The Procedure
  1. Aligning the WHOOP 4.0 to 5.0/MG band adapter horizontally with the clasp slot

    Align the WHOOP 4.0 Adapter on the 5.0/MG Track

    Center the adapter with the band and hold it horizontally. It should be level and aligned with the slot, not tilted. Take a moment to check alignment before applying pressure.

  2. Clicking the WHOOP 4.0 to 5.0/MG band adapter into place

    Click In the WHOOP 4.0 Band Adapter

    Apply firm, even pressure until you hear it click into place.

  3. WHOOP 4.0 band attached to the adapter, ready to clip onto a 5.0/MG sensor

    Snap your band onto the adapter

    Press your WHOOP 4.0 band into the adapter slot until it clicks. The same retention catches that locked it to the 4.0 sensor work on the adapter. Your old band is now wearing the new sensor.

Questions

Frequently asked questions

01Do WHOOP 4.0 bands fit the WHOOP 5.0 or MG?
Not natively — the clasp geometry differs between generations. The Whoopal adapter bridges the gap and lets your existing WHOOP 4.0 bands snap onto the 5.0/MG body.
02How long does the install take?
Under 30 seconds. No tools required. Align the adapter horizontally with the clasp slot, then apply firm downward pressure until you hear it click into place.
03What if the adapter doesn't click in?
Verify you're using a WHOOP 4.0 band (5.0/MG bands don't need an adapter). Slightly adjust the angle and try again with firm pressure from the hinge end first.
04Can I use the adapter in the pool or shower?
Yes. The Whoopal adapter is waterproof and rated for swimming and showering. It won't swell, corrode, or loosen when wet — the click-fit rail holds regardless of moisture.
05Will the adapter affect my WHOOP heart rate or sensor accuracy?
No. The adapter attaches only to the band clasp, not the sensor pod. Your WHOOP's heart rate, SpO2, and HRV readings are completely unaffected.
06Is the adapter compatible with WHOOP MG?
Yes — the adapter is designed for both WHOOP 5.0 and WHOOP MG. The clasp geometry is identical across both devices, so one adapter works for either.
07Will installing the adapter damage my WHOOP or void my warranty?
No. The adapter clips onto the band slot with no adhesive, no screws, and no permanent modification to your WHOOP device or band. It's fully reversible — remove it the same way it went on.
08Can I switch band styles after installing the adapter?
Yes. The adapter releases by reversing the install motion — lift the hinge end and slide it off. You can swap between band styles as often as you like.
