Mobile app development
iOS and Android apps from first design to App Store and Play Store release, usually from one shared codebase.
Good fit if
- Companies whose customers or field staff need an app, not a website
- Startups launching a mobile-first product
- Teams with an existing app that crashes, lags or has stalled
What we do
- App design
- Screens and interactions designed for thumbs and small screens, following iOS and Android conventions.
- Cross-platform build
- One React Native or Flutter codebase for both platforms, with native modules where performance or hardware access needs them.
- Backend and offline support
- APIs, push notifications, and sync that keeps working when the signal doesn’t.
- Store release
- Builds, signing, store listings and review submissions handled for you.
How it runs

Questions
Native or cross-platform?
Cross-platform suits most business apps and roughly halves the cost of supporting two platforms. We recommend native when the app depends on heavy graphics or deep hardware access.
Do you handle App Store rejections?
Yes. Submission and any back-and-forth with review is part of the work.
Often combined with
- Web applications Customer portals, internal tools, dashboards and SaaS products, built to be fast, accessible and easy for the next developer to work on.
- Cloud and DevOps Secure, reproducible infrastructure on AWS, Google Cloud or Azure, with deployments your team can run on a Friday afternoon without worrying.
- Custom tools and integrations The internal tools, integrations and automations that don’t fit a product box, built quickly and maintained properly.
