# V.O2 vs Runner's Tools

The clearest difference is update cadence: V.O2 at every 6 days against Runner's Tools's every 38 months. V.O2 also leads on ratings volume (6.2K vs 3). Runner's Tools's advantage is review sentiment (100% vs 71%) and monetization model (free vs free with in-app purchases). 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 Runner's Tools sells 1 one-off in-app purchase. 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 Runner's Tools. That said, the two scores are not equally well evidenced: V.O2 has 6.2K ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 71% of V.O2's written reviews are positive against 100% of Runner's Tools's.

V.O2 ships an update every 6 days, Runner's Tools every 38 months. The most recent releases landed on September 26, 2026 and September 3, 2026 respectively.
