# Njn vs Ai Gravity

The clearest difference is ads: Ai Gravity at none against Njn's shown. Ai Gravity also leads on iOS requirement (17.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Njn sells 1 in-app purchase, starting at $14.99 per month and Ai Gravity sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
