TRAKR PRO Trakr Pro is an optional subscription. It adds deeper analysis and changes nothing about the tracking above: • Advanced Analytics — observations drawn from your own history: the weekdays you run most often, whether your pace is trending faster or slower, and the time of day you run strongest • Running DNA — a six-point profile of your last 90 days, scoring consistency, speed, endurance and recovery, and showing how your running divides between road and trail • Heart Rate Zones — how your time divided across five effort zones. Requires compatible heart-rate data already recorded in Apple Health, from a watch or chest strap • Personal Bests — your fastest 5K, 10K, half and full marathon, taken from inside your runs • Activity Heatmap — every run you have done, at a glance Trakr is built for running. Not steps, not the gym. Running. SUBSCRIPTION DETAILS Trakr Pro is an auto-renewing subscription, offered weekly or yearly. Payment is charged to your Apple Account at confirmation of purchase.
