TestFlight, 2024 to 2025

Brink Mind

Mental health tools ignored the body, so Brink Mind brought heart data into the room.

The problem

Mental health apps ignore the body. Heart rate and HRV carry signal a journal never captures.

What I built

Brink Mind linked to the Apple Watch, using biometrics and journal entries to provide safer, more grounded support. It was the end of 2024, still early enough that I was teaching myself SwiftUI, UI/UX, product design, and how to be a CEO at the same time.

Proof

Reached TestFlight with working voice, biometrics, and on-device inference.

What I learned

I loved every second of the steep learning curve. It gave me the technical foundation I needed once the work shifted toward agentic development.

Native iOS and watchOS engineering, and the judgment to keep sensitive data on-device.

It was my first real proof that I could learn the thing by building the thing.
