app development
Backed by more than five years of implementation experience, we support React Native and Expo projects from new development to renewal, operation, and improvement.
01 / Services
What we do
We support each phase of iOS and Android app development with React Native and Expo. Our involvement can be adjusted to match the state of your project.
Renewal of existing apps
We support staged renewal of existing apps, including migration from native codebases to React Native.
- Current-state analysis and migration planning
- Migration from native to React Native
- UI / UX renewal
Operation and improvement
After release, we continue supporting improvement work, feature additions, and OS updates so the app can keep delivering value.
- React Native / Expo updates
- Migration to the New Architecture
- Build automation and performance improvement
- Feature additions and refactoring
React Native technical support
We provide focused support for development issues and environment problems. Short, targeted consultations are also possible.
- Build error investigation
- Library integration support
- Widget development
- Development environment setup
Setup support for AI-assisted app development
We help clients build the initial environment and operating rules needed to continue app development with AI effectively.
- Selection and setup of AI coding tools
- Project-specific rule file setup
- MCP server and automation setup
- Team onboarding for day-to-day usage
- Operational documentation for self-sufficiency
02 / Strengths
How we work
Focused on apps and React Native
In many development firms, mobile apps are only one part of a broad portfolio of client services. High-quality apps at meaningful scale require app-specific experience, and that is where we stay focused.
Looking beyond simply shipping
AI has lowered the barrier to releasing apps, but most products still disappear without being used. We care about what makes an app worth using, not only what gets it shipped.
Code built for handover
Apps continue evolving after release. We prepare maintainable codebases and build workflows so later improvement work and team handovers can happen smoothly.
User perspective matters
To build products used by many people, development needs more than the builder's own viewpoint. Experience from running our own app Simpluna informs how we design around real users.
Responding to real needs
We do not simply implement requests as written. We look at the goal behind the request and work through practical options, including alternatives when technical constraints exist.
03 / Process
Process
From the first conversation through release and ongoing operations, we adapt the process to the scale and shape of the project.
Consultation / discovery
We discuss what you want to build and what challenges you are facing. A rough starting point is enough.
Planning / estimate
We organize the requirements and propose a timeline, team structure, and budget range. Prototyping is included when needed.
Design / implementation
After aligning on the design direction, we move into implementation and share progress regularly.
Release
We support store submission and public release, including the operational know-how around that process.
Operations / improvement
We continue with maintenance and improvement after launch. Long-term support is often the most important phase.

05 / FAQ
FAQ
These are common questions we receive before React Native and Expo projects begin.
What parts of a React Native project can you cover?
We support a wide range of work, from new app development to redesign, operational improvements, and store submission. We can also join at the planning or requirements-definition stage.
Can you support app development with Expo?
Yes. We generally recommend Expo because of its development speed and operational advantages. We can also support setups involving EAS Build, Development Build, and native integrations.
Can we discuss migrating an existing native app to React Native?
Yes. After reviewing the current codebase and operational situation, we can propose either a full migration or a staged migration plan.
Does Expo still limit native functionality?
Older managed workflows had clear restrictions, but modern Expo setups allow much more control over native configuration. Most product requirements can now be handled.
Should we worry about React Native performance?
React Native has improved steadily, and for most general app use cases performance is rarely the bottleneck. When needed, we also handle performance measurement and optimization.
Can you handle maintenance after release?
Yes. We can support OS updates, React Native and Expo upgrades, feature additions, and performance improvements as ongoing work.
How does the estimate process work?
Please send an overview through the estimate form. After reviewing the content and asking any follow-up questions if needed, we will provide an estimate later.
