The Problem

As the concept evolved, the client encountered several challenges that needed to be addressed before launching a reliable iOS application.

1

Disconnected Medical Information

Users were managing prescriptions, reports, and health records across multiple platforms, making it difficult to access complete and up-to-date information in one place.

2

High Data Security Requirements

Healthcare data demanded strong security measures, including encrypted communication, secure storage, and strict access control to meet platform and privacy standards.

3

Complex User Experience

Existing health apps were often difficult to navigate. This led to low adoption and limited engagement from users who wanted simplicity and clarity.

4

Performance and Scalability Concerns

The app needed to support growing user volumes, large medical files, and real-time access without compromising speed or stability.

The Goal

The goal was to build a secure and easy-to-use iOS application that enables users to store and manage their health data effortlessly while ensuring strong performance, data privacy, and scalability for future growth.

Our Solution

iOS App Architecture

For the iOS version of iMed, we used Flutter to build a high-performance application that delivers a native-like experience on iPhones and iPads. The architecture was designed to align with iOS platform behavior, ensuring smooth animations, responsive UI, and consistent performance. A modular structure helped keep features independent and easy to scale over time.

Data Security & HealthKit

Security was a core focus due to the sensitive nature of healthcare data. We implemented secure authentication, encrypted API communication, and protected local storage on iOS devices. Apple HealthKit was integrated using platform-specific plugins, allowing users to sync health data while maintaining strict permission control and compliance with Apple’s privacy guidelines.

Backend & Real-Time Sync

The iOS app was connected to a scalable backend infrastructure to support real-time access and cloud-based synchronization. API interactions were optimized to follow iOS lifecycle and battery usage best practices. This ensured fast response times, reliable data sync, and stable app performance as user activity increased.

Result

After launch, the iMed iOS application delivered measurable improvements across usability, engagement, and system stability.

Improved User Adoption

The simplified onboarding and intuitive interface helped increase user sign-ups and reduced drop-offs during first-time usage.

Higher App Stability and Performance

Crash rates dropped significantly, and the app maintained consistent performance even with increasing data volume and active users.

Better User Engagement

Users spent more time within the app managing records, tracking health data, and using integrated features, leading to higher retention rates.
