# Spaced Repetition vs Learning Cortex

Spaced Repetition and Learning Cortex 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. Spaced Repetition sells 2 in-app purchases, starting at $1.99 per 7 days and Learning Cortex sells 1 in-app purchase, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
