Tidepool Loop
V-Go Patch
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.
V-Go is a convenient credit card-size patch pump that adheres to the skin and can be worn for 24 hours. This system is designed to be used with fast-acting insulin for people with type 2 diabetes who require 20, 30, or 40 units of insulin per day. Users can administer two units of insulin with every press of a button on the device. This device is a hybrid between injections and an insulin pump to allow for discreet dosing without the need for programming or multiple injections.
FDA-approved for people 21 years of age and older with type 2 diabetes.

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.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly, but the device is water-resistant.
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.
Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Low-profile mobile app. Dosing and other adjustments can be done directly on the mobile app.
Free of tubing. Patches do not have tubing, but it must be worn in areas that are easy to reach for insulin dosing.
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.
Simple with few steps. 24-hour bolus range: up to 36 units per 24 hours, doses in 2-unit increments. Preset basal rate of 20, 30, or 40 units per 24 hours.
Easy to Use
Easy dosing. Software makes most dosing decisions easy to do on the fly.
Simple with few steps. Patch is replaced every 24-hours with insulin administered at the click of a button.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available.
Hideable. Bulkier patch pump, but not as noticeable as injections. Bolus button can be used discreetly through clothing.
