Insulin on Board: What IOB Means and How to Avoid Stacking
The most common way to end up low is a correction stacked on a dose that was still working. How IOB decays, why the curve is not a straight line, and when active insulin turns risky.
Track blood glucose, insulin, meals, and exercise — sync your CGM, count carbs, calculate boluses, and share with family. Everything you need in one app, built for people who actually live with diabetes.
One line, one band. Everything in SweetLife comes back to whether you're inside it.
Built by someone who gets it. Every feature exists because people with diabetes actually need it.
Log readings instantly, see trends with beautiful charts, and understand your patterns over time. Supports both mg/dL and mmol/L.
Connect your Medtronic pump and CGM to automatically import readings. No manual entry — your data flows in the background, every 5 minutes.
A built-in companion that understands diabetes. Ask about carb counts, talk through a rough day, or get pattern insights — anytime. (Chug is an AI assistant for education and support, not medical advice.)
Track bolus and basal doses, use the built-in calculator to estimate corrections, and log your insulin duration and carb ratios.
Track meals with carb counts using the built-in barcode scanner. Log exercise and see how activity affects your blood sugar in real time.
See your Time in Range, estimated A1C, GMI, standard deviation, and day-of-week patterns. Understand your data, not just your numbers.
Read blood glucose from Apple Health and write your logs back — keeping all your health data in one unified record.
Build daily logging habits with streaks, earn achievements, level up, and celebrate every win — big or small.

The most common way to end up low is a correction stacked on a dose that was still working. How IOB decays, why the curve is not a straight line, and when active insulin turns risky.
Rapid insulin needs 15 to 20 minutes to get going. Most carbohydrate hits the bloodstream in about 15. Dose at the first bite and you have already lost the race — here is how to win it back, and when not to try.
Your CGM says 7.2%. The lab says 8.0%. Neither is broken. GMI and A1C measure different things by different mechanisms, and the gap between them is itself useful information.
Compare the best bolus calculator apps for Type 1 diabetes. Learn how insulin calculators work, what features like IOB modeling actually matter, and which apps help you dose smarter.
An honest comparison of the two biggest CGM data platforms. Which one is better for tracking blood glucose, sharing with your doctor, and managing Type 1 diabetes?
