Track your steps, heart rate and sleep on one bright color screen, without a bulky watch on your wrist. A slim silicone band with a metal buckle works from the morning run to the last sleep cycle.
Track heart rate, sleep, steps and workouts in one stylish smart bracelet
- losing track of daily steps and activity
- no visibility into heart rate during workouts
- poor sleep awareness
- wanting fitness data without a bulky device
Track your heart, sleep and steps without the bulk
Stop guessing how your runs and nights are going. One slim band shows your heart rate, steps and sleep on a color screen you can glance at mid-stride.
Everything your wrist should be measuring
Heart rate you can check mid-run
The heart rate sensor sits behind the band and the color display puts the bpm reading right where you look. Check it between intervals, ease off when the number climbs too fast, and see how your effort shifts from one run to the next.
Sleep and steps, tracked together
The step counter and calorie tracking run through the day, then sleep tracking picks up at night. Both sit in one menu, so the morning check is a single glance rather than three apps and a phone unlock.
Wear it like jewelry, not a gadget
The silicone strap is light enough to forget about, and the metal buckle gives it a finished edge that plastic clasps lack. Pick jet black, silver or blush pink and it sits comfortably under a sleeve or next to a watch you already own.

Questions and answers
A wrist sensor reads well at steady effort and shows trends clearly. It will not match a chest strap during intervals or hard sprints. Use it to see whether your heart rate climbs and settles across weeks, not to set exact training zones. Sleep scores work the same way: a week of nights shows your pattern better than any single one.
The core features run from the bracelet itself. Steps, heart rate, calories, distance and sleep are all readable on the screen, and you switch sports modes with the buttons. If you plan to sync to a phone, confirm the pairing details in the product listing before you buy.
Silicone is easy to rinse after a sweaty session, and the metal buckle holds the fit without the wobble of a plastic clasp. Wipe it down after salty workouts and let it dry flat. Check the strap fit after the first few days, since a new band can feel stiff until it settles.
Yes. The dial menu lets you choose from the available face options. Running mode keeps steps, distance, calories and bpm on the screen during a session, so you do not have to dig through menus mid-run.
Yes. The big color screen and simple buttons do the work, so there is no training plan to set up first. Start by wearing it all day and reading your step count. Once you have a week of numbers, the morning runs and gym sessions start to make sense.
You get heart rate, sleep, steps, calorie and distance tracking in a band that looks like jewelry, for less than a full sports watch costs. If you mainly want to see how active your days are and how your runs are going, you pay for the features you will use and skip the rest.
