Based on former Olympian, author, and legendary running coach Jack Daniels’ exercise science principles, the methodology not only benefits runners of all ages and abilities when it comes to improving their running fitness but it also serves as the best measure of running economy across a variety of runners and events, making it an ideal way to compare performances. High-school, college, Olympic and non-elite runners have all trained, ran, and succeeded with the VDOT methodology. -”Dr. Jack Daniels has had a bigger influence on training-for-running than anyone. He might be considered the Albert Einstein of the sport." - Runner’s World Magazine

Verdict
V.O2 and Fitnesse both sit at 4.9 stars, but that hides the real split: 100% of Fitnesse's written reviews are positive against 71% of V.O2's. V.O2's advantage is ratings volume (6.3K vs 46) and update cadence (weekly vs every 3 weeks). 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 Fitnesse sells 2 in-app purchases, starting at $12.99 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 Fitnesse. That said, the two scores are not equally well evidenced: V.O2 has 6.3K ratings behind it against 46, 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 Fitnesse's.
V.O2 ships an update weekly, Fitnesse every 3 weeks. The most recent releases landed on October 19, 2026 and October 13, 2026 respectively.
