Yes. You can wear Ray on your ankle with a suitable band. This gives you another placement option if you prefer to keep your wrists free.
Which band should I use?
Ray accepts standard 8 mm bands, but the band also needs to be long enough for your ankle. Check its adjustment range against your ankle measurement; a band that fits your wrist may not fit your ankle.
Choose a comfortable fit that keeps the sensors against your skin without squeezing or sliding. See Ray band compatibility and sizing before choosing a band.
What about sunlight?
Socks and trouser legs can cover Ray's solar face. Give the panel suitable outdoor sunlight when charging, rather than counting time spent outside with it covered. Read the current charging guidance.
For Ray's current measurements and activity-tracking limits, see what Ray tracks.
What if I have a nickel allergy?
Ray's stainless-steel case contains nickel. Do not use Ray if you have a nickel allergy, regardless of the band or where you wear it.
