# Book Writer One vs Ruby

The clearest difference is review sentiment: Ruby at 100% against Book Writer One's 44%. Ruby also leads on rating (5.0 vs 2.5). Book Writer One's advantage is ratings volume (16 vs 1) and iOS requirement (11.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Book Writer One sells 1 one-off in-app purchase and Ruby sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Ruby holds the better App Store score, 5.0 against 2.5. That said, the two scores are not equally well evidenced: Book Writer One has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 44% of Book Writer One's written reviews are positive against 100% of Ruby's.

Book Writer One ships an update every 3 weeks, Ruby monthly. The most recent releases landed on October 15, 2026 and October 13, 2026 respectively.
