# SAT® vs Linus

The clearest difference is in-app purchases: SAT® at none against Linus's 14. SAT® also leads on ads (none vs shown) and review sentiment (77% vs 68%). Linus's advantage is update cadence (every 11 days vs every 2 months). On price, rating, ratings volume and device support there is nothing between them.

Both are free to download. Linus sells 14 in-app purchases, starting at $24.99 per 3 months. SAT® asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for SAT® against 4.8 for Linus. Both are backed by a comparable volume of ratings — 1.7K and 759 respectively. Written reviews are what separate them: 77% of SAT®'s written reviews are positive against 68% of Linus's.

SAT® ships an update every 2 months, Linus every 11 days. The most recent releases landed on September 29, 2026 and September 22, 2026 respectively.
