# Numio vs 9

The clearest difference is ads: Numio at none against 9's shown. Numio also leads on iOS requirement (12.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Numio sells 1 in-app purchase, starting at $1.99 per month and 9 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
