Developed in partnership with Sanofi, iBGStar was the first FDA-cleared blood glucose monitor that connected directly to the iPhone® (back in the 30-pin connector days). It worked in conjunction with the iBGStar Diabetes Manager iPhone app.

Design challenges

The iBGStar interface had unique challenges due to the small size and overall design of the device.

Small screen size

One challenge with this meter was determining how to display all necessary information on a very small screen.


In order to maximize distribution potential, the meter was designed with almost no text (just numbers and icons).

One button

With only one button, the meter’s functionality was kept to a minimum to create a streamlined user experience.
