The Story Behind the Loop

This App Started With a Question

A T1D daughter asked her dad when she could use the app he was building for her. That question became LinkLoop.

"Dad, when can I use the app you made for me?"
— My daughter, Type 1 Diabetic since childhood

She has had Type 1 diabetes since she was young. I have spent years watching her navigate fingersticks, site changes, sensor warmups, and the exhausting mental load of T1D — the constant background calculation that never fully turns off. I wanted to at least make it lighter. Not just for her, but for everyone in her circle who worries when the number goes quiet.

I showed her the idea early on — just a concept, nothing built yet. She asked when she could use it. My first honest thought was that this might be impossible. I had never built a mobile app. I had never published anything to the App Store, set up a developer account, integrated a medical device API, stood up a backend database, or packaged an app bundle. I did not know where to start.

So I started anyway. One experiment after another, self-teaching every piece — React Native, Expo, Node.js, MongoDB, OAuth 2.0, the Dexcom API, App Store Connect, TestFlight. Each thing I did not know how to do, I figured out. That process is how LinkLoop got built.

The gap I kept running into was the circle problem. Her Dexcom app showed her numbers. Dexcom Follow let me see them. But there was no single place where everyone who mattered — family members, the people who check in at 2am — could see the same thing, get the same alerts, and stay in the same loop without requiring each person to create a Dexcom account or be technically savvy enough to set up Follow.

LinkLoop is the answer to that problem. One app, two roles. The Warrior connects their Dexcom and controls who sees their data. Their Care Circle joins with a private invite code and sees the same live readings — no Dexcom account required, no complicated setup. Everyone is in the loop, or no one is. The warrior decides.

The answer to her question is: soon. Spring 2026 for the App Store. TestFlight beta now. She gets to try the app her question helped complete.

14 Years in IT. One App I Actually Needed to Build.

I've spent over 14 years in enterprise IT — systems analyst and administrator roles at eBay, Siemens, and ServiceNow. Before that, over a decade in tech support. I'm comfortable building things that need to work reliably.

In 2024, I started VibeCMD LLC because I wanted to build something that mattered to me personally. LinkLoop is the first product — and the one closest to home. Every decision about what to include, what to cut, and what to ship first has come down to one question: does this actually help my daughter and families like ours?

Where We Are Going

Phase 1 — Now

TestFlight Beta

Internal TestFlight with a few T1D families. Real-world usage, real feedback. Dexcom and Nightscout integrations are working. v1.5.0 adds Apple Watch companion app with complications.

Phase 2 — Spring 2026

App Store Launch

Public iOS App Store release. Pending approval — fingers crossed for Spring 2026.

Phase 3 — Beyond

T1D Advocacy

Reach more T1D families. Connect with T1D advocacy organizations. Expand Care Circle to support multiple warriors. Just keep making it better.

This isn't a startup chasing funding or building toward an exit. It's an app I built for my daughter and every family going through the same thing. That's the whole point, and it doesn't change as we grow.
