Planner Studio Pro is multi-platform calendar-management app which allows you to manage multiple calendars at once by dividing them per user, keeping everything under control. You can connect more Planner Studio workstations on the same database so you can share calendars with other users of other workstations.
Planner Studio is really very flexible and can be applied to an infinite number of types of work, adaptable to every need.
