KLYS
More accurate than any watch. My recovery has never been this optimized.
KLYS
I love having all my data without the annoying notifications. It looks like a high-end ring but does so much more.
KLYS
Way better for lifting. It’s light, stays out of the way, and the 'Readiness' score is scary accurate. Best gym tech I’ve owned.
KLYS
The sleep data showed me exactly why I was always tired. Made a few changes and I feel 10x better. Battery actually lasts all week.
KLYS
I was skeptical about the price, but it’s honestly worth every penny. I forget it’s even on my finger. The sleep data is a total eye-opener.
KLYS
The real gem is the integrated smartphone app with guided classes and body tracking. I really like it.
KLYS
Hated the daily charging and the constant pings. This is so much more 'me'. Sleek, light, and the battery is a beast.
KLYS
Realized my 4 PM coffee was killing my deep sleep. The data doesn't lie. Been sleeping 10x better since I adjusted. Worth every penny
KLYS
The Readiness score is scary. It told me to rest today and I actually felt like trash. It knows my body better than I do!
We’d love to hear from you
