# V.O2 vs PaceMaster

The clearest difference is update cadence: V.O2 at weekly against PaceMaster's every 3 months. V.O2 also leads on ratings volume (6.3K vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. V.O2 sells 16 in-app purchases, starting at $12.99 per month and PaceMaster sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for V.O2 against 5.0 for PaceMaster. That said, the two scores are not equally well evidenced: V.O2 has 6.3K ratings behind it against 1, so its average is the more settled of the two.

V.O2 ships an update weekly, PaceMaster every 3 months. The most recent releases landed on October 26, 2026 and October 11, 2026 respectively.
