# Estudei vs Cardflow

Estudei and Cardflow 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. Estudei sells 1 in-app purchase, starting at $39.99 per year and Cardflow sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
