Do you often use the Instagram on your Apple Watch? It must be a bad news that Instagram halts its Apple Watch app as of April 1st.
According to a French site iPhoneAddict, Instagram’s Watch app was developed via using using the watchOS 1 SDK, however, Apple just abandon it from April 1st, those apps which created with watchOS 1 SDK will no longer be supported on the Apple Watch devices. On the other hand, Instagram has no plan to rebuild the app with watchOS 2 SDK or late, so, this is the reason why Instagram stops its Apple Watch applications.
In addition to Instagram, there are already several apps quit abandon their apps in the device, and people have to use them with other devices if these apps are necessary for them.
