PowerWatch was born out of a mission to create the best active lifestyle smartwatch experience powered by the energy of the user. We’re working to build a world powered by you, where devices can remain always-on and untethered from wasteful chargers.

The series of smartwatches powered by only body-heat and solar power, are energized by MATRIX’s Gemini and Mercury modules, and a custom low-powered operating system designed specifically for PowerWatch. PowerWatch works with Apple HealthKit.

Awesome app and watch!

I have no complaints about this watch because the updates are making it better everytime. The sleep tracking works better now. The syncing is faster and more reliable.

I do wish however it had the option of displaying the seconds.... any chance of getting this in the next update? Pretty pretty please?? 🤗

New app is WAY better!!

Both the watch and app are a big improvement over the first version. Understandable PowerWatch would go through some growing pains, but this time they got it right! App looks really good and it’s intuitive to use. I still need time to record data over a longer period, but everything has been great thus far!
