Mobile App Development

Mobile apps people keep on their home screen.

// Overview

A good app feels obvious: it opens fast, works on a patchy connection and does one job really well. We design and build iOS and Android apps — usually cross-platform to save you time and budget — and take care of the app-store launch and updates that follow.

// What we deliver

Everything included in Mobile Apps.

01

Cross-platform apps

One codebase for iOS and Android with Flutter or React Native, without compromising feel.

02

Native iOS & Android

Swift and Kotlin when you need deep device features or maximum performance.

03

Backend & APIs

Secure APIs, authentication, push notifications and admin panels to run the app.

04

Offline & real-time

Local storage and sync for spotty networks; live updates for chat, tracking and orders.

05

App store launch

Store listings, screenshots, review guidelines and release management handled for you.

06

Maintenance & upgrades

OS updates, crash monitoring and new features after launch.

// Why Nextgen

Designed for real phones and real networks

We test on budget Android devices and slow connections, not just the latest iPhone — because that’s where most of your users are.

  • Tested on low-end devices
  • Crash and analytics monitoring
  • Store submission handled

    Interactive prototypes tested with real users before development starts.

  3. 3

    Build & test

    Sprint-based development with internal test builds you can install every two weeks.

Questions about Mobile Apps

For most business apps, Flutter or React Native gives you both platforms for close to the cost of one. We recommend native only when a feature genuinely needs it.
