About InPen

Healthcare Professionals


Discover the InPen smart insulin delivery system, a step forward in integrated diabetes management.

InPen combines our innovative diabetes management app with our Bluetooth®-enabled pen injector to simplify the constant tracking, monitoring, and calculating required for insulin therapy. With InPen, live life, less complicated.

InPen works like other pens, it’s just smarter.

Use InPen like any other pen injector. The difference is InPen tracks each dose and delivers your data to a secure app on your smartphone. Finally, no complicated math and no logbook to update.

Know where you stand with your diabetes care plan.

The InPen app displays your active insulin, blood glucose, and last insulin dose. It also reminds you when to take a dose, calculates and recommends your next dose, and warns you if your insulin is expired or has been stored outside of the recommended temperature range.

Eliminate guesswork with an integrated dose calculator.

The InPen App does the math for you. The InPen dose calculator recommends a dose based on current blood sugar and carb intake, and adjusts for active insulin from previous doses (IOB).

The InPen Mobile App is a free download on Apple iOS or Android.

The InPen is a great solution...

“The InPen is a great solution to the real world problem of people with diabetes. It provides exactly what's needed: time and dose, how much insulin activity remains at a particular time, and an accurate history… a perfect solution.”

- John Walsh, PA, CDE

Closes the capability gap...

“Having insulin dosing information for patients on multiple daily injection therapy would be very helpful to me as a provider making management decisions. More importantly, it will close the capability gap between injection and pump therapy, bringing many of the benefits of a pump (bolus calculator, insulin-on-board) to the vast majority of patients who do not use one. ”

InPen fills an unmet need...

"Despite the availability of pumps and pens, which are both important products, there remains an unmet need for the majority of folks who use pens to deliver their basal and meal time insuIin. Insulin pens should have many of the features and advantages the pump wearers enjoy. InPen fills this need in a simple and intuitive way, something I personally and many of my colleagues with type 1 diabetes appreciate. I look forward to being able to provide my patients the option of a dose calculator and automatic logging in the form factor of a pen."

The InPen Answer...

"InPen is the answer to a great clinical need with wireless data communication and dosing algorithms that are safe and effective.”

I have a lot more freedom...

"I’m a firefighter and I always used to worry about my pump being damaged while on shift. Now that I use InPen, I have a lot more freedom while at work and I worry less about my diabetes. Because the InPen App provides all the same technology of a pump at a small fraction of the cost, I would highly recommend it."

- Kyle K., Firefighter

InPen is a game changer...

"I think InPen is a game changer for anyone on multiple daily injections. I feel more in control of my diabetes because now I am confident that I am administering the right doses. I am also avoiding stacking which means less blood sugar roller coasters. I can’t imagine going back to MDI without InPen in my toolbox and highly recommend this to anyone else who prefers injections over the pump."
