mhealthDespite its relative infancy, the crowded mobile healthcare app market features a handful of well-established veterans and a plethora of newcomers scrambling for visibility and traction among consumers and medical professionals. The market includes more than 100,000 apps, according toResearch2Guidance — and the flood of new entrants shows no sign of easing, says Ralf-Gordon Jahns, founder of the Berlin-based research firm, in an interview.

“Mobile technology is truly revolutionizing the future of healthcare, and mobile apps in particular have played an important role in improving communication between physicians and patients, increasing adherence to medical prescriptions, helping patients locate good doctors and pharmacies, and encouraging preventative measures,” says Jeff Holleran, senior director of Enterprise Product Strategy at BlackBerry. “Both doctors and patients are finding that mobile apps can provide a fast and efficient way to stay in touch and exchange information. Providers are leveraging apps so that they can respond quicker and share data faster. On the consumer side, mobile apps are growing in popularity as people become increasingly more conscious about their health and well-being.”

Although some apps have a clear lead in categories such as running, fitness, and nutrition, that hasn’t stopped new contenders from releasing their own offerings. They may offer a new perspective — anything from being chased by zombies to focusing on strength training for women — or target a specific group of often neglected users, such as owners of BlackBerry or Windows mobile devices.

Health tracker Nudge, for example, recently moved away from Web-based apps in order to focus all its resources on mobile health apps. The developer created an algorithm based on recommendations from the US Department of Agriculture, the US Centers for Disease Control and Prevention, and the World Health Organization, and applied research from an internal team of health professionals to index data input by users, says Phil Beene, co-founder, in an email.

“This means that no matter what apps, trackers, or wearables a person is using, they can compare an indexed score, called the Nudge Factor, to friends and other users on the app,” added Mac Gambill, co-founder of Nudge, in an email. “By tracking dietary intake, hydration, exercise, and sleep duration, as well as syncing with the leading apps and wearables, Nudge is becoming the principal curator and indexer of the best health and fitness apps on the market.”

New and existing developers fit into six general categories, Research2Guidance found. They include:

1. Established healthcare players — such as pharmaceutical, insurance, and healthcare companies — which represent about 3.4% of app publishers. Usually larger organizations, they typically publish many mHealth apps but have a below-average reach in terms of downloads.

2. App specialists are generally smaller developers that entered mHealth to leverage their software expertise. Although they usually have a small share of medical expertise in-house, they account for 14% of the mHealth app publisher community.

3. Helpers, which represent 32% of this space, are small companies that want to help others. Revenue is secondary, and could be one reason 61% had fewer than 5,000 downloads in 2013.

4. Medical specialists use their expertise to develop mobile apps and claim one fifth of the market. This group had the largest number of companies that earned more than $1 million from their mHealth apps last year.

5. Fitness specialists joined the market to earn money, and they account for 10% of this space. Often they connect to medical databases and sensors and use app development tools.

6. Connectors create value-rich apps that integrate with other apps, sensors, and databases, enabling them to generate the highest average revenue. They account for 18% of the mHealth developer community.

Combined, mHealth apps will be worth about $26 billion by 2017 — but that’s just the beginning of mobile apps’ impact on the vast healthcare market, estimated at $6 trillion, Jahns says.

“The $26 billion is the tip of the iceberg. The huge potential is: ‘Do apps allow [the healthcare industry] to save costs, for example, hospitals to send out patients earlier so they can use the beds for somebody else? Or do they reduce the amount of doctor visits?’ The true potential is reducing costs and making the healthcare market more efficient,” he says.

Of course, consumers might argue their goal is losing weight, eating healthier, monitoring medications, or protecting themselves from bugs.
