The Apollo device comes with a Medium Band, which we recommend for most adult and teen wrists and ankles.


We offer additional Bands for purchase if you would like multiple sizes. Since many people prefer to wear Apollo on the ankle while they sleep, order a size that can fit your ankle as well as your wrist. Size Small is best for children under age 12 and very small adult wrists. Size Large is best for larger adult ankles and upper arms.
