This Is A Serious Issue Which Needs A Higher Level Of Public Awareness.

With an estimated 100,000 health and fitness apps available on the two leading smartphone platforms, iOS and Android, it seems there is an app for everything – from tracking your bowel movements, to practising your pimple-popping technique.
However, a number of apps are starting to raise the ire of government regulators. Brain-training juggernaut Lumosity was recently fined US$2 million (A$2.7 million) for making unfounded claims that its app could improve work performance and delay the onset of Alzheimer’s.
“Ultimeyes”, a vision-training app touted to “turn back the clock on your vision” and reduce the need for glasses and contact lenses, was fined US$150,000 for misrepresenting scientific research and ordered to stop making deceptive marketing claims.
“MelApp” claimed to be able to assess melanoma on the basis of a photograph of the mole and some other inputted information, analysed using “patent protect, highly sophisticated mathematical algorithms and image pattern recognition technology”. The US Federal Trade Commission (FTC) found its claims lacked scientific evidence, leading to a hefty fine and strict instructions regarding future marketing.
To date, authorities have primarily pursued rogue health apps from a consumer rights perspective, on the basis of misleading advertising – that is, the apps claiming to do something when, in fact, they may be ineffective – rather than from a medical-safety perspective.
In the US, the Food and Drug Authority (FDA) is traditionally responsible for approving medical devices. However, apps that essentially allow a smartphone to become a medical device present a grey area. The FDA has issued guidelines, but compliance is primarily voluntary. Only a minuscule percentage of apps available in the Apple and Google Play stores have FDA approval.
Most apps that present themselves as substitute medical devices offer fine-print disclaimers, such as “not FDA cleared” and “for entertainment purposes”. This information is buried in the expandable description of the app on the app store, which most users will never read.
An interesting case in point is the hugely popular “Instant Blood Pressure” app, which has sold an estimated 148,000 copies. This app and others like it claim to read blood pressure – “no cuff required” (instead, the app supposedly uses the phone’s microphone pressed against the chest and a finger over the camera).
Independent testing published in March’s JAMA Internal Medicine found the app failed to identify high blood pressure in around 80% of true cases.
This is disturbing, considering such apps are likely to appeal to people with high blood pressure. It is conceivable that users could delay seeking medical attention on the basis of false normal-range readings, with potentially dire consequences.
So in this ever-expanding and largely unregulated app landscape, how can you go about distinguishing the good health apps from the bad?
Medical diagnostic equipment is highly specialised and specific, stringently tested and usually interpreted by skilled professionals. It’s therefore highly dubious that a smartphone app can match these diagnostic capabilities, based on the in-built microphone and camera, and interpretation by a commercial algorithm (which is typically unpublished and unproven).
While apps exist that claim to treat conditions such as pain, acne and seasonal affective disorder using smartphones’ vibrations and/or screen light (yes, really, and they’ve had thousands of paying downloads), such outputs lack scientific evidence and are extremely unlikely to be of therapeutic quality or intensity.
Affiliation with a reputable peak body, university or government department suggests the app is likely to be trustworthy. Beware, though, sneaky developers have been caught out inaccurately associating their app with leading universities (when, in fact, they simply studied there years earlier). Also, endorsement from obscure bodies shouldn’t convey confidence.
Self-monitoring, goal-setting and feedback are well-established techniques for boosting motivation and facilitating behaviour change. Such techniques are commonly offered in health apps and are likely to be useful for both people working on health goals that they wouldn’t normally see a doctor for (such as increasing fitness) and people self-managing a health condition in consultation with their doctor.
If reviews are bad, the app probably doesn’t work well, so give it a miss. However, good reviews aren’t necessarily a sign that an app is fundamentally trustworthy.
Simply, don’t. While many apps contain sound medical information, they are no substitute for a consultation with a doctor. If you have a health concern, you should see a GP.
The landscape of smartphone health apps is quickly evolving, and regulators are struggling to keep pace. There are many outstanding apps to help people improve their health. My advice? Have fun experimenting with health and fitness apps – just be sure to bring along a healthy dose of common sense and scepticism.
And remember, an app does not put a doctor and specialist medical lab in your pocket.

Most of us have smartphones jammed with apps that promise to improve our lives by tracking our sleep, finding the best coffee spots or, more annoyingly, reminding us it’s time to go for a run.
Many are fun and entertaining, but some are for more serious medical purposes.
An estimated 165,000 medical apps are on offer that range from measuring blood pressure to helping manage conditions such as diabetes, asthma and mental health.
While some are helpful, for the most part, this field of mobile personalised healthcare is untested, unregulated, possibly ungovernable and occasionally dangerous.
A study by the University of NSW Black Dog Institute discovered that of the 120 suicide prevention apps they looked at, none provided comprehensive evidence-based support and some even contained dangerous advice.
“Of greatest concern is the encouragement to engage in risky behaviours such as drugs and deliberate self-harm to manage a crisis,” said the researchers writing in PLOS One in April.
Two years ago, US emergency specialist Dr Iltifat Husain, an expert in digital medicine, was highlighting the problem.
A review he carried out for the iMedicalApps website on a popular $3.99 blood pressure app, which used the iPhone’s camera and microphone to secure a reading, found it simply didn’t work.
With clinical trials taking years to design, run and produce results, it seems that traditional scientific evaluation methods cannot keep pace with the speed of developments in digital health apps.
“This lengthy process simply isn’t viable in the current app marketplace where the focus is on rapid delivery rather than proof of effect,” noted the Black Dog Institute researchers.

That we can have popular apps that simply do not work says it all - people need to be very careful with anything they download. The advice in the first article needs to be carefully considered and acted upon.
