Look at your CGM data everywhere you Like to Look. GotCGM takes the continuous glucose monitor (CGM) data from Dexcom or Libre blood sugar sensors and routes it in real-time to the places you actually look - your Apple watch, Apple Health, the iPhone lock and home screens, the dynamic island while you're in other apps, and your car - so you can glance at your blood sugar and get on with your day. WHY PEOPLE USE IT * Apple Watch: See your current BG and trend at a glance. GotCGM uses a custom Contact Complication to share CGM data to your watch in real time. * Apple Health: Puts the data from your CGM into AHK so you can see trends against your other health data, share with clinics and your physician, and more. * iPhone at a glance: Lock-screen and home-screen widgets keep BG visible without opening the app. * Live Activities show in the Dynamic Island and on your iPhone lock screen, on your Apple Watch, and with CarPlay. * For other watches and also in the car: the Calendar Integration surfaces BG info as a calendar event * Simple setup: Use your Dexcom Share or LibreLinkUp credentials to start routing your CGM data immediately and in real time. SUPPORTED CGMs * Dexcom G6/G7 * Abbott Freestyle Libre 2/3(+) * Other CGMs that have been configured to write their data into Apple Health or can write into Nightscout. SAFETY WARNING Warning: Dosing decisions should not be made based on this device. The user should follow instructions on the CGM system. Caution: The device is not intended to replace self monitoring practices as advised by a physician. GotCGM has not been reviewed by the FDA or any other regulatory body.

Smart Bolus is a smart insulin bolus calculator designed for people with diabetes who use multiple daily injections (MDI) or insulin pumps. Calculate your meal-time insulin dose in seconds based on your personal parameters: • Carb Ratio — how many grams of carbs covered by one unit of insulin • Insulin Sensitivity Factor (ISF) — how much one unit lowers your blood glucose • Target Glucose — your desired blood glucose level Key Features • Time-based profiles — Set different ratios for different times of day (morning, afternoon, evening, night). The app automatically selects the correct segment based on your meal time. • Multiple profiles — Create separate profiles for each family member. Ideal for parents managing more than one child with diabetes. • Dual glucose units — Supports both mg/dL and mmol/L with automatic conversion. • Calculation breakdown — See the carb dose, correction dose, and total suggested dose clearly. • Insulin on board (IOB) — Record the dose you actually took and the app tracks how much is still active, subtracting it from your next suggestion to help avoid stacking. • Carbs on board (COB) — Insulin matched by unabsorbed carbs from earlier meals no longer reduces your new meal's dose. • Insulin types & adjustable duration — Choose your insulin by active ingredient (lispro, aspart, glulisine, Fiasp, Lyumjev) and fine-tune how long it works for you (5–7 hours). • History your way — Record doses explicitly with one tap, review the last 7 days, and delete a single record or all of them. • Privacy first — All data stays on your device. No accounts, no cloud, no tracking. How It Works 1. Create your profile with your insulin parameters 2. Set time segments for different periods of the day 3. Enter your carbs and current glucose level 4. Get your suggested bolus dose instantly Disclaimer: Smart Bolus is a calculation aid only. Always consult your diabetes care team before making treatment decisions.
