Using your heart rate, the WellBe bracelet “uses a patent pending algorithm to determine your stress and calmness levels based on time, location and people you meet throughout your day. Crafted from cork, the WellBe bracelet is lightweight, durable, and soft against your skin.”
Available through Indiegogo for $119 (or $129 for all 3 color straps), and an option to add-on a 21-day audio course in meditation for $39.
The app not only tracks and provides feedback, but also provides stress-reducing practices to help return to a calmer mental state (as measured by your heart rate). Your preferred practices can be saved in a playlist and you can set-up notifications to alert you when your stress-level exceeds a chosen level for immediate self-care and stress relief.
Enjoy your health!
