# Linus vs OnePrep

Linus and OnePrep both sit at 4.8 stars, but that hides the real split: 68% of Linus's written reviews are positive against 41% of OnePrep's. OnePrep's advantage is update cadence (every 5 days vs every 11 days). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Linus sells 14 in-app purchases, starting at $24.99 per 3 months and OnePrep sells 24 in-app purchases, starting at $28.49 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 4.7 for OnePrep. Both are backed by a comparable volume of ratings — 797 and 714 respectively. Written reviews are what separate them: 68% of Linus's written reviews are positive against 41% of OnePrep's.
