San Diego-based Tandem said Mobi, the world’s smallest, durable automated insulin delivery system, can now be used with compatible Android smartphones in the U.S. via the Tandem Mobi mobile app.

In November, Tandem announced that it received FDA approval for the Android version of its Mobi mobile app. The pump, which pairs with Tandem’s Control-IQ+ algorithm, previously worked with iOS software. At the time of the clearance, it said it would commence a limited rollout before the full launch — now underway — this year.
