Mobile Apps

Native and cross-platform mobile apps built for reliability at scale.

We design and build iOS and Android applications using React Native, and native Swift or Kotlin when performance demands it — apps built to survive bad networks, old devices, and app-store review.

What we deliver

  • iOS and Android apps from one React Native codebase, with native modules where they earn their keep
  • Offline-first data sync so the app works on the subway, not just in the demo
  • Push notification infrastructure with segmentation and quiet-hours handling
  • Crash reporting, analytics, and phased rollouts configured before the first release
  • App Store and Play Store submission handled end to end, including review-rejection triage

How the engagement runs

We prototype the two or three screens that carry your app's core loop first and put them on real devices in week two. Every release after that goes through device-lab testing across screen sizes, OS versions, and throttled network conditions before your users ever see it. Phased rollouts mean a bad build reaches 5 percent of users, not all of them.

Where this fits

Teams usually come to us with a web product that needs a real mobile presence, an agency-built app that has stopped scaling, or a native codebase their last mobile engineer took with them.

Outcomes you can expect

  • A first TestFlight or internal-track build within three weeks
  • Crash-free session rates above 99.5 percent as a standing bar
  • Rollbacks that take one click because releases are phased by default
  • One codebase your web engineers can contribute to
