# Presentation Mobile vs Booster Prep

The clearest difference is review sentiment: Presentation Mobile at 100% against Booster Prep's 59%. Presentation Mobile also leads on in-app purchases (none vs 11) and iOS requirement (12.0 vs 15.1). Booster Prep's advantage is update cadence (fortnightly vs every 14 months) and ratings volume (721 vs 2). On price, ads and device support there is nothing between them.

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

Booster Prep holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Booster Prep has 721 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Presentation Mobile's written reviews are positive against 59% of Booster Prep's, so the app with the better star average is not the one people write more warmly about.

Presentation Mobile ships an update every 14 months, Booster Prep fortnightly. The most recent releases landed on September 29, 2026 and October 14, 2026 respectively.
