DIMO
Optimizing iOS performance & Bluetooth communication
Overview
The project’s primary goal was to bring DIMO’s iOS application up to par with its Android counterpart. Profiling and analysis revealed key performance bottlenecks and technical debt. Addressing these issues improved app responsiveness, Bluetooth communication, and overall reliability across devices.
Solution
By rewriting state management, rebuilding the Bluetooth protocol layer, and introducing a library of reusable components, the iOS app became faster, scalable, and far more stable, resulting in improved retention and user satisfaction.
