Trace
Read full descriptionHide full description
Deep analysis of your training and health data, a plan that fits around your everyday life, and an AI coach you can ask anything. What used to take several apps and a coach now sits in one app: trace. WHAT THE APP COMPUTES • Readiness: a score from 0 to 100 every morning from HRV, resting heart rate, sleep and your recent training load, each factor measured against your own values from the past weeks rather than population norms • Training load: fitness, fatigue and form (CTL, ATL, TSB), with a warning when your ramp gets too steep or your training too monotonous • Durability and aerobic efficiency: how well your power holds up when the ride gets long, and whether your heart rate is coming down at the same power • VO2max and fitness age, both tracked over months • Heat acclimatization, derived automatically from your normal sessions • Cycling: Critical Power and W' with no test protocol, plus power curve, W'bal and your rider type • Running: critical pace, heart rate recovery and training effect • Climbs: detected automatically, with vertical meters per hour and pacing, and every one of your ascents comparable BEYOND THE NUMBERS • Training plans that follow your goal, the time you have and what you can actually handle. When life gets in the way, the plan adapts instead of punishing you with a red deficit • Even without a plan trace suggests a session every day, and with a subscription you can also create your own from the workout catalog • One tap sends a planned session to your head unit or your watch, with the warm-up, the intervals and targets in watts or heart rate • After every session the workout report shows how well plan and execution lined up • Race preparation with course simulation, race prediction and pacing for your target event • Fueling plans with concrete carbohydrate and fluid amounts, for training and for race day • The trace Coach knows your data, your history and your goals, and answers any question about them HOW THE NUMBERS ARE MADE trace computes all of these values itself, with no language model involved. The AI explains them, answers questions and drafts your plans, and even there it stays inside the computed limits.

Verdict
The clearest difference is update cadence: iFocus Core at every 6 days against Trace's every 2 weeks. Trace's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
