# Countdown Timer vs Duet AI

The clearest difference is ads: Duet AI at none against Countdown Timer's shown. Countdown Timer's advantage is device support (3 vs 1) and iOS requirement (12.3 vs 17.6). On price and in-app purchases there is nothing between them.

Both are free to download. Countdown Timer sells 2 in-app purchases, starting at $0.99 per month and Duet AI sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
