Opportunity
Managing Two Apps Slowed Progress for Millions of Users
The client’s diabetes management app connected to Bluetooth® glucose meters and served users around the world. But maintaining separate Android and iOS codebases made updates complex and time-consuming—a critical issue for software regulated by the FDA.
They needed a faster, more reliable way to deliver new features and improvements without compromising safety or user experience.

Solution
From Two Codebases to One Reliable Platform
SEP analyzed the existing mobile apps, user workflows, and regulatory requirements, then recommended moving to a unified cross-platform approach. This gave the client a single, shared codebase that supported both iOS and Android while still allowing platform-specific features where needed.
To begin the transition, SEP used the client’s existing Android Java code as a foundation and converted it into C#, bringing both apps into one consolidated environment. The team rebuilt each feature, validated Bluetooth® connectivity to glucose meters, and ensured a consistent experience for users on both platforms.
This unified approach simplified testing, reduced long-term maintenance costs, and created a stronger foundation for analytics, compliance, and future updates.
