The iLet App is part of the iLet Bionic Pancreas system, an automated insulin delivery system that reduces the need to make decisions about your diabetes management – because it makes the decisions for you. The iLet needs only one number – your weight. After startup, the iLet learns about YOU – your basal insulin needs, how to correct you to target, and how much insulin you need for your meals. The goal of the iLet is to reduce the burden of diabetes management. The iLet Bionic Pancreas is the only insulin delivery system that makes 100% of your dosing decisions – so you don’t have to. -No carb counting* Instead of carb counting everything on your plate, the iLet just needs an estimate of the carbs in your meal — Usual for me, More or Less. -No corrections The iLet makes the corrections for you. If you’re trending high, it will automatically give you more insulin to bring you back in range. If you’re trending low, it will reduce your current insulin dosage. -Dosing decisions made for you The “Bionic” part of the iLet that communicates with your CGM and makes all of the insulin dosing decisions—no carb counting, no correction factors, no adjustments. -No pre-set basal rate iLet learns your needs and automatically adjusts your basal rate on the go. -Simple setup No settings are required to be entered or adjusted—the iLet system only needs your weight to get started. -Small but mighty Small (1.9” x 3.6” x 0.6”), lightweight and easy to put in your pocket or clip to your clothing. -Talks to your CGM Your iLet device communicates directly with your Dexcom CGM or FreeStyle Libre 3 Plus sensor to know where your glucose is headed. -Water resistant If you drop your iLet in water—no problem! It’s protected in up to 12 feet of water for up to 30 minutes. -iLet App The iLet App displays data from your iLet home screen in real time so you can view your current glucose, trend, notifications, and other important information directly on your phone. It also supports data synchronization, reports and updates for your iLet and allows you to share your data with your healthcare provider. -Create your Bionic Circle With the Bionic Circle App, up to 10 friends and family can remotely monitor you to see CGM values, meal announcements, and insulin doses and to receive alerts (Urgent Low / Urgent / Low Soon / Low/High / No Data). Please note that any changes made to your iLet therapy settings should be done under the guidance and supervision of a qualified healthcare professional. Before making any adjustments, it is important to consult with your doctor to ensure that the changes are appropriate for your individual needs and health status. *User must be carb aware For safety information, visit www.betabionics.com/safety

For people with diabetes, the Eversense 365 Application is compatible with the Eversense 365 Continuous Glucose Monitoring (CGM) System available in the US – the first and only CGM device with a sensor that measures glucose for a 1-year period. The app runs on a compatible mobile device and receives and displays glucose data from the Eversense 365 Smart Transmitter. In addition to your current glucose values, the Eversense 365 App provides alerts for potential hypoglycemia and hyperglycemia events based on your individual settings. It also displays the rate and direction of glucose changes, and provides the ability to enter glucose-related events such as meals, insulin delivery, and exercise. The Eversense 365 App is also compatible with the Eversense NOW Remote Monitoring mobile app and the Apple Health app. The Eversense 365 App cannot provide glucose readings unless it is used in conjunction with the Eversense 365 CGM system, which includes the Eversense 365 Smart Transmitter and Eversense 365 Sensor. The Eversense 365 CGM System is a prescription device, and you should contact your health care provider for more information and whether the Eversense 365 System is right for you.
