About gWell
gWell is a preventive healthcare company focused on empowering individuals to take proactive control of their health through personalized digital wellness tools. The company's vision is to make preventive healthcare accessible, engaging, and effective for everyday users — not just those who are already health-conscious, but the broader population that stands to benefit most from early intervention and lifestyle change.
gWell's flagship product is a mobile application that integrates data from wearable devices, electronic health records, and user self-reporting to build a comprehensive picture of each user's health status and trajectory. The app uses this data to deliver personalized recommendations, track progress toward health goals, and flag potential health risks for early intervention.
gWell engaged Deerhold to design and build the core software infrastructure for their mobile application, including the data integration layer, the machine learning models powering personalized recommendations, and the consumer-facing mobile app itself.
gWell Software Development
Deerhold's software development team worked closely with gWell's leadership and clinical advisory board to translate their vision into a technical architecture and product roadmap. The engagement covered three primary workstreams:
- Data Integration Platform: Deerhold designed and built a HIPAA-compliant data integration platform capable of ingesting health data from multiple sources — including Apple HealthKit, Google Fit, Fitbit, Garmin, and other popular wearable platforms — as well as clinical data from EHR systems via FHIR APIs. The platform normalized incoming data to a consistent internal schema and stored it securely in a cloud-based health data repository.
- Machine Learning and Analytics: Deerhold's data science team developed the machine learning models that power gWell's personalized recommendation engine. These models analyzed each user's health data — including activity levels, sleep patterns, nutrition, vital signs, and clinical biomarkers — to identify patterns associated with elevated health risks and to generate personalized wellness recommendations.
- Mobile Application: Deerhold designed and built gWell's consumer-facing mobile application for both iOS and Android. The app was built using React Native to enable code sharing across platforms while delivering a native-quality user experience. The app featured a clean, intuitive dashboard displaying the user's health metrics, personalized recommendations, progress toward goals, and upcoming health reminders.
How gWell Works
The gWell application guides users through a structured onboarding process that collects baseline health information and connects the app to the user's existing health data sources. Once onboarded, the app operates continuously in the background, ingesting data from connected devices and periodically prompting users to self-report additional health information.
The core of the gWell experience is the personalized wellness dashboard, which presents each user with:
- A Health Score — a single composite metric reflecting the user's overall health status across multiple dimensions, including cardiovascular health, metabolic health, sleep quality, mental well-being, and physical fitness.
- Trend visualizations showing how each health dimension has changed over time, enabling users to see the impact of their lifestyle choices and interventions.
- A personalized action plan with daily and weekly recommendations tailored to the user's health profile and goals — ranging from exercise and nutrition guidance to sleep hygiene tips and stress management techniques.
- Risk alerts that notify users when their health data suggests an elevated risk for a specific condition — for example, a trend toward pre-diabetic blood glucose levels — and recommend appropriate follow-up actions, including consulting a healthcare provider.
gWell also includes a social features layer that allows users to connect with friends and family, share progress on health goals, and participate in wellness challenges — leveraging the power of social motivation to drive sustained engagement with healthy behaviors.
