# Big Numbers vs IOU

The clearest difference is rating: IOU at 5.0 against Big Numbers's 4.1. IOU also leads on review sentiment (100% vs 68%) and iOS requirement (15.1 vs 26.0). Big Numbers's advantage is ratings volume (36 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Big Numbers sells 2 in-app purchases, starting at $0.99 per 7 days and IOU sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

IOU holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Big Numbers has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 68% of Big Numbers's written reviews are positive against 100% of IOU's.
