Mobile App Development Services from Global One Digital ship native iOS, Android and cross-platform mobile applications for B2B and SaaS teams across the USA, EU and CIS. We deliver MVPs that need to validate quickly and production-grade apps that already serve thousands of users — selecting the right approach based on your business goals, not on which framework we like writing this quarter.
For most B2B and SaaS apps, React Native or Flutter ships faster than native and feels indistinguishable to the user, with one codebase for both Apple and Android. For consumer apps with heavy graphics, ARKit work, or hardware integration, native Swift and Kotlin remain the right call. For internal tools and content-heavy apps, a Progressive Web App often delivers better return on investment without App Store overhead.
Standard scope includes product discovery and feature scoping, custom UX and UI design, native or cross-platform implementation by senior engineers, REST or GraphQL backend integration, push notifications and deep linking, analytics and crash monitoring (Firebase or Sentry), App Store and Play Store submission, plus optional retainer for OS updates and ongoing maintenance.
Our quality bar covers offline-first architecture where it matters, performance tuning for mid-range devices (not just flagships), accessibility from the design phase, and proper error handling that survives flaky mobile networks. We use cloud backends (AWS, Google Cloud, Firebase) for storage, sync and push infrastructure when building from scratch.
An MVP single-platform app ships in six to eight weeks. A production cross-platform app on React Native or Flutter takes ten to fourteen weeks. Native iOS and Android with custom modules requires sixteen weeks or more. Discovery call narrows the estimate to your specific scope within a few business days.
We frequently embed into existing engineering teams, work in your repository and follow your code review process. Our approach is documented and handed off cleanly — your developers can extend the application a year later without playing archaeologist. For teams without in-house mobile experience, we also offer ongoing maintenance retainers covering OS updates, crash monitoring and security patches.
For most B2B and SaaS apps, React Native or Flutter ships faster and costs less while feeling indistinguishable from native to users. For consumer apps with heavy graphics, ARKit or hardware integration, native Swift/Kotlin is the right call.
MVP single-platform: 6-8 weeks. Production cross-platform: 10-14 weeks. Native iOS + Android with custom modules: 16+ weeks.
Yes. We submit on your developer accounts, handle review feedback, set up TestFlight and Play Console internal testing tracks, and configure release pipelines.
Maintenance retainers cover OS update support (iOS/Android), crash monitoring, performance tuning and security patches. Typically $1.2-4K/month depending on app complexity.
Yes. We work with REST and GraphQL APIs, handle authentication (JWT, OAuth), and design caching and offline-sync strategies that match your backend constraints.
