# BioTrace vs Cortex

The clearest difference is update cadence: Cortex at every 11 days against BioTrace's every 6 months. BioTrace's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. BioTrace sells 4 in-app purchases, starting at $14.99 per month and Cortex sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

BioTrace ships an update every 6 months, Cortex every 11 days. Both last shipped on October 31, 2026.
