MileIQ is a mobile SaaS application that automates mileage tracking for self-employed professionals and small business teams. The app passively detects each drive, logs the route and distance, and generates IRS-compliant mileage reports — all without requiring user input.
However, behind it was a legacy Objective-C codebase that had become increasingly difficult to manage. The outdated architecture strained devices, slowed the release of new features, and made it costly to maintain long-term. With thousands of active users, MileIQ needed a major technical upgrade without compromising performance or user trust.
MileIQ chose Relevant Software for our ability to modernise large-scale mobile apps without downtime and our deep expertise in Swift architecture, performance tuning, and secure iOS development. Our experience with finance-focused platforms and high-stakes delivery made us a reliable partner for a seamless, audit-ready migration.
The task was clear: rebuild the mobile core in Swift while maintaining real-time drive detection accuracy. This also meant improving UI performance across devices and aligning the app with Apple’s latest security and performance standards, with no disruption to users who relied on MileIQ daily.
