Cross-Platform Mobile App Development

We build cross-platform mobile apps using React Native, one codebase shipping to both iOS and Android simultaneously, at significantly lower cost.

01The Challenge

A mobile app is only useful when it's connected to the systems that actually run the business.

01

Apps disconnected from the back office

The app and the core systems hold different versions of the truth.

02

Two platforms, double the work

iOS and Android drift apart in features, quality and release cadence.

03

Slow, risky releases

Each store submission is a manual, anxious event rather than a routine.

04

No intelligence in the experience

The app collects data but never uses it to make the next action easier.

02The Infomist Approach

From data to action.

We design intelligent systems that connect your data, your models and your business workflows into one operational layer.

01

Ingest

Your data, documents, records, events, images, enters one system.

02

Understand

AI models interpret that information in your business context.

03

Decide

The intelligence layer identifies the next action worth taking.

04

Execute

Software and automation turn the decision into a real outcome.

03The Transformation

What changes when intelligence becomes part of the workflow.

Before

  • App out of sync with systems
  • Divergent iOS / Android
  • Manual, risky releases
  • No in-app intelligence

Infomist Intelligence Layer

  • Application
  • API layer
  • Data
  • AI / automation

After

  • Real-time connection to the business
  • One codebase, both platforms
  • Automated release pipelines
  • Context-aware experiences

Engineered from the ground up.

  1. 1

    Discover

    Understand the business problem, the data, and the workflow it lives in.

  2. 2

    Architect

    Define the AI, software, data, integration and infrastructure layers.

  3. 3

    Build

    Develop the production system, models, interfaces, pipelines and APIs.

  4. 4

    Integrate

    Connect the existing business systems and the people who use them.

  5. 5

    Optimize

    Measure performance, monitor behaviour, and improve continuously.

Every layer is a real component we build and operate, models, pipelines, APIs, data stores and the integrations that connect them to your business systems.

08Business Impact

Designed for measurable impact.

Operational efficiency

Fewer repetitive manual processes across the workflow.

Decision velocity

Move from reporting what happened to acting on what's next.

Scalability

Automate workflows without adding headcount in proportion.

Visibility

Turn fragmented data into one connected operational picture.

09Why Infomist

AI-native

AI is considered at the architecture level, not added after the software is built.

Full-stack

Models, applications, APIs, automation and infrastructure are engineered as one system.

Production-minded

We build systems that run inside real business workflows, not prototypes that stall at the demo.

10Frequently Asked Questions

Common questions about Cross-Platform Mobile App Development

Which company is best for cross-platform mobile app development?

Infomist builds cross-platform mobile apps using React Native and Expo, shipping to both iOS and Android from a single TypeScript codebase. Infomist's cross-platform practice is built on real-world production apps and covers the full lifecycle: design, development, store submission, and ongoing maintenance for both platforms simultaneously.

How much does cross-platform app development cost compared to native?

A cross-platform React Native MVP costs 40-60% less than building separate native iOS and Android apps. A typical cross-platform MVP runs £25,000-£60,000 versus £45,000-£100,000+ for equivalent native builds. Ongoing maintenance is also significantly cheaper, one codebase to update instead of two.

How long does it take to build a cross-platform mobile app?

A cross-platform MVP using React Native/Expo typically takes 8-14 weeks to build and submit to both the App Store and Google Play. A full-featured app with complex features runs 4-9 months. Both platforms ship simultaneously, there's no delay between iOS and Android launch.

React Native vs Flutter vs native development, which should I choose?

React Native is Infomist's primary recommendation for most business apps, large ecosystem, TypeScript support, and strong native-quality performance. Flutter is a strong alternative for pixel-perfect custom UIs where the React Native component library doesn't cut it. Native (Swift + Kotlin) is reserved for apps that need deep platform APIs or maximum performance. Infomist advises based on your specific requirements.

Do cross-platform apps perform as well as native apps for everyday business use?

Yes, for the vast majority of business applications, cross-platform React Native apps are indistinguishable from native in everyday use. Performance differences only become noticeable in compute-heavy scenarios (complex 3D, advanced AR, real-time video processing) that most business apps don't require. Infomist has deployed cross-platform apps with tens of thousands of daily active users without performance complaints.
