Social entrepreneur Ariel Beery and optics expert David Levitz had the inspiration to use the built-in camera of a smartphone to screen for cervical cancer — the fourth most common cancer affecting women globally and the second most common cancer for women in low-resource settings.

“More than five billion people around the world have access to mobile phones, but not to a physician,” Beery told ISRAEL21c in 2014, when the prototype was being piloted in five countries.

“We can do what a $100,000 device can do on a mobile phone, with 10 times better magnification than using just the naked eye, raising diagnostic accuracy significantly.”

Today, the EVA point-of-care device from MobileODT is used by primary care providers in 30-plus countries to conduct specialist-level visual screenings for thousands of women.

“MobileODT was the first company to build an FDA Class 2 medical device — a regulated medical device that replaces an existing medical system — around a mobile phone,” says former MobileODT CEO Beery, now general partner at CoVelocity Health, a strategic commercialization partner for medical technologies.

Since then, many other companies have harnessed the mobile phone – either to help healthcare professionals gather data (as with MobileODT) or to help patients transmit data from home to the practitioner and facilitate communication during a remote exam.

“There are a number of reasons why mobile phones make sense to be the core platform for a medical device,” says Beery.

“The first one is that every single person on the planet knows how to use one. And that is so important, because training and onboarding for a medical device is very difficult. When you have something based on a mobile phone platform, it’s relatively easy for the practitioner to watch a few tutorials and very quickly start using the device. That’s not the case with anything else, and it’s super important because then you can expand into rural areas and low-resource settings efficiently.”

There are other advantages of using smartphones for healthcare.

“From a regulatory perspective, most mobile phones in the market have received both electrical testing and broadcast certificates. Wi-Fi is intermittent around the world, but when you have a SIM card and a device that will be connected or integrated with medical information systems, a mobile phone shortcuts a whole host of regulation and registration — things that are really hard and expensive to do,” Beery adds. “For any [medical] device that requires communication, mobile phones already have all that already baked in.”

Below are descriptions of 13 companies using the smartphone as a basis or adjunct for smart healthcare.

Beery and Levitz originally envisioned EVA as a colposcope addon for the healthcare practitioner’s own phone. The current version instead has a dedicated Samsung J530 built in for all-in-one visualization, documentation and teleconsultation.

“We learned that there’s a big difference between things that assist a health worker in decision-making or communication functions, where using their own mobile phone makes sense; and information-gathering or diagnostic functions, in which case a dedicated mobile phone makes sense,” Beery explains.

“Diagnostic functions require your device to touch the patient. That brings up issues of security and sterilization. Also, a dedicated phone doesn’t have the same wear and tear and memory issues that you have with someone’s personal phone and doesn’t conflict with their images and WhatsApp and what have you.”

The EVA product line now includes separate devices for cervical cancer screening, cervical examination and sexual assault forensics. It’s also used to train clinicians in colposcopy; telecolposcopy or remote colposcopy.


Remotely or onsite, Binah.ai’s video-based solution provides medical-grade vital signs measurements — heart rate, heart rate variability, mental stress level, oxygen saturation, respiration rate and more — within 2 minutes via a video of the patient’s upper cheek taken with a smartphone, tablet or laptop.

The signal processing and AI technology compensates for motion and imperfect lighting, and supports any age, gender and skin color. It can even detect subtle changes that might otherwise go unnoticed. Binah.ai works with healthcare, insurance and wellness industries in several countries.

Binah.ai is headquartered in Ramat Gan with offices in Maryland and Tokyo.


This Tel Aviv-based startup, founded in 2013, leverages the image-processing capability of any smartphone camera for four at-home Minuteful medical tests – kidney function, wound management, urinary tract infection and urinalysis — whose results are transmitted to the clinician instantly.

Healthy.io’s partners in the US and UK include, among others, the National Kidney Foundation, the National Health Service, Modality and the Boots chain. The company recently acquired its American competitor, Inui Health, for $9 million.

Sweetch is a mobile based digital coach providing personalized recommendations for preventing and managing chronic conditions, generated from analysis of millions of datapoints on the individual’s smartphone and other connected devices.

In addition to the Sweetch app, the technology is available as a white-label app or as an SDK to be integrated within an existing app. Headquartered in Tel Aviv, Sweetch is used in countries across the world.


Montfort bridges technology and neurology, turning any standard smartphone into a personalized neurological medical testing device.

Using smartphone sensors and AI, Montfort’s EncephaLog app provides FDA-cleared digital neurological tests for early diagnosis of conditions such as Parkinson’s disease, Huntington’s disease, anxiety, depression, post-Covid-19 neurological symptoms and more.

In the app, patients see the specific tests prescribed with reminders about when to take the tests and instructions in the patient’s preferred language. Montfort is used in more than 10 countries.

The tests measure parameters in three dimensions — motor (such as balance, gait, tremor), cognitive (memory, response time, pattern recognition) and mood indicators. It merges those measures with a fourth dimension of physiological records (genetics, brain scans, data from wearable devices) for a holistic picture.


Nonagon, backed by Phillips and Teva, has FDA and CE approval for its smartphone-based telemedicine device.

Four embedded sensors interface with the user’s smartphone to provide readings of nine common tests required for primary medical care: a stethoscope check (lung, heart and bowel sounds), otoscopy of the ear, oximeter (pulse rate and saturation), thermometer (body temperature), and a throat and skin test that uses the smartphone’s camera.

The device works with patients as young as two years old. The clinical data is sent in real time to the physician, enabling near immediate diagnosis, referral or prescription. Formerly known as MyHomeDoc, Nonagon is based in Caesarea with offices in New York.


This company’s award-winning TytoHome remote exam device ties in with the user’s and physician’s iOS or Android smartphone (or other device) via an app that allows the practitioner to control and guide the entire exam in real time.

For example, the clinician can take control of the stethoscope adapter to listen to lung and heart sounds or use the otoscope adapter to check ears for infection. After confirming a diagnosis, the clinician can send further instructions or a prescription.

Lumen’s handheld device allows users to analyze and monitor their metabolism with their smartphone. It reveals the body’s current source of energy — fats or carbs — on a scale of 1 to 5, based on the respiratory exchange ratio.

The score helps users adjust their daily diet and physical activities accordingly: Low-carb days decrease the insulin spike, improving insulin sensitivity and enhancing mitochondrial function, while high-carb days ensure the body’s ability to use carbs for energy and keep hormones in balance.

This app built on eye-tracking technology from Jerusalem-based Umoove http://www.umoove.me/ helps thousands of users “reset” their response to depression, trauma, anxiety, stress and other emotional triggers.

An audio guide takes the user through each daily two-minute session of a 10-day program tailored to specific conditions. The eye tracker on the phone’s camera detects patterns in eye movement that indicate a stress trigger. Users are directed to do certain tasks with their eyes that interrupt the pattern and thus create a therapeutic effect by clearing the triggers.

The unique method behind the app was published last November in the journal Frontiers.

Yitzi Kempinski, founder-CEO of Umoove and CTO of MindReset, says results are so encouraging that the company is researching other ways people can use the app, such as for work burnout or emotional barriers to learning.


Using ocular metric data captured with a standard webcam or smartphone, this Tel Aviv- and Texas-based startup is building an AI-driven platform to accelerate and improve drug development and patient monitoring, as well as introduce precision care for patients with neurological disorders.

A physician records a five-minute video of a patient’s eye movements. Neuralight’s imaging tools clean up the video, then artificial intelligence and machine learning decipher what’s behind the eye movements.

The concept is based on scientific studies over the past 20 years showing correlations between various oculometric measures and the neurological status of patients suffering from a range of neurodegenerative and psychiatric disorders.

Cordio Medical 

Cordio Medical’s HearO technology can sense fluid accumulation related to congestive heart failure through a patient’s speech and send an alert. This noninvasive monitoring solution is based on true speech signal processing augmented with machine learning.

The user speaks into a smartphone app whose algorithms allow near real-time monitoring and early detection of condition deterioration. The system is patient-tailored, constantly learning the patient’s voice. HearO noninvasively.

The company recently raised $18 million and aims to enter the US market in 2024.
