Fitness App in iPadOS 14.3 beta
Previously discovered in iPadOS 14.2 beta, Fitness App can only be launched via Handoff from Apple Watch.
Fitness App doesn’t seem to be present in the iPadOS 14.2 release version. It is now accessible as an app in iPadOS 14.3 beta. No contents or functionality as of now. Fitness App is part of Apple Fitness+ that would be launched in late 2020.
