# Preptly vs Linus

The clearest difference is review sentiment: Linus at 68% against Preptly's 28%. Linus also leads on rating (4.8 vs 4.3) and update cadence (every 11 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Preptly sells 11 in-app purchases, starting at $5.99 per 7 days and Linus sells 14 in-app purchases, starting at $24.99 per 3 months. Whichever you choose, the download price is not the number that matters.
