# OnePrep vs AI Tutor

The clearest difference is in-app purchases: OnePrep at none against AI Tutor's 15. OnePrep also leads on review sentiment (88% vs 65%) and rating (5.0 vs 4.8). AI Tutor's advantage is ratings volume (1.2K vs 1). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. AI Tutor sells 14 in-app purchases, starting at $4.99 per 7 days. OnePrep asks for nothing beyond the download.

OnePrep holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: AI Tutor has 1.2K 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 65% of AI Tutor's.

OnePrep ships an update fortnightly, AI Tutor every 8 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
