The Wahoo TRACKR is a rechargeable chest strap that broadcasts live heart-rate data to a compatible phone, watch, bike computer, or training app. It is a good fit if you want ANT+ and Bluetooth connectivity and already have a device to record your workouts. It is not a standalone tracker: TRACKR has no onboard workout storage, and Wahoo’s app and ELEMNT computers do not display or record its HRV data.
What the Wahoo TRACKR does—and who it suits
TRACKR is a chest-mounted ECG/EKG heart-rate monitor. It reads your heart rate and broadcasts it in real time to a paired receiver; the receiver, not the strap, records the activity. That makes it suited to runners and cyclists who want live heart-rate data on equipment or apps they already use, but not to someone who wants to leave a phone or watch behind and save a workout on the sensor.
Wahoo lists the strap at 39 g, with an adjustable length of 26.25–34.5 inches (66.7–87.6 cm) and fit for chests up to 50 inches (127 cm). Check your measurements before buying. Wahoo also sells a TRACKR replacement strap, including an XL option for chests over 50 inches; TICKR and TICKR X straps are not compatible, according to Wahoo’s TRACKR FAQ.
How TRACKR connects and what data it sends
The strap supports both ANT+ and Bluetooth, with up to three simultaneous Bluetooth connections, according to Wahoo’s undated product information and support FAQ. Wahoo lists compatibility with iOS and Android and says TRACKR can sync with Apple Watch, Strava, Peloton, adidas Running, Nike Run Club, and Wahoo products. Actual app support depends on the receiving product and its pairing options.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Apple Watch can use TRACKR as an external heart-rate monitor when the app supports it. Apple Watch does not then broadcast or export that heart-rate data to other apps or devices. If another device or app must record the workout, pair TRACKR separately to that receiver as well.
Wahoo’s app shows live BPM and includes average heart rate, maximum heart rate, and total calories in activity summaries. TRACKR also transmits BPM and HRV data once per second, including R-R interval values from the preceding second, when the receiver supports those metrics. Wahoo’s app and ELEMNT computers do not currently display or record HRV. TRACKR does not measure cadence or running dynamics such as vertical oscillation and ground contact time.

Battery, first use, and care
Wahoo describes battery life as over 100 active hours in normal conditions; its support FAQ says 110+ hours is possible in optimal conditions. These are manufacturer runtime claims, not an independently measured result. The lithium-ion battery is rechargeable but not user-replaceable. Charging uses the supplied USB-C-to-magnetic-interface cable. Wahoo says it cannot recommend charging cables that are not Wahoo- or Shokz-branded.

The sensor ships in low-power mode, so it may appear unresponsive until you connect it to its charging cable and a power source for the first time. For setup and wear, follow Wahoo’s TRACKR support guidance: position the strap directly against your skin, centered at the base of the sternum just below the pectoral muscles. Lightly moisten the inside contact pads, especially in cold or dry conditions, to help establish conductivity.

After exercise, remove the sensor pod before gently hand-washing the strap in warm water. Do not machine-wash it. Rinse between washes to remove salt deposits, and let the pod dry thoroughly before charging.
Water resistance is not swim tracking
Wahoo rates TRACKR IPX7 and says it can be submerged up to 1 meter for 30 minutes. That rating does not make it a supported swimming monitor: Bluetooth does not transmit underwater, and the sensor has no onboard storage to save a swim for later syncing. Use it for workouts where a compatible receiver can stay connected, rather than relying on it to record heart rate in the water.

How TRACKR compares with other monitor types
Wahoo positions TRACKR as its chest-strap option and TICKR FIT as an optical armband alternative. The choice is partly about fit and use: a chest strap sits against the torso and uses ECG sensing, while an optical armband reads from the arm. Neither form factor guarantees identical results for every wearer or activity, and Wahoo’s description of TRACKR as highly accurate is a manufacturer claim; the available source material does not establish an independent TRACKR accuracy figure.

|---|---|
| Fit and sensing | Chest strap and optical armband positions feel different; choose the form factor you are more likely to wear consistently. |
| Power | TRACKR is rechargeable and has a non-replaceable battery. A monitor with a replaceable cell may suit someone prioritizing easy battery replacement. |
| Connections | TRACKR supports ANT+ and Bluetooth, with up to three simultaneous Bluetooth connections. |
| Recording | TRACKR broadcasts live data but does not store workouts; the paired phone, watch, computer, or app must record. |
| Water use | IPX7 water resistance is distinct from underwater transmission or swim workout storage. |
| Extra metrics | HRV requires a receiver that supports it; Wahoo’s app and ELEMNT computers do not currently display or record it. TRACKR does not provide cadence or running dynamics. |

Is the Wahoo TRACKR worth it?
TRACKR is worth considering if you want a rechargeable chest strap that can send live heart rate to several compatible devices, and you already use a phone, watch, cycling computer, or app to capture workouts. Its mix of ANT+ and Bluetooth, plus support for up to three simultaneous Bluetooth connections, is useful when more than one receiver needs the signal.
Look elsewhere if you need offline workout storage, supported swim recording, user-replaceable battery, or HRV display in Wahoo’s app or ELEMNT computers. Wahoo states that TRACKR is not designed or intended to be used as a medical device.
