Olympic Pedigree V.O2 was built from the foundation of a scientifically-validated training methodology. 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

Most pace calculators assume you’ll run the same pace for the entire race. Real races rarely work that way. True Pace helps you build a race plan with paces that can vary by mile or kilometer, so you can see how hills, fueling, fatigue, strategy, and late-race surges affect your finish time. With True Pace 4.5, race planning can also include the course itself. Choose from an included library of selected major race courses, see the course outline and elevation profile, and build a Course-aware pacing plan that adjusts your target splits for climbs and descents. For your own races, you can attach a GPX file to add a course outline, elevation details, and, when usable elevation data is available, Course-aware pacing. With True Pace you can: • Plan even, positive, negative, step-based, or Course-aware pacing strategies • Choose an included race course and start planning faster • Import GPX files for custom race courses • See course outlines, elevation profiles, total gain/loss, and per-split elevation • Adjust individual miles or kilometers • Send your race or training-run pace targets to the Workout app on Apple Watch • Compare different race plans without starting over • Account for hills, water stops, fueling, and key course landmarks • See your pacing plan visually with an interactive Paceline graph • Add notes to any split • Export or print race plans as PDFs • Share saved races with friends, coaches, or other True Pace users • Plan common race distances including 5K, 10K, 10 mile, half marathon, marathon, and custom distances Course-Aware Pacing Course-aware pacing starts with your flat-equivalent pace, then adjusts your split targets based on the course profile. Use it to understand where a hilly course may naturally slow you down, where descents may help, and how those changes affect your estimated finish time. Course Profiles Included race courses can show the shape of the course, elevation gain and loss, and elevation details for each split. If you are planning a local race, trail race, or any event that is not in the included library, you can attach a GPX file from Files. Pacing Strategies True Pace makes it easy to test different ways to run the same race. Want to know what happens if you run steady through mile 20, then pick up the pace for the final 10K? Want to compare that against starting more conservatively and getting faster every few miles? True Pace lets you build, duplicate, and adjust those plans with very little data entry. Paceline The Paceline graph gives you a quick visual view of how your pace changes over the course of the race. For races with course data, you can also show elevation on the graph, then swipe across it to inspect individual splits and understand exactly where your plan gets faster, slower, climbs, or descends. Race Notes Add notes to any mile or kilometer so your plan includes more than numbers. Mark climbs, turns, water stops, gels, landmarks, or reminders for the moments you know will matter. Sharing and Printing Saved races can be shared with other True Pace users, sent to friends or coaches, exported as PDFs, or printed for race day. True Pace was built by an independent runner who wanted a better way to plan races than spreadsheets and generic calculators. You can use the app for free, with a one-time purchase available if you want to save unlimited races.

Verdict
The clearest difference is rating: V.O2 at 4.9 against True Pace's 4.3. V.O2 also leads on ratings volume (6.3K vs 3) and update cadence (weekly vs every 3 weeks). True Pace's advantage is review sentiment (100% vs 71%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. V.O2 sells 10 in-app purchases, starting at $12.99 per month and True 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 4.3. That said, the two scores are not equally well evidenced: V.O2 has 6.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 71% of V.O2's written reviews are positive against 100% of True 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, True Pace every 3 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
