Heart Rate Variability for Forerunner 55

Get the Premium HRV Features of high-end Garmin watches on your Forerunner 55 or 165 for free. Your watch has the hardware - we just unlock the sophisticated software that Garmin reserves for its pricier models. Track your recovery metrics: See how your Heart Rate and HRV change throughout the night and compare weekly trends against your established personal baseline. ____________________ Instructions for Use: You can record your HRV at any time, but for the best results and to track your progress throughout the week, it’s best to record at night. 1. When you go to sleep, open the app and press Start to begin recording your HRV. 2. When you wake up in the morning, press Start again to stop the recording. 3. The app will then display your stats. Over time, it learns from your data, adjusts your baseline, and graphs your weekly progress. ____________________ What is HRV? Heart Rate Variability (HRV) is the measurement of the tiny variations in time between your heartbeats. It is a key metric used by sports scientists to measure the balance between the two branches of your autonomic nervous system (stress vs. rest). What to aim for: The goal is not to have the highest HRV score, but rather to see a stable or gradually rising trend over several weeks, which indicates better overall health and resilience.

Version 2.0: Added a main menu allowing users to start a new recording or view past statistics.
