Built an iPhone + Apple Watch app that tells you what your body is trying to say

I've been working on an app called Auralis over the past few months.

The idea started because I realized my Apple Watch collects a ton of health data, but I never actually understood what any of it meant. Heart rate, HRV, respiratory rate, sleep stages, resting HR... it all felt like disconnected numbers.

So I built an app that tries to answer the question:

Some of the things it does:

• Turns sleep data into a Sleep Score with explanations.
• Calculates an Energy/Readiness Score using multiple HealthKit metrics.
• Explains HRV, resting heart rate, respiratory rate, and other health metrics in plain English.
• Syncs with Apple Watch and uses HealthKit data.
• Shows trends instead of just raw numbers.

The fun part wasn't the UI—it was figuring out how to combine all these different health signals into something that actually feels useful.

The project is built with:

• SwiftUI
• HealthKit
• WatchConnectivity
• Apple Watch integration
• Django backend for analytics and future AI features

This has probably been the biggest solo project I've built so far, and it's taught me way more than any tutorial ever could.

I'd genuinely love feedback from other builders:

• What would you add?
• What health insights do you wish your Apple Watch gave you?
• Any features you'd find genuinely useful?

Not trying to spam—I'm mostly interested in hearing what fellow builders think and what you'd improve.
