Taping a Fitbit Air to the back of the upper arm can keep it off your wrist, but the evidence for how well it works is one person’s week-long experiment—not a validation of accuracy or a Fitbit-approved way to wear it. In a September 25, 2026, account, Lifehacker Senior Health Editor Beth Skwarecki reports that a CGM overpatch held the tracker during a run and that its heart-rate readings compared well with other devices she used. She also had to start a later workout manually after the tracker missed her first jog.
Why are people taping Fitbits to their arms?
The appeal is straightforward: moving a tracker off the wrist can make it less noticeable or more comfortable for someone who does not want to wear it there. Skwarecki tried this with the screenless Fitbit Air, attaching it to the back of her upper arm with a CGM overpatch. It was not a Fitbit-branded arm strap.
During her week with the setup, she says she sometimes forgot the tracker was there and liked having it out of the way. That is a personal comfort report, not a guarantee that the patch will feel comfortable or suit every person’s skin.
Does taping a Fitbit to your arm actually work?
In Skwarecki’s account, the patch stayed in place through sweat during a run, and she says the heart-rate data matched well with other devices she used for comparison. Those observations are encouraging for her particular run and setup, but the account does not describe a controlled test, a sample size, or a standardized accuracy protocol. It cannot establish that an upper-arm Fitbit Air gives accurate readings for other people, activities, or conditions.

Workout detection was not flawless: the tracker did not automatically detect her first jog. She says she got a better result on a later run by starting the workout manually. If automatic detection matters to you, that distinction is worth considering; manually starting an exercise session is not the same as confirming that a taped placement will reliably detect workouts.
What Fitbit’s placement guidance says
Fitbit’s cited manuals describe wrist placement, not taping a tracker to the upper arm. The Fitbit Blaze User Manual says, “Because blood flow in your arm increases the farther up you go, moving the tracker up a couple inches can improve the heart rate signal.” In context, that is advice to move the tracker higher on the wrist during exercise—not approval or validation of upper-arm mounting.

The Fitbit Charge HR Product Manual says the device is most accurate on the wrist and notes that physiology, wear location, and movement can affect accuracy. The Fitbit Versa 3 User Manual also gives wrist-wear guidance and suggests trying a higher position on the wrist during exercise. These are model-specific instructions; they should not be read as identical guidance for every Fitbit.

The only adhesive method directly described in the account is a CGM overpatch. Skwarecki says it kept the tracker in place during her sweaty run. She also discusses kinesiology tape and athletic or medical tape as alternatives, but expresses concern that small pieces may peel with sweat and showering. The account does not compare these options in a controlled test, name a particular patch, or establish compatibility with every tracker or skin type.

- Kinesiology, athletic, or medical tape: Alternatives mentioned by the author, with a concern that smaller pieces may peel during sweat or showers. Their performance was not tested comparatively in the account.
Whichever adhesive you consider, the practical questions are whether it stays secure during your normal activity, how removal affects your skin and the tracker, and whether you are willing to replace it. One person’s experience cannot determine which tape will work best for you.

Getting the tracker out of the way comes with extra handling. Skwarecki says she waited to remove the patch until it was time to charge the Fitbit, and had to deal with adhesive residue on both her skin and the device. Replacing patches also adds a recurring accessory cost. The account does not give a patch brand or price, so the expense will depend on what you choose.
