Salem, New Hampshire-based Agamatrix already has a popular diabetes management app available for iPhone users: The WaveSense Diabetes Manager app currently has 50,000 users, according to a report over at DiabetesMine. Like many diabetes apps, Agamatrix's requires users to manually enter glucose data. That could change soon.

Agamatrix believes that its WaveSense Jazz meter could become the first medical device to connect directly to Apple's iOS platform, which includes iPad, iPhone and iPod touch. Why isn't the WaveSense Jazz meter already sending data to the iPhone app? Agamatrix says its new USB download cable, which connects the meter to the iPhone, is currently pending FDA 510(k) review.

Agamatrix told DiabetesMine that the cable will go on sale at "Apple standard pricing" of about $25 to $30 as soon as it garners FDA approval.

“We’ve been working with Apple for the last two years to make this happen. We’re very excited,” Agamatrix's Strategic Marketing Manager Joe Flaherty told DiabetesMine.

Of course, glucose meters are already sending data to at least one smartphone platform: Earlier this year Nokia made available a smartphone app, MyGlucoHealth, in its Ovi Store that enabled Entra Health Systems' Bluetooth-enabled MyGlucoHealth meter automatically send updates to Nokia smartphone users' phones.

Johnson & Johnson company LifeScan also demonstrated a concept Bluetooth-enabled or USB-connected meter that worked with iPhone 3.0 in mid-2009. No new product has launched, however.

Meanwhile, Telcare, a recently launched startup that has at least a couple million in financing, is also working to develop a wireless glucose meter that includes wireless radios from Sierra Wireless and Qualcomm and requires no smartphone companion device. It has all the wireless embedded. The device is currently pending FDA approval, according to the company's website.
