# Stackd vs Dopamine

Stackd and Dopamine are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

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