# VO2 Max vs VO2 Max Training

The clearest difference is review sentiment: VO2 Max Training at 100% against VO2 Max's 27%. VO2 Max Training also leads on rating (4.6 vs 3.8) and update cadence (every 4 days vs every 2 weeks). VO2 Max's advantage is ratings volume (131 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VO2 Max sells 3 in-app purchases, starting at $2.99 per month and VO2 Max Training sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
