In a high-stakes environment like data centers, where uptime equals millions of dollars and human safety is critical, there's often a disconnect between human status and system status. We wanted to bridge that gap, uniting people, devices, and data into a single live ecosystem.

PulseLink does this. With support for iPhone, Apple Watch, iPad, Mac, and Vision Pro, it'll continuously share live vitals (heart rate, oxygen, and energy) from your Apple Watch or AirPod Pros Gen 3 across teams using Apple's secure MultipeerConnectivity network. But PulseLink goes far beyond health:

It has an integrated ticket management system, where you can log incidents, track maintenance and high/low priority tasks, all without switching tools.
It has a built-in Gemini-powered LLM that can answer complex hardware issues, suggest troubleshooting steps, and even guide you through emergencies.
From wrist to wall, every device in the Apple Ecosystem can display synchronized data for operational awareness.

As far as how we built it: -For watchOS, we stream real-time vitals using HealthKit and WatchConnectivity -iOS acts as the network hub, able to receive and broadcast vitals via MultipeerConnectivity. iOS also holds the ticketing system for Data Center Technicians, built on SwiftUI with a Gemini-powered LLM through API calls. -iPad/macOS act as a large-format dashboard displaying all active technicians and their metrics, still powered by the shared information with HealthKit and MultipeerConnectivity -Vision Pro holds the role that iPad/macOS hold, but in an immersive, spatial dashboard.

Challenges we faced:

Apart from having 24 hours to do this, the biggest probably was getting the HealthKit data to sync in real-time, as designing a low-latency peer network, even with Apple's frameworks, can be difficult at times.
Managing privacy and data security while transmitting health data.
Optimizing UI layouts for 5 Apple platforms with drastically different form factors
