# Hambook vs DoBuff

The clearest difference is update cadence: DoBuff at weekly against Hambook's every 6 weeks. DoBuff also leads on ratings volume (39 vs 3) and iOS requirement (17.0 vs 26.0). Hambook's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Hambook sells 3 one-off in-app purchases and DoBuff sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Hambook holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: DoBuff has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Hambook ships an update every 6 weeks, DoBuff weekly. The most recent releases landed on October 8, 2026 and October 6, 2026 respectively.
