Real customers from around the world read the actual stories they shared about how Apple Watch has changed their lives for the better.

With features like activity tracking, Time to Stand reminders, heart rate monitoring, and Emergency SOS, Apple Watch is a powerful health and fitness device.

Since the introduction of Apple Watch, people have been reaching out to Apple to describe how wearing it has helped them stay active, motivated, and more healthy.

In many cases they write to CEO Tim Cook directly — hence the “Dear Tim” and “Hello, Mr. Cook” mentions in the film.

It was important to us for “Dear Apple” to be absolutely authentic and truthful, so we decided to cast only real customers sharing their actual Apple Watch stories, and to use their own words when doing so.

Utilizing numerous internal Apple resources, we conducted an extensive search for letters, emails, and social posts written by Apple Watch owners around the world.

After identifying an initial pool of possibilities, we conducted a lengthy vetting process — which included email exchanges and FaceTime interviews — to finalize our cast, which reflected a wide range of ages, nationalities, and types of experiences with the product.
