Inspire HR not tracking duration and distance correctly

[etgump]

Inspire HR is not tracking activity movement and distance correctly. HR will be as much as 3-4 minutes short in a 20 minute activity and as much as 3/10 mile short in 1.7 miles. I use a separate stopwatch for activity and a know distance for miles. How do I correct or adjust HR?

@etgump Welcome to the Community.

Let me help you with your Inspire HR not properly detecting your activity and duration. Your device detects activities based on the motion on your arm. The automatic detection is a feature called SmartTrack. For example when using the elliptical machine make sure you have the moving bars so your device detects the motion and records the activity itself, once an Elliptical activity is saved on your account it should show on the Recent Exercise area. If your heart rate is high but there isn't much motion (yoga, weight lifting, etc.) then these activities will be difficult to be detected by your device. Still you can manually log your activity so you have a record on your account or use the activity mode on the device itself.

Regarding the distance your device uses the number of steps and stride length to calculate the distance. You can improve the accuracy by measuring and logging your stride length. Feel free to use these instructions to do this.

Let me know how it goes.
