Scheduling App Design

We want the web app to be an extension of the web app/companion app for the real estate appraisers who work out in the field inspecting properties. Basically be so intuitive that they would never actually have to log into the web app to give updates to the main office. They can see their jobs, see their calendar in a simplified and a more detailed calendar(schedule) view, a to do list of jobs that are new, overdue, need an appointment or custom to dos, a generic & searchable/filterable list of all their current and past jobs, notes/messages, contacts and more (see the workflow attached). Our first iteration is an iOS app, with plans to release an iPad version shortly after.
