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.

Just diagnosed, or supporting someone who was? Start here.

Two BoostT1D screens on iPhone. Snap a Meal: a photographed slice of pizza analysed into 380 calories, 12g fat, 2g fibre and 13g protein, with a note that the estimate assumes a standard slice. Doctor Visit: what changed since the last appointment — time in range up 3.5%, average glucose down 15 mg/dL.

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

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 BoostT1D dashboard on iPhone: a glucose reading of 182 mg/dL above range and steady, pulled from Nightscout, with active insulin and carbs, the last meal logged, and a glucose trend chart against the target range.

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.
