Cross-platform
app development
in Seattle

The cost depends on feature complexity, the number of screens, backend infrastructure requirements, and the depth of device integration needed. Cross-platform development reduces cost compared to building separate native iOS and Android apps, but the savings vary based on how much platform-specific behavior the app requires. A straightforward cross-platform booking or service app for a Seattle professional services firm differs significantly from a field operations tool for an aerospace contractor in the Boeing supply chain that requires device-specific hardware access, secure offline sync, and compatibility with ruggedized Android devices used across Puget Sound operations. We define pricing after reviewing your product brief and technical requirements.

A standard cross-platform app covering core screens, basic backend integration, and standard device features typically takes 2 to 4 months from specification through launch. Projects with complex offline requirements, real-time data, or specialized hardware integration — relevant for Seattle's healthcare IT, maritime operations, and supply chain sectors — generally run from 4 to 8 months. We set a clear delivery schedule at kickoff with working builds delivered throughout development so your team can test on actual iOS and Android devices before launch.

We work primarily with React Native and Flutter, selecting the framework based on your project's specific requirements. React Native is well-suited for apps with complex JavaScript logic or when integrating with an existing web platform — common for Seattle SaaS companies building mobile extensions of browser-based tools. Flutter delivers high-performance, visually consistent experiences across both platforms, which works well for consumer apps and tools where the interface needs to feel native and polished on every device. We recommend based on your codebase, team, and long-term maintenance needs.

Cross-platform development uses a single shared codebase that compiles to both iOS and Android, reducing development time and cost while maintaining access to most device features. Native development produces platform-specific apps that access the full range of hardware capabilities and follow each platform's design conventions exactly. For most Seattle business apps — client portals, service tools, field operations software, and customer-facing booking or ordering apps — cross-platform development delivers full-quality results at lower cost. Native development makes sense when the app requires features unavailable or unreliable in cross-platform frameworks, or when the app competes directly in a crowded consumer market where platform-native feel is a competitive differentiator.

Yes — modern cross-platform frameworks deliver performance that meets the requirements of most business applications, including those used by Seattle's technology, healthcare, and enterprise sectors. React Native and Flutter both compile to native code, not a web view, which means the performance gap between cross-platform and native has narrowed significantly. For applications requiring computationally intensive operations, direct GPU access, or very low-level hardware control — uncommon in most business software — native development remains the better choice. We assess performance requirements during discovery and recommend the right approach before any code is written.

We start with a discovery phase that defines users, core use cases, platform requirements, and integration points. From there we produce a functional specification and design system before beginning development. Builds are delivered iteratively throughout the project so your team can test on real iOS and Android devices as features are completed — not just at the end. Before launch we complete a thorough quality pass covering performance, edge cases, and device compatibility across the full range of hardware your Seattle users are likely to carry.

We manage the full submission process for both the Apple App Store and Google Play, including account setup guidance if needed, compliance review, metadata preparation, and responding to review feedback from Apple or Google. For Seattle businesses launching a first app, we walk through the requirements and timelines at the outset so the submission process does not become a surprise at the end of development. For clients with existing accounts, we coordinate directly with your team to ensure credentials and publishing rights are in place well before the launch date.

We offer structured post-launch support covering bug fixes, OS update compatibility testing, performance monitoring, and feature development as your requirements grow. For Seattle businesses operating in fast-moving sectors — healthcare IT, logistics, and enterprise software — apps typically require ongoing updates as operating systems evolve and as new requirements emerge from users in the field. We offer retainer arrangements that keep a consistent team available for your product rather than requiring you to re-engage from scratch each time a change is needed.
