# Linus vs Sharp SAT Prep

The clearest difference is ads: Sharp SAT Prep at none against Linus's shown. Sharp SAT Prep also leads on review sentiment (100% vs 68%). Linus's advantage is ratings volume (759 vs 45). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Linus sells 14 in-app purchases, starting at $24.99 per 3 months and Sharp SAT Prep sells 3 in-app purchases, starting at $17.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Linus against 4.8 for Sharp SAT Prep. That said, the two scores are not equally well evidenced: Linus has 759 ratings behind it against 45, so its average is the more settled of the two. Written reviews are what separate them: 68% of Linus's written reviews are positive against 100% of Sharp SAT Prep's.

Linus ships an update every 11 days, Sharp SAT Prep every 3 weeks. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
