Built by a teen living with Type 1
A free app to make sense of Type 1.
And don’t do it alone.
BoostT1D is two things: an iPhone app that reads the CGM setup you already have, and a community of people who genuinely understand the day-to-day.

The iPhone app
Tools for everyday diabetes management
It reads the CGM setup you already have and helps you make sense of it, the patterns behind your week, and what to ask your care team about them.
Nutrition from a photo
Snap a photo of your meal and get nutrition back, carbs, protein, fat and calories.
A visual food log
Track meals, snacks and insulin in one place, so a day you want to understand is still there tomorrow.
Statistics & trends
Time-in-range statistics and pattern analysis that turn a month of readings into something you can act on.
The story so far
Built by a teen who lives with it
Aaron was diagnosed at 17 months old. BoostT1D started as the tool he wanted for himself, and it has since taken him to Capitol Hill and to the House of Code.

Just diagnosed
The first weeks are the hardest
If you or your child was just diagnosed, you don’t need another generic article. You need someone who understands the first days, weeks and months — and tools that make daily management clearer.
You’re not alone. We’ve got you.
What peer support looks like
1-on-1 conversations
Talk with Aaron or another peer who understands, honest support without judgment.
Real-life guidance
Lived experience for the first days, school, sleep, devices and travel. Not medical advice.
Someone to reach out to
Encouragement, or a reality check, on a tough day.
Practical resources
Guides for the first weeks, written by families and teens who live with T1D.
You at the centre, matched with people who are newly diagnosed, college students, parents of a child with T1D, athletes, gamers, and people 10+ years in.
Buddy network
Find your diabetes buddy
Connect with people who truly understand life with Type 1. We match you so you can support and learn from each other, based on three things:
- Shared interests
- Sport, gaming, study, something to talk about besides diabetes
- Life stage
- Teens, college students, and parents of a child with T1D
- Time since diagnosis
- Newly diagnosed, or ten years in
Start wherever you are today
Download the app and connect it to the CGM setup you already have, or skip the app entirely and just find someone who gets it. Both are free.
