# Supernotes vs Curio

Supernotes and Curio are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases 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. Supernotes sells 3 in-app purchases, starting at $11.00 per month and Curio sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
