# Billdu vs Quotation Book

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.

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.

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.
