# Metabo vs Hollow

The clearest difference is ads: Metabo at none against Hollow's shown. Metabo also leads on device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Metabo sells 4 in-app purchases, starting at $5.99 per 7 days and Hollow sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
