Fitbit users tape devices to arms for better heart rate tracking

Looking for ways to avoid wearing the latest Fitbit Air on their wrists, a number of inventive users have started adhering the tracker directly onto their arms using medical tapes. Since Google has not yet introduced any official bicep bands or alternative mounting solutions for this device, this creative workaround is gaining popularity. For those eager to keep their device away from their wrist, this method offers a more comfortable and discreet experience during both daily activities and workouts.

Users experiment with creative mounting solutions

Inspired by the flexibility offered by brands like Whoop—which markets bicep bands and clothing designed for tracker placement beyond the wrist—owners of the Fitbit Air—which is priced at $99.99—are sharing tips in forums on how to attach the screenless device elsewhere on their body using tape. This trend isn’t just about emulating competitors; it also helps users avoid the hassles wrist-based devices can cause, such as interfering with gym equipment like kettlebells or clashing with certain clothing. Many find that relocating the tracker to an arm or leg provides a more unobtrusive experience, one that’s easy to forget during daily wear.

Without official accessories from Google for alternate placement, such user-driven solutions are filling the gap for now.

Evaluating adhesive options and considerations

Several products have been put to the test as users attempt to keep their Fitbit Air attached securely all day. KT Tape, commonly used by athletes, is a frequent choice but may lose grip after intense exercise or exposure to water. Traditional athletic or medical tapes have also been tried; however, these often struggle to stick effectively when resized for a small device like the Fitbit Air.

For enhanced durability, overpatches designed for continuous glucose monitors (CGMs) have proven especially effective. Made for wear times of up to two weeks, CGM adhesives and their large sticker-style overpatches are built to remain secure through sweat and showers. They are well-suited for the Fitbit Air, whose battery typically lasts about a week, providing a secure attachment for the entire charge cycle.

Potential impact on tracking and drawbacks of off-label use

Experiences with the taped-on Fitbit Air indicate that heart rate monitoring remains accurate, particularly when the device is affixed to the back of the arm using a CGM overpatch. During running tests, heart rate data closely matched that from competing trackers. Some users have found that a snug fit and the absence of ambient light can even enhance sensor readings, though results vary with body type and exact placement.

Despite these benefits, several limitations arise. Because Fitbit’s sensors are optimized for wrist movement patterns, certain automated features—such as workout detection—might not be as effective when the tracker is worn on the upper arm or leg. Users may need to manually start and stop activity tracking. Furthermore, removing strong adhesives like CGM overpatches can be unpleasant, especially given the weekly removal required for recharging. Taking off the tape in a warm shower may help ease discomfort.

The ongoing purchase of overpatches for each week’s use could become costly for those considering this modification on a long-term basis. Nonetheless, for individuals wanting to avoid wristbands temporarily or during specific activities, this taping trend is growing—and it suggests that official accessories for alternative wear might have strong demand in the future.
