# Anvil vs Protocol 90

The clearest difference is monetization model: Protocol 90 at free with in-app purchases against Anvil's subscription. Protocol 90 also leads on ratings volume (19 vs 6) and iOS requirement (16.0 vs 26.2). Anvil's advantage is ads (none vs shown). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Anvil sells 2 in-app purchases, starting at $9.99 per month and Protocol 90 sells 7 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
