WHOOP 4.0 Firmware Release Notes

At WHOOP, we strive to continuously improve our product. We deliver these improvements via regular firmware updates. Each release contains various minor bug fixes and improvements, detailed in the release notes below. You can update your firmware via the WHOOP app by following the instructions in this guide.

Release notes for both the device's core firmware and Bluetooth firmware are listed below.

Note: We release firmware updates in phases which allows us to monitor the performance of new releases. This allows us to make any necessary changes before all members receive an update. If you see new release notes, but do not see a prompt to update your firmware, please be patient and check your app for an available update at a later time. It may take 1-2 weeks before all of our members receive the update.
