The official VDOT Running Calculator, designed by Dr. Jack Daniels - named World's Best Running Coach by Runner's World Magazine - and the team at VDOT O2. Thanks to over 50 years of scientific research conducted by legendary coach Dr. Jack Daniels, runners and coaches can quickly determine appropriate training paces, equate race performances and adjust for heat and altitude. Features: • Calculate time, distance and race paces • Calculate your current training paces • Calculate and compare the equivalent performances of a race result at other distances • Calculate the effect of temperature or altitude on training and race paces What's Your VDOT? VDOT is a measure of your current running ability. It assigns a score to all running performances, let's you determine your current training paces, and equates a race time in one distance to another. For instance, you can compare your VDOT score from a recent 5k result to a friend's score who just ran a half marathon. Who won? What VDOT Level Have You Reached? Input a race result or estimated performance and learn what score it reaches on the VDOT scale. Enter all your past performances to see which race result scores the highest. There are 10 levels starting at Beginner - White (Female: 34.3, Male: 36.8) all the way up to Professional - Gold (Female: 71, Male: 80).

Verdict
The clearest difference is rating: VDOT Running Calculator at 4.9 against KMetrix's 4.0. VDOT Running Calculator also leads on ratings volume (1.6K vs 1). KMetrix's advantage is in-app purchases (none vs 2) and update cadence (monthly vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. VDOT Running Calculator sells 1 one-off in-app purchase. KMetrix asks for nothing beyond the download.
VDOT Running Calculator holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: VDOT Running Calculator has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of KMetrix's written reviews are positive against 74% of VDOT Running Calculator's, so the app with the better star average is not the one people write more warmly about.
KMetrix ships an update monthly, VDOT Running Calculator every 4 months. Both last shipped on November 1, 2026.
