Which, if any, of these gadgets sound interesting to you:
- Glucometer
- CGM
- Fitbit
- Garmin watch
- Heart-Rate Variability (HRV) detector
Each of these gadgets measures either blood glucose, physical activity, or recovery such as sleep, resting heart rate, and heart-rate variability. I find this data important for understanding my metabolic health and recovery, and I make adjustments to diet and lifestyle every day based on this data.
You have probably noticed that my setup is not an Apple shop, so I have apps for all of these on my Android phone. If you have an Apple shop, then I understand there are Apple equivalents available for most if not all of these.
