I was 13 years old when I was diagnosed with Type 1 Diabetes in 2020. I remember feeling so overwhelmed when I was newly diagnosed and wanted to create an app with just the essentials you need from day 1 of diagnosis. My aim is to make it simple, reliable, and accessible to all… for free! Hope this app makes your life just a little easier. Disclaimer: T1D1 is an FDA-cleared, Class II medical device for over-the-counter use. Before use, a healthcare professional must provide your target blood glucose values, insulin-to-carbohydrate ratios, and correction factor (aka insulin sensitivity factor) to be programmed into the app. While the app is designed to support insulin dosing for individuals with Type 1 Diabetes Mellitus (T1DM) from age 2 and older, for children under 13, a parent or legal guardian must create and manage the account on the child’s behalf. Legal Manufacturer: Comerge AG Bubenbergestrasse 1 Zurich, 8045 Switzerland
