In a report from The Verge, they have heard that there are certain software aspects of the smartwatch that won’t be ready at launch. Fitbit had previously said that they plan to have their own app store for their smartwatch, but the report claims that the app store might not be ready in time, and that the smartwatch will launch without any third-party apps.
Instead Fitbit will apparently be responsible for creating all the apps that will be available for the smartwatch, although they are also trying to court app developers to build apps for them. We suppose at the very least users will end up using the Fitbit smartwatch like a regular tracker, at least until the app store is up and running, which isn’t necessarily a bad thing.
However if you are looking forward to the smartwatch, it has recently been reported that the release has been delayed to the fall of 2017, which has also been independently confirmed by The Verge.
