Services
Alongside custom app development, FirstSecond offers focused services to improve, modernize and maintain mobile products.
Tailor-made mobile apps
FirstSecond builds entirely custom iOS applications that fit your product, users and technical constraints. The focus is performance, maintainability and usability. Apps can also extend to watchOS, tvOS, macOS and visionOS when it makes sense for the product.
On-site consulting
Need senior mobile expertise inside your product team? Work directly with a freelance iOS expert for native Apple platform delivery, technical direction and developer coaching.
Quality & performance audits
If your app feels slow, fragile or hard to evolve, FirstSecond reviews the codebase, architecture and runtime behavior, then turns the findings into clear, actionable improvements.
App modernization
Older apps often need more than a quick bug fix. FirstSecond updates dependencies, improves project structure, prepares App Store submissions, adds CI/CD where useful, and makes maintenance predictable again.
How we work
A pragmatic way of working for mobile products that need to move quickly without compromising quality.
Iterate quickly
Work happens in short cycles with visible progress, TestFlight builds and regular feedback so decisions stay grounded in the real product.
Design for the platform
Interfaces are built to feel native on iPhone, iPad, Mac and Vision Pro, with attention to Apple guidelines, accessibility and everyday usability.
Ship with confidence
Architecture, performance, crash monitoring and App Store constraints are considered throughout the work so the app remains stable after launch.
