Nrdevo apps
Nedevo provide two types of apps, one type was built at the system level, and another type was built at the application manager level. There is no difference except that it is not possible to build applications at the system level except from within the company and our own programmers duo to security matters, as apps built on the system can be available to all our subscribed users, while applications built at the application manager level must be installed through the store and get full review.
