Pokemon Home is now available to download on Nintendo Switch. The cloud-based subscription service, which allows you to transfer Pokemon from previous games into Pokemon Sword and Shield among other features, was previously announced for a February 2020 release window, but the specific date was not confirmed.
There are two versions of Pokemon Home: the Nintendo Switch app and the mobile app. Currently, it seems that only the Nintendo Switch version is available for download. The mobile version has distinct features, including trading, and is a companion app to the Switch one rather than an alternative.
