, 2026 and October 14, 2026 respectively.
