Do you build for both iOS and Android?

Yes. We build cross-platform apps using React Native and Flutter so your app works on both iOS and Android without needing two separate builds and two separate budgets.

How long does it take to build a mobile app?

A focused MVP typically takes 8 to 12 weeks. A full-featured consumer or business app is usually 3 to 6 months depending on complexity. We give you a clear timeline before anything starts.

Can the app connect to our existing Odoo or CRM system?

Yes. We build custom API integrations that connect your app to Odoo, your CRM, your payment gateway, and any other platform your business already uses.

Do we own the app after it's built?

Yes. Full source code and full intellectual property rights belong to you. You are never locked into a licence or dependent on us to keep the app running.

Can you update and maintain an app we already have?

Yes. We work with existing apps regularly. Whether it needs a full redesign, new features, or just maintenance to keep it compatible with the latest iOS and Android updates, we can take it on.

Commercial Architecture

Engineered for Operational Workflows, Not Consumer Speculation

Consumer apps have a 99% failure rate. We don’t build games or speculative social networks. We engineer mission-critical mobile applications that empower field teams, streamline customer bookings, and sync real-time data back to your central office.

Core B2B Mobile Engineering Capabilities

Cross-Platform Single Codebase

One production codebase in React Native or Flutter deploying natively to Apple iOS and Google Android, cutting build and maintenance overhead by 50%.

Offline-First Data Architecture

Field teams can inspect assets, scan barcodes, and capture signatures without internet; data syncs automatically with zero data loss upon reconnecting.

Hardware & Sensor Integration

Native camera barcode scanning, GPS geolocation tracking, Bluetooth thermal printer pairing, and biometric fingerprint/FaceID authentication.

Enterprise ERP & Cloud Sync

Direct, secure synchronization with your central SQL database, Odoo ERP, Salesforce, or custom cloud backend with strict access controls.

The 4 Costly Mobile App Traps We Eliminate

Why standard software agency and template approaches fall short.

01. The "Double Native" Expense

Paying two separate development teams to build Swift for iOS and Kotlin for Android when modern cross-platform engines deliver identical 60fps performance.

02. Off-the-Shelf App Builder Fragility

No-code app builders that crash under real-world usage, fail offline, and permanently trap your data on proprietary third-party platforms.

03. App Store Rejection Delays

Navigating Apple App Store and Google Play compliance guidelines rigorously from day one so your commercial rollout is never blocked.

04. Unmaintainable Freelancer Code

Fragile spaghetti code without documentation that breaks completely the moment Apple or Google releases an operating system update.

Commercial Qualification: Is This the Right Fit for Your Business?

✓ Who Our Services Are Designed For

Established UK businesses, logistics providers, clinic networks, and field service organizations (£1M+ turnover).
Companies requiring proprietary mobile tools for staff dispatch, asset inspection, or customer self-service.
Projects with defined operational workflows, clear security standards, and measurable commercial ROI.

✕ Who We Are NOT Designed For

"App idea" dreamers with £500 budgets seeking free co-founder equity work.
Consumer gaming, meme apps, or speculative social media clones.
Businesses that only need a mobile-responsive website (we will recommend Webflow or Next.js instead).

HOW IT WORKS

Built to Perform on Every Device, Every Time.

FFour things that make our mobile apps the right choice for businesses that need more than a basic build.

Native and Cross-Platform Development

We build for iOS and Android using React Native and Flutter. One codebase, two platforms, no compromise on performance or user experience.

Backend Built to Handle Real Traffic

Your app needs infrastructure that doesn't fall over when usage spikes. We build scalable backends that keep your app fast and stable whether you have 100 users or 100,000.

Connects to Your Existing Systems

Your app talks to your CRM, your Odoo system, your payment gateway, and any other platform your business runs on. No data silos, no manual syncing.

App Store Ready and Secure

We handle the full submission process for both the Apple App Store and Google Play. Security, compliance, and performance standards met before anything goes live.

Our Services

What We Build for Your Business.

Six types of mobile applications. Each one built around your specific requirements.

Customer-Facing Mobile App

Give your customers a dedicated app to browse, book, order, or engage with your business. Branded, fast, and built to keep them coming back.

Internal Team Apps

Field teams, remote staff, and warehouse workers need tools that work on the go. We build internal apps that replace paper processes and disconnected spreadsheets.

On-Demand and Booking Apps

Appointments, deliveries, service requests. We build on-demand apps with real-time availability, push notifications, and payment built in from the start.

eCommerce Mobile Apps

A dedicated shopping app converts better than a mobile website. We build app-first ecommerce experiences with smooth product browsing, fast checkout, and order tracking.

MVP App Development

Test your idea before committing to a full build. We develop a focused MVP with your core features so you can get real user feedback and validate the product before scaling.

App Maintenance and Upgrades

Already have an app that needs fixing or updating? We audit, improve, and maintain existing mobile applications so they stay fast, secure, and compatible with the latest OS updates.

The Mobile App Advantage

Why Businesses Invest in a Dedicated Mobile App.

What you actually get when you stop relying on a mobile website to do a job it was never designed for.

Direct access to your customers

Push notifications, home screen presence, and instant load times. A mobile app puts your business one tap away at any time, without competing with a browser full of other tabs.

Better experience than a mobile website

Mobile websites are compromises. Apps are built specifically for small screens, touch interactions, and offline use. Users notice the difference immediately and stay longer because of it.

Faster performance under real conditions

Apps load faster, run smoother, and handle poor connectivity better than any website. For businesses where the user experience directly affects revenue, that performance gap matters.

Grows with your user base

We build on scalable infrastructure from day one. As your downloads and active users grow, the app keeps up without needing a complete rebuild or emergency fix at the worst possible moment.

Challenges

Why Most Mobile Apps Fail to Deliver.

It's rarely the idea that's the problem. It's usually one of these four.

Learn More

Built for the Demo, Not for Daily Use

A lot of apps look great in a presentation and fall apart when real users start tapping around. Poor testing, rushed development, and no real user research behind the build.

No Connection to the Rest of the Business

An app that doesn't talk to your CRM, your booking system, or your operations platform creates more work, not less. Data has to be entered twice and nothing stays in sync.

Abandoned After Launch

Most apps need ongoing updates for new OS versions, new devices, and new user expectations. Businesses that treat the launch as the finish line end up with a broken app and bad reviews within six months.

Built Once, Impossible to Change

Rigid codebases that can't be updated without a full rebuild. We build modular apps that can be updated, expanded, and improved as your business and your users evolve.

Native Performance

High-Performance Apps vs Cheap App Builders

In the mobile space, user experience is everything. Users will abandon an app immediately if it feels sluggish, drains their battery, or crashes. Many development agencies use cheap "app builders" or basic WebView wrappers to quickly push a website into an app store, resulting in a terrible user experience.

ExoGrow develops high-performance Native and advanced Cross-Platform applications. We ensure fluid 60fps animations, robust offline capabilities, and seamless hardware integration (camera, GPS, biometrics). We build apps that users actually want to keep on their home screen.

Feature / Capability	ExoGrow Mobile Engineering	Generic App Builders
Performance	✓ Fluid 60fps Native Performance	Sluggish WebView wrappers
Hardware Access	✓ Deep API integration (Camera, GPS, etc.)	Limited or buggy hardware access
Offline Capabilities	✓ Robust offline sync and storage	Fails immediately without internet
App Store Success	✓ Full App Store Optimization (ASO)	Often rejected by Apple/Google
