All your health data in one place: blood sugar, insulin, meals, activity and sleep. Everything synced automatically with Apple Health and your CGM. Understanding your blood sugar means keeping track of many factors every day. syncsulin brings them all together in one place. Clear, organized, and automatic. syncsulin is your personal blood sugar and lifestyle diary for everyday life. The app connects to Apple Health and your CGM sensor and shows your blood sugar readings, insulin, meals, activity, and sleep in a single, tidy overview, so you spend less time hunting for your data and more time understanding it. YOUR DATA, SYNCED AUTOMATICALLY - Apple Health integration: With your permission, syncsulin reads blood sugar readings, steps, heart rate, and sleep automatically in the background, no need to open the app. - CGM connection: Link your Dexcom sensor. More sensors are on the way. EVERYTHING AT A GLANCE - Dashboard: Your home screen shows you instantly how your day is going, with a clean blood sugar graph that adapts to your data. - Feed: A chronological timeline of all your entries: blood sugar readings, meals, insulin doses, activity and sleep, all in context. FAST MANUAL LOGGING Not everything comes from a sensor. In just a few taps, you can log: - Blood sugar: enter a reading manually at any time - Insulin: dose, type, and units - Meals and snacks - Cycle data: because the menstrual cycle can influence blood sugar patterns too COMING SOON We are constantly improving syncsulin. Upcoming versions will bring trend views and pattern insights: see how everyday factors — food, movement, sleep — are reflected in your blood sugar data.
