PaceGrid vs Trace Run

Make your next run or ride easier to understand. PaceGrid brings GPS recording, routes, heart rate and training history together on iPhone and Apple Watch. RECORD YOUR WORKOUT Follow distance, pace, time and splits. Review your route and elevation afterwards, or record from Apple Watch without carrying your phone. CONNECT YOUR HEART RATE Pair a compatible Bluetooth heart-rate strap from the Record screen. PaceGrid uses fresh strap readings during recording and makes connection problems clear. Supported smart rings add heart-rate, sleep and recovery data. Device features vary by model. SEE THE BIGGER PICTURE Explore training load, heart-rate zones, workout trends and recovery estimates. These estimates help you interpret your history; they do not diagnose conditions or guarantee injury prevention. PLAN AND SHARE Save routes, use offline maps, export GPX files and optionally sync with Strava. Apple Health integration is optional. You choose which connected services receive your data.
