Product Background

Simple home testing for
urology patients

For the over 33 million Americans experiencing urinary health problems, finding help can be frustrating. Traditional uroflowmetry tests require a dedicated visit to a urologist’s office, where the doctor observes the patient’s flow while urinating in search of diagnostic clues. Because of the hassle and stress placed on the patient, urologists are often left to diagnose a patient based on a very limited picture of their day-to-day urinary function.

The founders of Emano Metrics saw that if patients could easily capture uroflowmetry data themselves in their own homes or workplaces, they would be willing and able to give their doctors much more information to guide treatment recommendations. So they built listening software to capture flow data based on sound, and asked us to help get it out into the world.


Connecting the docs

Emano Metrics came to us with an empowering mission and a proprietary algorithm for measuring urine flow using a phone’s microphone. Our role was to create a digital product that would allow patients to easily capture and share results with their providers; allow providers to quickly access and interpret results; and allow providers’ offices to bill for these services.

The Emano Flow uroflowmetry app connects patients and urologists to track urinary health.

A UI for the (right) ages

Building on our user research results, we designed our patient-facing mobile app with older users in mind, using clean layouts, familiar navigational elements, and large, high-contrast visuals to create an accessible user interface.


Trends on tap

Emano Flow’s provider-facing web app cleanly displays a patient’s home uroflowmetry data over time, helping doctors identify patterns and outliers to inform diagnosis and treatment recommendations.

Made to meld

To minimize demands on busy providers and staff, we created Emano Flow with ease-of-use for medical records clerks in mind, allowing for streamlined exporting and EHR importing while offering a roadmap to full EHR integration in the future.

Testing Out

With an MVP ready for field testing, Emano was able to conduct a pilot study of its Flow app in several urology practices. It has since expanded its team and is launching a rigorous clinical trial to further demonstrate the product’s accuracy.

Twenty Ideas was a tremendous asset to our early stage medical device company. From product ideation to engineering expertise, they provided us deliverables, including our MVP, and ongoing advising, helping us build our internal team. With 20i, we reached commercialization and have greatly improved our capabilities.
