APP computes time plans, based on due dates, given estimations and other variables. A list of tasks and a list of employees can be defined. Tasks can be assigned to one or more employees. It is also possible to define a maximum percentage value an employee can/should work on a task. Predecessors, public holidays, leaves, weekly working hours and some more parameters can be specified and are considered in the calculation. Version 2.4 replaced the old binary file format. Additionally a complete code refactoring has been made.
