WHOOP Strap Firmware Release Notes

At WHOOP, we strive to continuously improve our product.  We deliver these improvements as firmware updates at a regular cadence which, in addition to various minor bug fixes and improvements at each release, contain items in the section below.  The firmware updates are over Bluetooth initiated from the WHOOP App on your mobile phone and sent to your Strap.  There are two programs on the Strap that may receive firmware updates: the Bluetooth Firmware and the Strap Firmware.  To update to the latest firmware please follow the instructions here: https://support.whoop.com/hc/en-us/articles/360042528574-How-to-update-your-Strap-s-firmware.

Please note that we do a phased rollout of firmware updates which allows us to monitor the performance of new firmware on a smaller population of WHOOP Straps.  This allows us to make any necessary changes before all users receive an update.  If you see new release notes, but do not see a prompt to update your firmware, please be patient.  It may take 1-2 weeks before all users will receive the update.
