# OneBook vs DexSpeak

The clearest difference is ratings volume: OneBook at 64 against DexSpeak's 9. OneBook also leads on iOS requirement (15.0 vs 18.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. OneBook sells 2 in-app purchases, starting at $8.00 per month and DexSpeak sells 3 in-app purchases, starting at $7.99 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 DexSpeak. That said, the two scores are not equally well evidenced: OneBook has 64 ratings behind it against 9, 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 DexSpeak's.

OneBook ships an update weekly, DexSpeak every 9 days. Both last shipped on November 5, 2026.
