Morpheus

Dan Cullum · Apr 29, 2024 ·

I’ve been using a new fitness tracker called Morpheus for the past two weeks, and despite it being early days, I’m close to calling it the best fitness tracker I’ve used to date.

Morpheus is a heart rate monitor that is used for (a) a daily “recovery check”, and (b) tracking exercise.

Each morning when I wake up, I answer four simple questions: (1) how much did I sleep (which imports automatically from my Garmin watch), (2) how did I sleep, (3) how do I feel, and (4) how sore am I today. I then do a 2:30 minute Heart Rate Variability (HRV) measurement. The questions and HRV measurement are then used to calculate a ‘Recovery Score’. The score is a guide for how much I can push my training on a given day. A score above 80%, and I can push hard. Anything between 40-80%, I need to be careful. And below 40%, I should make it a rest day.

When I track my training sessions—both cardio and strength—my Recovery Score updates to reflect additional strain on my body. And Morpheus also updates the target time I should spend in my recovery, conditioning, and overload cardio zones each week.

I love the simplicity of the four questions each day, using recovery to adapt my level of exertion, and having clear time-based targets for training each week. I also really like how Morpheus is a pay-once product; no annoying monthly subscriptions like Whoop.

The UI and UX could still use some work. There are a bunch of kinks that haven’t been ironed out yet, but the core functionality is solid and useful.
