For successful operation of the developed app, it must be regularly updated and maintained. This also applies to the monitoring and optimization of the server infrastructure. Typically, software companies offer this service. With APP3null, software maintenance and support is an optional part of the offer. All successful software needs further development and occasional updates since there is a need for new functions on the one hand and the source code has to be brought up to date on the other.
