Health tracker guides

Find a comfortable tracker, compare your options and learn how Ray stays powered.

• Screenless fitness trackers: fewer distractions, more comfort

  Track your sleep and activity without another screen lighting up your wrist. A screenless fitness tracker keeps the details in an app and stays out of the way the rest of the day.

• Lightweight fitness trackers: a band you barely notice

  A lighter tracker can feel more comfortable when you run, dance or sleep. The best fit stays close to your skin without bouncing around or needing a tight strap.

• A fitness tracker without a charging cable

  Ray uses light to replenish its battery, so you have one less charger to remember. A short time in sunlight can replace a day’s energy use, while stored power carries it through darker days.

• Fitness trackers for small wrists: how to find a good fit

  For a small wrist, case size matters as much as strap size. Look for a short, low-profile device and a band that adjusts closely enough to stay comfortable.

• An Oura Ring alternative for people who prefer a wrist tracker

  Like the idea of discreet health tracking, but prefer to keep your fingers free? Ray offers sleep and activity tracking in a lightweight, screenless wrist band.

• Can indoor light charge Ray?

  Bright daylight beside a window can charge Ray. Ordinary room lighting is not enough. Outdoors, a short time in direct sunlight can replenish the energy used in a day.

• Health tracking without constant notifications

  You can keep track of your sleep and activity without adding another screen to your day. A screenless tracker records in the background, ready when you want to look.

• How to wear a fitness tracker with a mechanical watch

  Keep the watch you love and add a small tracker for sleep and activity. A screenless band can collect health data without putting a second watch face on your wrist.

• A fitness tracker for travel, without another cable

  Forgotten tracker chargers can leave gaps in your sleep and activity history. Ray uses light for power, with a battery reserve to carry it through days with less daylight.

• Smart ring vs fitness band: which fits your day?

  A smart ring keeps your wrists free. A fitness band keeps your fingers free. Start with what you would enjoy wearing, then compare the tracking features and charging routine.
