# CFR 39 vs BookWatch

The clearest difference is ads: CFR 39 at none against BookWatch's shown. CFR 39 also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.7). BookWatch's advantage is update cadence (every 3 days vs every 12 months) and ratings volume (14K vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. CFR 39 sells 3 one-off in-app purchases and BookWatch sells 22 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

CFR 39 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: BookWatch has 14K ratings behind it against 1, so its average is the more settled of the two.

CFR 39 ships an update every 12 months, BookWatch every 3 days. The most recent releases landed on October 6, 2026 and October 26, 2026 respectively.
