# OneBook vs HeyReader

The clearest difference is monetization model: HeyReader at free against OneBook's freemium. HeyReader also leads on update cadence (every 3 days vs weekly). OneBook's advantage is ratings volume (64 vs 3) and iOS requirement (15.0 vs 18.0). On price, rating, review sentiment 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 HeyReader sells 2 in-app purchases, starting at $4.99 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 HeyReader. That said, the two scores are not equally well evidenced: OneBook has 64 ratings behind it against 3, 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 100% of HeyReader's.

OneBook ships an update weekly, HeyReader every 3 days. Both last shipped on November 5, 2026.
