Summary
Tidepool Loop is the first fully interoperable automated insulin dosing app that originated as a patient-led initiative.
Background: A diabetes non-profit called Tidepool decided in 2018 to officially support Loop and shepherd it through the FDA process. Tidepool Loop was cleared by the FDA in January 2023 with plans to launch with Dexcom and other alternate controller-enabled (ACE) pump partners (RileyLink will no longer be necessary).
2023 Updates from Tidepool:
- Medtronic and Tidepool have decided to discontinue the development of a Medtronic insulin pump system compatible with Tidepool Loop.
- As Omnipod 5 is now commercially available, Insulet is devoting all available resources to their Omnipod products, including the global launch and further development of Omnipod 5.
- Future ACE Pumps that will be commercially compatible with Tidepool Loop will need to be FDA-cleared for use with third-party interoperable automated glycemic (iAGC) controllers.
The Simplera continuous glucose monitor (CGM) is Medtronic’s first disposable, all-in-one CGM. This sensor lasts for 7 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed.
FDA-approved for people with diabetes ages 2 years and older.
Components
Tidepool Loop : Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via insulin pump.
Simplera : Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5-minutes. Push-button applicator allows sensor to be placed on the body in one step.
Simplera : Receiver
Conveniently access glucose readings using a reader, smartphone, or directly on an Apple Watch. Phone app available for both iOS and Android devices.

Patient Considerations
Active Lifestyle
Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity.
Waterproof when submerged in water and must be within range of the feet of the receiver or mobile device.
Avoiding Highs and Lows
Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app.
Smaller size. The sensor is small and flat, and no overtape is required. Simplera’s adhesive is made from an anti-lint material that prevents sweat and water from reaching the sensor.
Easy Insulin Dosing
Customizable. Can bolus from phone or smartwatch and all settings are expected to be customizable. More information on modifications to insulin delivery will be available soon.
Real-time data and alerts make dose adjustment easier. The device can be integrated with the Medtronic InPen, which offers a bolus calculator based on carb ratios, meal estimations, the amount of insulin on board, and fixed dosing regimens
Easy to Use
Easy dosing. Software makes most dosing decisions easy to do on the fly.
No scanning is required. Readings are sent directly to the mobile app every 5 minutes.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
