How does a smart pen compare to traditional insulin pens?


A traditional insulin pen allows you to dial doses and deliver insulin. A smart insulin pen goes a step further and uses Bluetooth® technology to send dose information to a mobile app on your phone. It offers dose calculations and tracking, plus many more features that help make managing diabetes easier. Review the full list of benefits below:

InPen™ helps reduce the mental math of diabetes management.


How does it work?

The InPen™ system helps you take the right amount of insulin, at the right time. It calculates personalized meal and correction doses - considering your insulin sensitivity, insulin-to-carb ratio, and active insulin levels for each dose recommendation. The system also logs doses on a mobile app, allowing you to see your dose history on a smartphone.

Frequently asked questions


The InPen™ is the only FDA-cleared smart insulin pen that combines the freedom of Bluetooth® technology and intelligence through an easy-to-use smartphone app, helping people administer correction and mealtime insulin doses.Φ

InPen™ is a prescription-only device. Eligible patients with commercial insurance may pay as little as $35 per prescribed InPen™. Each InPen™ is reusable for one year. Terms and conditions apply. Learn more.

Cartridges are not included with InPen™. You’ll need a separate prescription for cartridges. Cartridges can be ordered from the same pharmacy where you get your other diabetes supplies. InPen™ is compatible with Humalog, Novolog, and Fiasp U-100 3.0 mL insulin cartridges.
The InPen™ smart insulin pen only works with short-acting insulin; it is compatible with Novolog, Humalog, and Fiasp. The InPen™ app allows you to manually log long-acting insulin doses and set up dose reminders to take your long-acting insulin.

Yes, you can pair as many InPens as you need to the app. This enables the flexibility for you to have one InPen™ at home and another at work or school.

Note: Make sure your paired device is within range of your InPen™ when you dose. Your InPen™ app will automatically sync doses from all paired InPen(s) when within range.

Active insulin, also known as insulin-on-board (IOB), is an estimate of how much insulin from recent doses is still active in your body. For example, if you take a 5-unit dose, there will initially be a full 5.0 units in your body. Over several hours this will decrease as your body uses the insulin. The InPen™ app shows active insulin from rapid-acting or mealtime insulin only, not long-acting or basal insulin.
Active insulin is shown on the home screen below the calculate dose button. This number shows your total active insulin based on all rapid-acting and mealtime doses from the past eight hours.
Yes, the i-Port Advance injection port is compatible with the InPen™. Needles used with the i-Port Advance injection port need to be 5-8mm (3/16-5/16”) in length and 32-28 gauge.
Yes, the integration is compatible with both iOS and Android devices; however, you should check compatibility for both the Guardian Connect system and the InPen™ app prior to ordering.
