# OneBook vs Reloop

The clearest difference is ratings volume: OneBook at 64 against Reloop's 2. OneBook also leads on review sentiment (97% vs 84%) and iOS requirement (15.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. OneBook sells 2 in-app purchases, starting at $8.00 per month and Reloop sells 5 in-app purchases, starting at $1.99 per month. 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 OneBook against 5.0 for Reloop. That said, the two scores are not equally well evidenced: OneBook has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 97% of OneBook's written reviews are positive against 84% of Reloop's.

Both ship on a similar rhythm, roughly weekly. Both last shipped on November 5, 2026.
