One Drop To One Health - A Flexible Health Platform

Recruited to lead product design for One Health's novel biosensor platform, a minimally invasive CGM targeting the 95% of T2 patients priced out of existing continuous glucose monitors. Over two years I led the UX for a Class II medical device app on its path to 510(k) clearance, directed a full company rebrand from One Drop to One Health, and architected the switch to a scalable multi-condition digital health platform for the existing app with over 1.5M users.

The Context of Type 2 Diabetes

The T2 Data Problem

95% T2 Patients Don’t have access to Continuous Glucose Monitors (CGMs)

Why?:

↳ CGMs are designed for T1 and aren’t perfect for T2 use cases

↳ CGMs are too expensive and not covered by payers.

The Biosensor Solution

Bringing Continuous Data To T2

Why?

↳ Access to continuous data is proven to speed up and improve health outcomes in T2 patients.


How?

↳ Lower costs through re-usable battery and transmitter units.

↳ Flexible wear times can better adapt to T2 needs.

Goals

1

Sensor Management and Data

Design Biosensor live data streaming and hardware management (charge levels, replacement, etc.)

2

Future Proof Brand

Pivot the branding and messaging to accommodate the new hardware and product strategy.

3

Scalable Health Platform

Inform the product strategy for the broader digital platform so it scales as we leverage the biosensor data.

Scope And Constraints

The new Biosensor was required to have its own app separate from the main One Drop app. This was because the FDA considers the app itself as part of the medical device sold alongside the hardware.

  1. Sensor Management and Data

Sensor Management

The biosensor's dual-battery system, two units charged in sequence to maintain 24-hour wear, was tricky for a non-tech-savvy T2 audience. We kept instructions simple, focusing on wear time rather than percentages, always surfacing the status of the off sensor battery to remind the user to keep it charged.


For tutorials, rather than lean on static diagrams or text instructions, we opted for a step by step talking-head video tutorial format. We workshopped a full storyboard before shooting ourselves, covering unboxing, application, and recurring wear.

Live Data

For the data interface we deliberately pulled from established CGM conventions, using a cleaner version of the 3-hour line graph and range visualisation familiar from Dexcom and Abbott, to avoid alienating users migrating from other platforms.


Multi-data support was architected similarly to Apple Health's card model: data types surface as active or inactive cards depending on what the sensor is currently measuring, keeping the interface uncluttered for single-condition users while remaining extensible for future data types.

2. Future Proofing The Brand

Scope And Constraints

One Drop’s name was based on their current hardware. With the Biosensor promising to broaden the horizons of the company, it needed a name which would not limit it to any one piece of hardware or health condition.

My Contributions

Coming up with a name bigger than diabetes: One Health

Informing the brand team how Biosensor would affect positioning: whole body, pro-active health care.

Creative direction of the photography, color system and hardware CMF

3. Scalable Health Platform

Scope And Constraints

The Biosensor opened the opportunity to serve T2 and other conditions with the same hardware platform. Therefore we needed a digital strategy that could adapt to multiple use cases.


An iterative approach had to be taken to avoid suspending service to existing users.

My Contributions

Worked directly with C-Suite team on conceptualizing a Biosensor enabled platform.

Worked with product management and engineering to create an iterative development road map.

Leading design team to set up an adaptable UI system.

Scalable product strategy

The north star was replacing data-heavy dashboards, inappropriate for our audience, with a flexible card feed that surfaces the right action at the right moment, guiding users through their health journey without requiring them to interpret raw data themselves.

Roadmap for Integration Into The Existing Platform

We approached the transition in three deliberate phases. 

  • First, we built robust data visualization capabilities so the platform could surface meaningful visual correlations.

  • Second, we introduced fixed program tracks to re-engage users following diagnosis, providing structured guidance during the highest-anxiety period. 

  • Third, we developed trend-detection logic to generate contextual nudges outside of structured programs, maintaining engagement without demanding perpetual attention from users.

Conclusion

Over two years we successfully brought a novel CGM system to clinical trials, rebuilt the brand around a multi-condition platform vision, and architected a scalable digital health ecosystem.
