# Blink vs Posture Check

The clearest difference is ads: Blink at none against Posture Check's shown. Blink also leads on iOS requirement (17.0 vs 26.4). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Blink sells 1 one-off in-app purchase and Posture Check sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
