# Number Book vs Gulf Numbers

The clearest difference is review sentiment: Gulf Numbers at 100% against Number Book's 40%. Gulf Numbers also leads on rating (5.0 vs 4.4) and update cadence (every 2 months vs every 5 months). Number Book's advantage is ads (none vs shown) and ratings volume (48 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Number Book sells 5 in-app purchases, starting at $8.99 per 7 days and Gulf Numbers sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
