# Linus vs Proll

The clearest difference is ads: Proll at none against Linus's shown. Proll also leads on review sentiment (100% vs 68%) and monetization model (free vs free with in-app purchases). Linus's advantage is update cadence (every 11 days vs every 2 months) and ratings volume (797 vs 14). On price, rating, in-app purchases 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 and Proll sells 2 in-app purchases, starting at $3.99 per 7 days. 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 4.6 for Proll. That said, the two scores are not equally well evidenced: Linus has 797 ratings behind it against 14, 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 Proll's.

Linus ships an update every 11 days, Proll every 2 months. Both last shipped on October 24, 2026.
