AI Service

Mobile App Development

iOS and Android apps with AI features built in from day one. React Native cross-platform development — one codebase, two stores, full AI capability.

What We Build

AI-Native Mobile Apps

Every app we build is AI-ready from the ground up — not retrofitted after launch.

Cross-Platform (iOS & Android)

React Native apps that run natively on both platforms from one codebase — faster to build, cheaper to maintain.

AI Features Built In

Chatbots, voice commands, smart search, recommendations, image recognition — AI from day one, not bolted on later.

Secure & Scalable Backend

Node.js or Laravel APIs, user authentication, push notifications, real-time data, and cloud hosting on AWS or GCP.

App Store Launch

Full submission to Apple App Store and Google Play — including screenshots, descriptions, and App Store Optimisation.

FAQ

Frequently Asked Questions

Do you build for iOS and Android?

Yes. We primarily use React Native for cross-platform development, which delivers native performance on both iOS and Android from a single codebase. For highly performance-critical apps, we also build in Swift (iOS) or Kotlin (Android).

Can you add AI features to a mobile app?

Yes — AI is our speciality. We can add chatbots, voice assistants, image recognition, smart search, personalisation engines, and AI-powered recommendations to any mobile app.

Do you handle App Store and Google Play submission?

Yes. We handle the full submission process including screenshots, descriptions, ASO (App Store Optimisation), and compliance checks. We also manage app signing and provisioning profiles.

How long does a mobile app take to build?

A simple app (3–5 screens, core functionality) takes 4–8 weeks. A full-featured app with backend, user accounts, and AI features typically takes 8–16 weeks. We provide a detailed timeline after scoping.

Do you provide ongoing maintenance?

Yes. We offer monthly maintenance packages covering OS updates, bug fixes, performance monitoring, security patches, and feature additions.

Can you work with a design we already have?

Absolutely. If you have Figma designs or brand guidelines, we build to spec. If you need design work, our team covers UI/UX design as part of the project.
