Scheduling appointments involves two parties:
- Host – a user who has created a WhenWorks account for Guests to view their availability and book appointments with them online. The Host must install the WhenWorks app on an iOS device running iOS 11 or greater.
- Guest – a user who visits the WhenWorks website to book appointments with a Host. Guests do not need to run the WhenWorks app. All a Guest needs is a web browser.
