# Book Progress vs Library Calculator

Book Progress and Library Calculator are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Book Progress sells 1 one-off in-app purchase and Library Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Book Progress ships an update every 6 weeks, Library Calculator monthly. The most recent releases landed on September 15, 2026 and July 19, 2026 respectively.
