Verdict

The call

The clearest difference is rating: Billdu at 4.8 against Quotation Book's 3.0. Billdu also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (26K vs 2). Quotation Book's advantage is review sentiment (100% vs 90%) and iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Billdu sells 10 in-app purchases, starting at $7.99 per month and Quotation Book sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Billdu holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Billdu has 26K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 90% of Billdu's written reviews are positive against 100% of Quotation Book's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Billdu ships an update every 2 weeks, Quotation Book every 3 months. The most recent releases landed on October 25, 2026 and October 16, 2026 respectively.
