# Confidence Engine vs StreakFlow

The clearest difference is ads: Confidence Engine at none against StreakFlow's shown. StreakFlow's advantage is device support (4 vs 1) and iOS requirement (15.1 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. Confidence Engine sells 1 in-app purchase, starting at $1.99 per month and StreakFlow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
