Testflightapp.com is scheduled to shutdown its operation on its website by Feb 26, 2015. Apple has decided to shutdown the testflightapp.com to boost the usage of its testing service launched with iTunes connect. But there are not much evidences for this statement. Most of the forums and Tech news websites has started to let this word out. But eventually every one must start migrating to apple beta testing platform. The new service includes dashboard for developers and testers on the apple's beta service.
Testflightapp users must port their apps manually to the new beta service.
