See your core body temperature rise and change during intense workouts

Track Lactate Threshold and Core Body Temperature on the same watch screen  

Compare your Polar H10 EKG heart rate to your Wrist Photoplethysmogram heart rate

Follow your respiratory rate (derived from the QRS Height in your EKG) and compare to your heart rate over time  

Use watch-based GPS to observe speed -- no need to carry your phone.

Follow GPS Speed (V) and Heart Rate to determine V200 (@ HR=200 bpm)  

Synchronize your EKG to your motion cadence for diastolic stepping

Utilize more accurate Polar H10 Heart Rate frequency to synchronize your motion cadence frequency  

Average your EKG over 4 - 20 beats to visualize P, QRS, and T waves

Capture 8-second EKG strips, especially when there is both an R-R interval outlier and EKG Quality is good  

Observe RR intervals at different heart rate ranges to best determine RR interval outliers during exercise

Watch the EKG Fast Fourier Transform change dramatically during heavy exercise, especially at Lactate Threshold. 

All your saved charts are immediately available for viewing, during and right after an exercise session is completed

Upload your saved charts in seconds to your Google Drive, use Watch-based WiFi or LTE connections, no phone required. 

Use Pixel Watch Apps like AnExplorer to see your saved charts locally on the watch

Exercise Charts and Screenshots are saved to watch common directories for easy viewing.
