About project
Checked In is a cross-platform healthcare application designed to help patients quickly access medical assistance in urgent and emergency situations.
The app allows users to locate nearby emergency rooms and medical facilities, find suitable healthcare providers, and book appointments directly from their mobile devices.
By combining location-based search, provider matching, and appointment booking in one interface, Checked In helps reduce the time and stress involved in finding appropriate medical care.
The product was designed for both iOS and Android, with a strong focus on accurate geolocation, intuitive navigation, reliable performance, and a smooth user experience.

Here’s the Result
- faster access to medical care — users can quickly locate nearby emergency rooms and medical facilities based on their current location.
- reduced search friction — the platform combines facility discovery, healthcare provider matching, and appointment booking within one mobile application.
- more relevant provider selection — a matching algorithm helps connect users with suitable medical providers based on their needs and proximity.
- cross-platform accessibility — the application delivers a consistent experience across both iOS and Android devices.
- streamlined appointment booking — users can schedule appointments directly through the app instead of relying on separate services or manual communication.
- real-time functionality — third-party APIs support location tracking, medical facility search, and booking-related processes.
- scalable mobile development — Expo and React Native enabled faster development, testing, and deployment across multiple platforms.
- consistent product quality — automated formatting, linting, type checks, and pre-commit controls helped maintain a reliable codebase throughout development.
Here’s What We Did
- developer Experience setup
We configured ESLint, Prettier, and Husky pre-commit hooks to maintain consistent code quality and simplify collaboration across the development team. - geolocation functionality
We implemented GEO-points to determine the user’s current position and accurately display nearby emergency rooms and medical facilities. - customer-provider matching
We developed matching logic to connect users with the most suitable medical providers based on their needs, location, and available services. - full frontend implementation
We developed the application interface based on the approved Figma designs and adapted the layouts for mobile use. - application navigation
We integrated React Native Navigation to provide fast, intuitive, and consistent movement between app screens. - cross-platform development
We used React Native and Expo to deliver the application for both iOS and Android from a shared codebase. - third-party API integrations
We connected external services for real-time location tracking, medical facility discovery, and appointment booking. - performance optimization
We optimized the application to ensure stable behavior and a consistent user experience across different devices. - testing
We implemented unit and integration testing to improve reliability and reduce the risk of errors in core user flows.
Roadmap
Foundation Setup
-
We prepared the project architecture and development environment. ESLint, Prettier, and Husky were configured to maintain consistent coding standards, while pre-commit hooks were added for automated checks.
Core Functionality Development
We implemented GEO-point functionality for locating nearby medical facilities and developed the core matching logic between patients and healthcare providers.
Frontend Implementation
-
We conducted unit and integration testing, connected third-party services for location tracking and appointment booking, optimized cross-platform performance, and prepared the application for deployment on iOS and Android.
Testing, Integration, and Deployment
