# VO2 Max vs Runner Strength

The clearest difference is ratings volume: VO2 Max at 131 against Runner Strength's 1. VO2 Max also leads on monetization model (free with in-app purchases vs paid) and device support (3 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. VO2 Max sells 3 in-app purchases, starting at $2.99 per month and Runner Strength sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Runner Strength holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: VO2 Max has 131 ratings behind it against 1, so its average is the more settled of the two.

VO2 Max ships an update every 2 weeks, Runner Strength every 9 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
