DFree Health Tech Wearable Device Support for Android Phones and Tablets Now Available

Helps Manage Urinary Incontinence -- Notifies You When It’s Time to Go

SAN DIEGO, November 15, 2018 – Triple W, an innovator of connected health devices, today announced the availability in the U.S. market of an Android version of the companion app for DFree®, the first wearable device for incontinence that notifies the user when it’s time to go to the bathroom. With DFree, seniors, children and disabled people with bladder control issues have a convenient and cost-effective alternative to disposable diapers or pads and medications. DFree gives them freedom to live an active lifestyle with peace of mind from accidents.

The iOS® version of DFree is currently used in over 500 senior care facilities in Japan, Europe and the U.S. since 2017. DFree stands for “diaper-free.” According to the U.S. National Institutes of Health, urinary incontinence affects 500 million people worldwide.

“With DFree, you can anticipate the best time to use the bathroom based on how full your bladder is in real time and customize the notifications schedule based on your own mobility and environment,” said Atsushi Nakanishi, President and CEO for Triple W. “For example, if you need a little extra time to get to the bathroom or anticipate a line in a public restroom, you can set up DFree to notify you on your smartphone or tablet when your bladder is 50 or 60 percent full.”  

DFree was recently released in the U.S. market with the iOS companion app.  “With the release of the Android version of the companion app, we’re able to offer our product to the majority of mobile device users who can potentially benefit from our technology,” said Nakanishi.

How DFree Works

The lightweight and portable DFree device may be discreetly clipped on your belt or clothing while the non-invasive ultrasound sensor is secured to the lower abdomen with medical tape. The sensor uses nonharmful ultrasound technology to monitor the change in bladder size and predicts urination timing using a patented algorithm. DFree connects via Bluetooth® to a smartphone or tablet and sends notifications via the DFree app -- informing the individual or caregiver, when it’s time to go to the bathroom. The user sets the threshold of when they want to be notified such as when their bladder is 65 percent, 70 percent or 85 percent full.

The DFree device weighs approximately 2.5 ounces. The attached wireless ultrasound sensor weighs just over a half ounce and is approximately 2 x 1 x .5 inches. The device is bundled with a USB cable for charging.  DFree has a built-in lithium-ion rechargeable battery. A battery charge lasts approximately 24 hours under normal usage and can be fully charged in four hours.


DFree is available now in the U.S. from the DFree website, Amazon and authorized retailers for $499.99 (MSRP). The DFree app may be downloaded for free from the App Store and Google Play. The app supports iOS devices (iPhone, iPad, iPod) running iOS version 10 or later and Android devices (phones, tablets) running Android 4.4 or later.
