# VO2 Max Training vs Matrix Training

The clearest difference is update cadence: VO2 Max Training at every 4 days against Matrix Training's every 2 months. Matrix Training's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. VO2 Max Training sells 6 in-app purchases, starting at $0.99 per month and Matrix Training sells 1 in-app purchase, starting at $399.00 per month. Whichever you choose, the download price is not the number that matters.
