    WatchME and other HR/HRV monitoring apps

    I have been using a combination of apps for Pacing that utilise heart rate (HR) and heart rate variability (HRV) using Apple iWatch and iPhone. I have been using the watchME app and found it very useful, especially to monitor for conditions likely to induce PEM. Based on resting HR on waking...
