# ReviewBook vs Protagonist

The clearest difference is update cadence: ReviewBook at every 2 days against Protagonist's every 2 weeks. Protagonist's advantage is ratings volume (35 vs 7). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. ReviewBook sells 1 one-off in-app purchase and Protagonist sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for ReviewBook against 5.0 for Protagonist. That said, the two scores are not equally well evidenced: Protagonist has 35 ratings behind it against 7, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

ReviewBook ships an update every 2 days, Protagonist every 2 weeks. Both last shipped on November 3, 2026.
