LEI has its own very capable scheduler, but I gather you want to use a tool that can manage the schedule for several disparate jobs. I am not familiar with Appworx and I'm not sure it will get you to your end goal. LEI, whether running as a seperate process or as a Domino server task, executes various EXEs for the different types of jobs and these EXEs call various DLLs for additional functionality.
