BoostT1D

Life with Type 1 generates a lot of numbers and not much explanation. BoostT1D turns your own data into something you can actually read — and into better questions for the people who help you manage it.

Built by a teen living with Type 1 diabetes. Free, and you don't need an account.

CONNECTS TO THE SETUP YOU ALREADY HAVE
Bring in readings from Nightscout, Dexcom Share, or manually. Readings are stored on your device, so your history is there even when the connection isn't.

ESTIMATE CARBS FROM A PHOTO
Take a picture of your plate and get a carb estimate with the reasoning behind it, plus protein, fat, and fibre, a confidence level, and notes on what was assumed.
Every value is editable before you save. The estimate is a starting point, not the last word, and you record what you actually ate. Six free analyses a day.

SEE THE PATTERNS, NOT JUST THE NUMBERS
BoostT1D looks across your recent days for things worth noticing and explains what it found in plain language.
Every pattern shows how often it actually happened ("4 of 7 days"), what may have contributed, and questions worth raising with your care team. Nothing is asserted without the days behind it.

WALK INTO YOUR APPOINTMENT PREPARED
Turn weeks of data into a report you can hand over:
• What changed since last time — time in range, average glucose, variability, low episodes
• Recurrent high and low periods by time of day
• Day-by-day insulin, carbs, and time in range
• Weekday versus weekend comparison
• Your full therapy settings — basal, carb ratio, correction factor, targets
• Space for the questions you want answered, saved between visits
Export the whole thing as a PDF and email it ahead, or hand it over on the day.

ALSO IN THE APP
• Blood glucose history
• A weekly "What Happened?" review — summary, patterns, and a day-by-day breakdown
• Food log with your meal history and carb totals

WHAT BOOSTT1D IS NOT
BoostT1D is not a medical device. It does not provide medical advice, diagnosis, or treatment recommendations, and it does not tell you how much insulin to take.
It is an educational tool for understanding your own data and preparing for conversations with your healthcare team. Always consult your healthcare provider.

BUILT FROM LIVED EXPERIENCE
BoostT1D was created by a teen diagnosed with Type 1 at 17 months old, who wanted the app he couldn't find: one that answered "why did this happen?" instead of only recording that it did.

There's a community side too, at www.boostt1d.com — peer buddies, volunteers, and resources for anyone newly diagnosed.
