Summary
Traditional syringe and needle. The most affordable insulin delivery option.
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.
Components
Syringe and Vial : Bolus Insulin
Bolus (fast-acting) insulin vial for meal time or high blood sugar correction.

Syringe and Vial : Needles
Classic syringes with plunger used to fill insulin for injection
Tidepool Loop : Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via insulin pump.

Patient Considerations
Active Lifestyle
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.
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.
Avoiding Highs and Lows
Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control.
Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.
Comfort
Many components. Must carry insulin vials and large syringes but nothing attached to the body.
Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app.
Easy Insulin Dosing
Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.
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.
Easy to Use
Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.
Easy dosing. Software makes most dosing decisions easy to do on the fly.
Fewer Fingersticks
Frequent finger-sticks are required.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.
Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available.
