# Hidden Numbers vs Pi

The clearest difference is ads: Pi at none against Hidden Numbers's shown. Hidden Numbers's advantage is iOS requirement (12.0 vs 16.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Hidden Numbers sells 1 one-off in-app purchase and Pi sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
