Mobile app modernization

Bring Your App Up to Date Without Slowing Down Releases

We've been building React Native apps since the framework's early days, and we've seen technologies, architectures, and engineering practices evolve along the way. If you're dealing with technical debt or want to upgrade your app, we can help you modernize it without disrupting your release cycle.

We've seen every era of React Native, and we know why things changed

13+ years

of building custom software

400+

engineers, designers, and QA specialists on board

React Foundation

founding members, alongside Meta, Microsoft, or Expo

30+ core libraries migrated

to the New Architecture

Some of our engineers have been working with React Native since its early days. We've seen the ecosystem evolve, so we understand not just what changed, but why it changed. We know what still works well, what has reached the limits, and how to replace outdated solutions without introducing unnecessary risk.

We also know that production software is never built from a blank slate – every app reflects numerous business and technical decisions. That's why we don't recommend rewrites when they aren't needed. Most of the time, we help teams modernize incrementally, keeping what still works and improving what doesn't, while making sure they can ship without disruption throughout the process.

SeaPeople is a social platform for boaters built with React Native. In just over three months, we modernized the app's foundations, improved its crash-free rate to nearly 99%, and introduced new social features that gave the team a solid platform for future development.
