What is Fasten Health OnPrem?

Fasten Health OnPrem is a free, open-source app that helps you securely collect and manage your electronic medical records from over 100,000 hospitals, clinics, and insurance providers. Because it’s self-hosted, the app runs entirely on your device, giving you full control over your sensitive health data. With more than 15,000 monthly downloads, this trusted solution from Fasten Health and LifeValue empowers individuals and families to take ownership of their complete medical history.

01 The Problem

In today’s healthcare systems, medical information is often scattered across hospitals, labs, and clinics, making it difficult for patients to access their complete health history. Sharing information with doctors requires manual steps, printed documents, or slow data requests. This fragmentation leads to delays in care, redundant testing, and a poor patient experience.

The Solution

Tech Stack Apps developed a mobile-first medical records app for patients that puts them back in control of their electronic health data. By integrating with Fasten Health and supporting FHIR-based EHR systems, Health Wallet gives users a clean, intuitive timeline of their medical history and the ability to share selected records instantly with any Fasten-connected provider.

Smart Referral Matching

HealthScout uses OpenAI’s Assistant API to analyze patient data and recommend the right specialists. It factors in diagnosis, location, urgency, and real-time availability. Critical cases are flagged and prioritized automatically.

Cost Estimation Tools

Patients get upfront cost estimates for private referrals, along with insurance compatibility checks. This helps them plan financially before making appointments.

Seamless, User-Centered Experience

The platform guides users from registration to booking through a simple, intuitive interface. Smart prompts and visual cues help them understand and refine their input.

Clear Navigation u0026 Notifications
