# 2FA vs この電話、誰？

The clearest difference is ads: この電話、誰？ at none against 2FA's shown. 2FA's advantage is iOS requirement (16.4 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 2FA sells 2 in-app purchases, starting at $0.99 per 7 days and この電話、誰？ sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
