# Optimism vs Polylith

Optimism and Polylith 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. Optimism sells 1 in-app purchase, starting at $6.99 per month and Polylith sells 3 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.
