Run Analytics vs PacerX

Understand the runs you already record. Run Analytics brings pace, splits, training load and fitness trends together so you can follow your progress over time. NEW: ANALYSE YOUR TRAINING WITH AI Choose what to review (today's workout, your latest session against the previous one, this week or this month against the last) and the app turns your data into a professional prompt, in your language. One tap copies it and opens your AI assistant: just paste it into a new chat. ANALYSIS, NOT ANOTHER RECORDER Import running workouts from Apple Health or connect Garmin. Run Analytics analyzes the training you already complete, so you can keep using your current watch and recording routine. UNDERSTAND EVERY RUN • Pace, distance, duration, heart rate and calories • Split-by-split analysis with route context when available • Critical Pace estimation and personalized running zones • Running Training Stress Score (rTSS) • Fitness, fatigue and form trends (CTL, ATL and TSB) • Personal bests and best efforts by distance • Weekly, monthly and yearly progress views • CSV and JSON export TRAIN WITH CONTEXT See whether pace is improving at a similar heart rate, how recent sessions affect fatigue, and how your current form compares with previous weeks. Metrics are estimates based on your imported workout data; they are not coaching or medical advice. PRIVACY BY DESIGN Core analysis stays on your device. Optional Garmin sync sends workouts, heart rate, routes and identifiers to our servers. In Data sources you can withdraw consent and request deletion of active server data; local workouts remain.

How fast could you race today? PacerX turns the runs already in Apple Health into personalized 5K, 10K, half marathon, and marathon predictions—then shows you the training evidence behind every estimate. Built for runners who want more than a workout list or a one-result pace calculator, PacerX looks across your recent training, best efforts, trends, pace, heart rate, effort, weather, elevation, and consistency to help you understand where your fitness is heading. SMARTER RACE PREDICTIONS See realistic estimates for 5K, 10K, Half Marathon, and Marathon based on your recent training. Open any prediction to understand the runs and signals that influenced it. PREDICTION HISTORY Track how your projected race fitness changes over time. See when your training is moving the needle—and when your estimates are holding steady. DEEP ANALYSIS On supported devices, Deep Analysis uses Apple Intelligence to give you a deeper explanation of what your recent training says about race readiness. PacerX uses on-device processing where appropriate and can use Apple Private Cloud Compute for supported Deep Analysis requests. COMPARE YOUR RUNS Open any run and compare it with a relevant past workout—or choose one yourself. Review pace and heart-rate charts, side-by-side metrics, and context such as route, distance, effort, weather, and elevation. FIND YOUR BEST RUNS Discover validated personal bests and standout efforts across your running history, including 1K, mile, 5K, 10K, half marathon, marathon, longest run, most climbing, most consistent splits, and more.

PRIVATE BY DESIGN PacerX reads your running data from Apple Health. No account is required, there are no ads, and your running history isn't used to build advertising profiles. Optional Deep Analysis may securely process derived training insights using Apple Private Cloud Compute, where request data is not stored. PacerX doesn't replace your coach or training plan. It gives you a clearer picture of what your training says—so your next conversation, workout, or race decision starts with better context. Understand your training. See what you're ready for. Keep moving forward.
