The Story Behind SubQsync
Imagined and Built by a Parkinson's Patient
SubQsync was created from personal experience to simplify the daily challenges of managing continuous subcutaneous infusion therapies.
Why I Built SubQsync
Hi! My name is Tim Miller. I am a Young Onset Parkinson’s Disease patient who has been living with Parkinson’s for more than ten years.
Like many people living with chronic conditions, I am constantly looking for ways to make treatment more manageable and reduce the daily burden that comes with it. In April 2025, I began treatment with continuous subcutaneous infusion therapy using Vyalev® (foscarbidopa/ foslevodopa) from AbbVie. The results were remarkable and, in many ways, life-changing!
However, I quickly discovered that managing the therapy itself could be quite challenging. Keeping track of infusion sessions, monitoring supply levels, remembering cannula rotation schedules, coordinating treatment routines around work and family life, and organizing information for healthcare providers all added complexity to an already demanding daily routine. After all, living with Parkinson's Disease (and now having to be attached to a 24/7 infusion device) was difficult enough...there had to be a way to make this easier!
That experience became the inspiration for SubQsync.
The Challenges
Continuous infusion therapy offers tremendous benefits, but managing the workflow can be difficult—especially when the very condition being treated may affect focus, memory, planning, organization, and task completion.
I found myself relying on notes, reminders, memory, and multiple disconnected tools to manage therapy-related tasks. Over time, it became clear that a single, organized companion app could make the process simpler, more structured, and less stressful.
SubQsync was created to help users:
-
Track active infusion sessions and projected end times
-
Manage therapy supplies and inventory levels
-
Record symptoms and observations
-
Maintain infusion site rotation history
-
Keep important treatment information organized in one place
The Vision
SubQsync version 1.0 is only the beginning.
Future versions are planned to include features such as:
-
Customizable reminders and notifications
-
Infusion site rotation guidance
-
Smartphone widgets
-
Physician-friendly reports and summaries
-
Expanded support for additional continuous infusion therapies
While the first version was inspired by Parkinson’s disease treatment, the long-term vision is to support individuals using a wide variety of subcutaneous infusion therapies, including therapies used for diabetes, immunodeficiency disorders, chronic pain, hypertension, iron overload conditions, and others.
My goal is to create a flexible platform that helps patients spend less time managing treatment logistics and more time actually enjoying their lives.
A Personal Note
Building SubQsync has been one of the most rewarding challenges I have ever undertaken. As someone with no formal software development background, I spent countless evenings and more than 200 hours learning, designing, testing, and building the application with the help of modern development applications and AI tools.
Parkinson’s disease has changed many aspects of my life and has unfortunately forced me to let go of some of the dreams that I once had for my future. However, SubQsync became one dream that I was absolutely determined to see through.
I'm proud of what has been accomplished so far, but I'm even more excited about where it can go from here.
My hope is that SubQsync helps make therapy management a little easier, a little more organized, and a little less overwhelming for people who administer and rely upon these treatments every day.
Thank you for visiting, and thank you for joining me on this journey.
Sincerely,
Tim Miller
