# Book Diary vs Po Book Tracker

Book Diary and Po Book Tracker are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement 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 Diary sells 1 in-app purchase, starting at $3.99 per month and Po Book Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
