The hairdresser “Bob the Barber” has a customer, Nick, who wants to schedule an appointment for a haircut. Bob places the details of the customer’s schedule in Fidelius calendar and here the magic starts: Fidelius sends automatic appointment reminders to Nick as requested by Bob’s preferences (e.g. as soon as the appointment is scheduled and the day before the appointment). Fidelius helps Bob’s business as it sends the messages automatically and assists Nick not to forget about his amazing haircut. In addition Nick can confirm the appointment or ask to reschedule directly from the reminder.
