The Context
In June 2017, Apple announced GymKit at WWDC as part of watchOS 4: a protocol that allows Apple Watch to connect directly with compatible cardio equipment. When a user taps their watch to a GymKit-enabled machine, the two devices sync in real time, sharing workout data between the equipment and the watch. Heart rate, calories, distance, and duration all flow between the machine and the wearable without manual entry.
Apple launched GymKit with seven founding equipment partners, collectively representing approximately 80 percent of the global gym equipment market: Life Fitness, Cybex, Matrix, Technogym, Schwinn, Star Trac, and StairMaster. Three of those seven brands, Schwinn, Star Trac, and StairMaster, are part of the Core Health & Fitness portfolio.
For the feature to work visually, each partner brand needed its own approved logo asset displayed inside Apple’s Workout app at the moment of pairing. Apple reached out to Core Health & Fitness with the technical specifications before the public announcement. The work was done under NDA.
Those assets were built by Robert Pallister, founder of Fourside Studios, working as an embedded member of the Core Health & Fitness marketing team.
The Work
Apple’s specifications were precise. The deliverables were PNG files at exact pixel dimensions with strict file size limits, each featuring the brand logo placed on a solid background color matching the brand’s primary color. No creative interpretation. No deviation from spec.
Getting the assets approved and into the OS required:
- Building each logo mark to Apple’s exact pixel and file size requirements
- Matching background colors precisely to each brand’s official color
- Submitting to Apple for review and receiving approval before the assets could be accepted into watchOS
The approval gate was not a formality. Apple reviewed each submission before allowing it into the operating system. The assets had to be correct before they went in, because once they were in, they were in.
GymKit officially rolled out to the public with watchOS 4.1 in December 2017. The assets were built and approved before that date, during the pre-announcement period when the feature had not yet been made public.
Why It Matters
These are small files. The work to produce them was not complex. But three of the seven brands that launched inside Apple Watch on day one were Core Health & Fitness brands, and the assets that represented them were built here.
A user in a commercial gym taps their Apple Watch to a Star Trac Cardio Piece, a StairMaster stepper, or a Schwinn indoor cycle. The logo that appears on their wrist in that moment is the asset built here.
That is not a marketing campaign with a run date. It is infrastructure. It exists in the OS until Apple or the brand changes it. Most brand work has a shelf life. This one does not.
The Takeaway
Not every deliverable is large. Some of the most durable work is a PNG file built to spec, submitted for approval, and accepted into a platform used by millions of people. Three of the seven founding GymKit equipment partners were Core Health & Fitness brands. They were ready on launch day because someone understood the specs, built the assets correctly, and got them through Apple’s review process before GymKit was ever announced.
