Mobile Apps

iOS and Android apps from one product core

Cross-platform apps that feel native, share a backend with your web product, and ship to both app stores from a single codebase.

Overview

Mobile App Development

A mobile app is rarely a product on its own — it is the most convenient front door to a product that also has a web app, an admin system and an API behind it. We build apps that way: one product core with a mobile experience designed for the moments where a phone is the right tool, rather than a second, disconnected codebase to maintain.

We use cross-platform technology (React Native and Expo) so a single codebase ships to iOS and Android with a native look and feel, native performance where it matters, and access to device features like camera, location, biometrics and push notifications. For most businesses that halves the cost and time compared with two separate native apps, without a compromise users notice.

From app-store accounts and review guidelines to offline behaviour, deep links and analytics, we handle the details that turn a working build into an app people install and keep.

What you get

Delivered as one complete product

Everything a production-grade product needs, built by the same senior team from start to finish.

Cross-platform iOS & Android apps

One TypeScript codebase, native components, and a shared design system so both platforms stay in step.

Offline-first & real-time sync

Apps that work with a poor signal and synchronise cleanly when it returns — essential for field staff, events and travel.

Payments, push & deep links

In-app purchases or Stripe checkout, rich push notifications, and links that open the right screen from email or the web.

Shared backend & API

A single API serving mobile, web and admin, so features and data stay consistent everywhere.

App-store launch

Accounts, listings, screenshots, review compliance and phased rollouts handled with you, not left as homework.

Analytics & crash reporting

Usage analytics, crash monitoring and over-the-air updates so you can fix and improve without waiting on store review.

How we work

From first call to live product

  1. 01

    Define the mobile moments

    Which jobs genuinely need a phone in hand? We scope the app around those rather than cloning the whole web product.

  2. 02

    Design for thumbs

    Prototypes tested on real devices — navigation, gestures, forms and offline states — before we build.

  3. 03

    Build and test on devices

    Two-week sprints with TestFlight and Play internal builds so you are using the real app throughout.

  4. 04

    Launch and update

    Store submission, staged rollout, and over-the-air updates for fast iteration after launch.

Where this fits

Typical projects

Companion app for a web platform

Give customers of your SaaS or marketplace a native mobile experience for the tasks they do on the move.

Field and operations apps

Inspections, deliveries, site visits and check-ins with offline capture, photos, signatures and location.

Consumer apps with payments

Booking, ticketing, membership and loyalty apps with secure checkout and push-driven engagement.

Why InteleForge

What makes the difference

One team for app, web and backend

No integration gap between a mobile agency and a web agency — the same engineers build and own the whole product.

Cross-platform without the compromise

We know where cross-platform shines and where native modules are needed, and we make that call feature by feature.

Launch handled end to end

App-store setup, review rules, privacy manifests and phased rollouts are part of the job, not an extra.

FAQ

Mobile Apps: your questions

Straight answers on cost, timing and how we work.

A first release of a cross-platform app with a backend, accounts, one core workflow and push notifications typically costs £20k to £70k. Because one codebase serves both iOS and Android, that is far less than two native builds.
