Apple has opened up early Apple Watch access to more developers ahead of its April 24 launch, reports the Financial Times. The company had previously allowed select, high profile developers to visit its Cupertino campus and use working versions of the device, but within the last two weeks it has expanded the offer to ~20 devs per day.
The program is huge for developers, allowing them to test their apps on a working device, rather than the Mac-based simulator Apple released last year. It's also very secretive, as entrants are asked to sign strict non-disclosure agreements, and forced to work in conference rooms draped with curtains and guarded by Apple security.
