WatchKit was launched this evening by the Apple company together with iOS 8.2 with the idea of giving application developers the opportunity to create titles for the Apple Watch until its official launch on the market. According to the documentation provided by Apple for application developers, the Apple Watch will have to be permanently connected to an iPhone in order to be able to run applications, these using the hardware in the iPhone to be read and run, the information from them being only transferred to the Apple Watch screen using a Bluetooth connection.
Considering this construction, application developers are extremely limited in terms of developing applications, being forced to use only themes designed by Apple, which can be easily modified. Apple has said from the very beginning that an iPhone will compile the entire application for it to be displayed on the Apple Watch, so the watches will not be able to work by themselves under any condition because they do not have enough powerful hardware to run the specially designed applications for them. Apple Watch uses both the processor and the graphics card of an iPhone to run including notifications, the hardware of the terminals being necessary for any operation.
In order not to need a lot of processing power, Apple imposes certain templates that must be used for applications, these being also necessary for glances, they do not allow interaction with the user, even if they are displayed on the screen until closing. These glances can be used to redirect the user to an application or its menu, but beyond that the functionality is limited. Regarding notifications, developers can only modify the background of a notification, their templates being pre-set by Apple, developers not having much to do to make their applications compatible with them.
Although the Apple Watch will be extremely limited in terms of the possibility of developing applications now, Apple promises that towards the end of 2015 and probably after the release of iOS 9 it will allow the customization of applications to the liking of developers, so they will have to be patient.
