The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Funding the same feature twice
Separate iOS and Android teams double the cost of every feature.
- 02
Platforms out of step
Features reach one platform weeks before the other.
- 03
Concerns about native quality
Stakeholders worry a cross-platform app will feel slow or unfamiliar to users.
Overview
Cross-Platform Mobile (Flutter & React Native) at VulcanTech
Cross-platform app development builds iOS and Android applications from a single shared codebase, using frameworks such as Flutter and React Native. VulcanTech delivers cross-platform mobile experiences with one codebase, one team and synchronised releases on both platforms. Native modules cover features that need platform-specific code, and we recommend native development instead where the product's requirements make cross-platform the wrong trade-off.
Key deliverables
- Single codebase for iOS and Android
- Native modules where required
- Synchronised store releases on both platforms
- Automated test suite
- Build and release pipeline

Our process
How we deliver
A delivery process you can see into — from first workshop to production support.
- 01
Discovery
A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.
- 02
Architecture & planning
We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.
- 03
Iterative delivery
Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.
- 04
Assurance & hardening
Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.
- 05
Launch & continuity
We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.
Engagement models
Work with us the way that suits you

Best for: Long-term product development and evolving roadmaps
Team extension
