Read full description

Free, no account, no ads. Point the camera at a plate, and BoostT1D estimates the carbs. Pulls readings from Dexcom Share, LibreLinkUp or Nightscout. Built by a 17-year-old who has had Type 1 since he was 17 months old. CONNECTS TO THE SETUP YOU ALREADY HAVE Bring in readings from Nightscout, Dexcom Share, LibreLinkUp, 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 fiber, a confidence level, and notes on what was assumed. You can edit every value before you save. The estimate is a starting point, not the last word, and you record what you actually ate. 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 to help you understand your data and prepare 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. Congressional App Challenge National Winner. MIT Solve — AI for a Better World Grand Prize Winner. There's a community side too, at www.boostt1d.com — peer buddies, volunteers, and resources for anyone newly diagnosed.

FlashSnack does exactly one thing: given a photo or description of a meal or snack, logs it and saves it to Apple Health Kit. Use whatever you want to analyze your health, but don't waste time with slower food loggers that want to run the show. Log your meals in a flash! Free trial, then a low-cost monthly or annual subscription is required for continued use. Note: FlashSnack does not provide medical advice and the nutrition estimates must not be relied upon for medical decision-making. Always follow the advice of your physician or other licensed health care professionals.
