# Booster Prep vs OneScreen

The clearest difference is review sentiment: OneScreen at 100% against Booster Prep's 61%. OneScreen also leads on in-app purchases (none vs 11) and rating (5.0 vs 4.8). Booster Prep's advantage is ratings volume (721 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Booster Prep sells 7 one-off in-app purchases. OneScreen asks for nothing beyond the download.

OneScreen holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Booster Prep has 721 ratings behind it against 1, so its average is the more settled of the two.
