# Cram Crew vs OnePrep

The clearest difference is review sentiment: Cram Crew at 100% against OnePrep's 45%. Cram Crew also leads on in-app purchases (none vs 23) and ads (none vs shown). OnePrep's advantage is ratings volume (673 vs 8) and update cadence (every 5 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. OnePrep sells 23 in-app purchases, starting at $28.49 per 7 days. Cram Crew asks for nothing beyond the download.

Cram Crew holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OnePrep has 673 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 100% of Cram Crew's written reviews are positive against 45% of OnePrep's.

Cram Crew ships an update every 2 weeks, OnePrep every 5 days. The most recent releases landed on October 2, 2026 and October 21, 2026 respectively.
