Hasbro has left many fans who purchased the Force Link 2.0 Starter Set, which includes the Force Link 2.0 arm wrist band, disappointed because it only works properly in combination with an app. This app however is not available for download in Apple's app store.
Hasbro has updated their app page to let Force Link 2.0 users who have iPhones know that the app will finally be available on or before May 1st, 2018. Android users can already use it, but again only with limited functionality.
From Hasbro's website: "We’re working hard to fix this so that you have the best experience possible. Thanks for your patience."
We'll be updating our figure database entries once the Force Link wrist band will work properly.
