Summary
Loop is a DIY (do-it-yourself) system. It takes some work to set up but allows people to think about diabetes less by automating basal insulin delivery based on predicted glucose levels. This system can be used with the Dexcom G6 and the Omnipod or Medtronic pumps. Information about DIY Loop can be found on the Loop or Riley Link websites.
NovoPen 6 & NovoPen Echo Plus provides the smart addition of a personal injection log. Both pens are compatible with Novo Nordisk insulins in Penfill 3 ml cartridges and work with NovoFine single-use disposable needles. You can transfer your insulin dosing information from your smart pen to your device using the app.
Components
Loop : Pump
The system is compatible with Omnipod (left) or Medtronic (right) pumps. Both options can be applied anywhere on the body that is comfortable.
Loop : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
DIY Loop : Transmitter
RileyLink allows the pump and sensor to communicate. It is only required if a Medtronic pump is used.
Loop : Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via an Omnipod or Medtronic pump.
NovoPen 6/NovoPen Echo : 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.
NovoPen 6/NovoPen Echo : Controller
Smart pen records daily injections and sends them to the compatible app by tapping the device with a compatible smartphone.
NovoPen 6/NovoPen Echo : Receiver
Smart pen and sensor readings displays dosage information directly on smart mobile device.
Device Details
Overview
This is a DIY (do-it-yourself) system that needs significant setup. It has the most flexibility in settings and device options. It also depends on a third device called a "Riley Link" to communicate between sensor, phone, and pump.
Discreet and modern option for people using multiple daily injections.
Affordability and Access
$$$$
Supplies can be covered for Omnipod or Medtronic pumps and Dexcom. Price range; $0-$8,574 to start and 0-$300/month. iPhone, app, and Riley link are not covered and must be set up independently. Riley link price range; $135-$165.
$$$$
Sometimes covered. NovoPens are covered by some commercial insurance companies; typically, users pay $21 out-of-pocket copays for the eight-month device. Prices range from $0- $78. For those without any insurance coverage, a single pen price is $78.
Data Monitoring Options
Yes
Compatible with Tidepool - a web-based diabetes data management system.
Yes
Hold the dose memory of the pen straight against the Near Field Communication (NFC) spot on your device. Wait while your injection details are automatically transferred to a compatible app on your device. Compatible with multiple data monitoring platforms, including Glooko, MySugr, and Dose Check.
Data View Options
Yes
Data can be viewed on an iPhone.
Yes
Dose-related data can be viewed on the NovoPen 6 & NovoPen Echo apps.
Duration and Storage
3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90, and work at 50ºF – 108ºF. Pods or pump reservoirs last for up to 72 hrs and work from 40ºF – 104ºF.
28-day pen (Compatible with 10-day or 14-day sensor)
Sensor lasts for 10-14 days depending on the brand, insulin pen lasts for up to 28 days. Pen has 800-injection dose memory and a five-year battery life. Sensor works between 50ºF - 113ºF and pens can be kept at room temperature for up to 28 days.

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. *Medtronic option is not waterproof. Omnipod option is fully waterproof.
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
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 integrates the Dexcom G6/G7 or Libre CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Low-profile but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.
Many components. Have to carry pens and pen needles. CGM is attached to the body.
Easy Insulin Dosing
All settings are completely customizable. Can bolus from phone or smartwatch. Can operate “open-loop” where the user must enact insulin delivery based on recommendations or “closed-loop” where modifications to insulin delivery are automatically delivered.
NovoPen 6: The maximum dose is 60 units, and doses increase in 1-unit increments. NovoPen Echo Plus: The maximum dose is 30 units, and doses increase in 0.5-unit increments
Easy to Use
Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up.
Simple design. Replaces regular insulin pen. No additional devices to add on.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available. *Medtronic pump has tubing. Omnipod is most hideable pump option (no tubes or separate controller needed).
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
