# V.O2 vs Pace

The clearest difference is ads: V.O2 at none against Pace's shown. V.O2 also leads on update cadence (weekly vs every 6 weeks) and ratings volume (6.3K vs 386). On price, rating, review sentiment 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 Pace sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

V.O2 holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: V.O2 has 6.3K ratings behind it against 386, so its average is the more settled of the two. Written reviews complicate that: 71% of V.O2's written reviews are positive against 75% of Pace's, so the app with the better star average is not the one people write more warmly about.

V.O2 ships an update weekly, Pace every 6 weeks. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
