(Pocket-lint) - Misfit has announced that its wearable fitness trackers are going to get upgrades for swim tracking, but owners will have to pay for the privilege. It is also launching the hardware as a new version called the Misfit Speedo Shine 2.

Unlike most fitness trackers, that add features with software updates for free, Misfit is charging $10 for owners of the Misfit Shine 2 and Ray to get the upgrade. It's essentially just a firmware update that uses the algorithm already in its Speedo Shine and now the new Speedo Shine 2 models.

The update comes to coincide with the 2016 Olympics in Rio when, presumably, viewers will get the swimming bug and could be in need of a tracker for the wet.

The Misfit Speedo Shine 2, at $120, will be able to track daily activity, swimming including lap counting, plus sleep. The unit also features a vibration motor and multi-coloured lights for alerts and reminders. There is also a count down swim timer that vibrates when the elapsed time has been reached. The button can double as a music remote, selfie trigger, presentation clicker and more when used with a connected smartphone.

The Misfit Speedo Shine 2 is available now for $120 and the update is out via in-app purchase for $10 for those owners of a Shine 2 or Ray.
