Mobile

Build, modernise and run your iOS and Android apps

An app is not just a project, it's a platform to keep alive. At Wide x TALAN, we design mobile and phygital apps, cross-platform or AI-boosted native, we take over and migrate apps built on end-of-life technologies, and we manage their presence on the stores, from release to analytics. Apps that are high-performing, accessible, compliant (FADP, App Store & Play Store guidelines) and integrated with your IS.

The mobile site is no longer enough, the app takes over, and has to last

Your users, customers, citizens, employees or field technicians, expect fast, reliable apps that are useful every day. That means choosing the right foundation, keeping quality high, moving off ageing technologies and staying visible on the stores, release after release, on iOS as well as Android.

  • A single iOS + Android codebase (Flutter) for controlled TCO, or Swift and Kotlin native when performance or hardware access demands it.

  • Code review, continuously generated tests, detection of regressions and vulnerabilities: our developers deliver faster, without lowering the bar.

  • Cordova, Ionic, Xamarin: secure and maintain what exists, then migrate step by step, without losing your users or your reviews.

  • Releases, CI/CD, crash and review monitoring, optimised listings (ASO) and analytics: your app stays up to date and visible.

  • Push notifications, onboarding, personalisation, NFC, QR, offline mode: turning the download into lasting usage, in-store and on the move.

  • Privacy by design (FADP, GDPR), App Store & Play Store guidelines, inclusive apps (WCAG) that are light on energy and data.

One mobile approach, built for your context

Usage, expected performance, field constraints: we adapt the mobile architecture to your reality, from cross-platform to high-performance native to phygital. And once the app is delivered, we manage its life on the stores.

Multi-platform

TCO & time-to-market

The efficient mobile app that lowers TCO, accelerates delivery and covers iOS + Android with a single codebase.

Want a premium app on both stores, without doubling teams or budgets? Cross-platform frameworks (Flutter) now offer near-native maturity: you cut TCO by 30 to 40%, speed up time-to-market and simplify maintenance, with a premium UX through co-design and AI built in from the scoping phase. Where your usage demands it, we can also push toward high-performance native or phygital (PWA, offline mode) on the specific points that matter.

  • Banking / insurance apps
  • Citizen portals
  • Retail & loyalty apps
  • Field & industry apps

AI-boosted native

Performance & quality

High-performance native, without the extra cost: our iOS and Android developers work with an AI that locks in quality at every step.

Some uses demand native: performance, deep hardware access (sensors, camera, Bluetooth), security, tight integration with iOS and Android. Our Swift/SwiftUI and Kotlin/Jetpack Compose developers are supported by an AI built into their daily work: code generation and review against our standards, automated tests produced continuously, detection of regressions, vulnerabilities and accessibility issues before every release. You get two top-tier native apps, delivered faster, with a controlled and consistent level of quality, without doubling budgets.

  • Swift / SwiftUI
  • Kotlin / Jetpack Compose
  • AI code review
  • Automated testing

Legacy app migration

Security & longevity

Is your app built on end-of-life technology? We secure it, maintain it, then migrate it to a modern foundation, with no disruption for your users.

Cordova, PhoneGap, Ionic 1 to 3, Xamarin, Titanium, old React Native versions, ageing Objective-C or Java: these technologies no longer keep up with store requirements or new iOS and Android versions, and keep piling up vulnerabilities. We start by auditing and securing what exists (dependencies, plugins, data, updates required by the stores) and maintain it to keep the app live. Then we migrate it step by step, to Flutter or native, carrying over features, data and user accounts, without losing your ratings or reviews on the stores.

  • Audit & hardening
  • Legacy maintenance
  • Step-by-step migration
  • Data and account takeover

App store management

Publishing & visibility

Your apps live, up to date and visible on the App Store and Google Play, without your teams having to worry about it.

Publishing an app doesn't end with the first submission. We take charge of your App Store and Google Play accounts: releases and updates, guideline compliance and rejection handling, CI/CD pipelines that automate builds, signing and deployments (TestFlight, internal testing), and continuous quality monitoring (automated tests, crash reports, ratings and reviews). On the visibility side, we produce the marketing content for your store listings (copy, screenshots, videos, ASO) and track download, conversion and retention statistics to improve your app, release after release.

  • Releases & updates
  • Mobile CI/CD
  • Quality, crashes & reviews
  • ASO & analytics

Every app,
augmented by AI and data

AI is not an extra gadget: we build it into the heart of the app to personalize journeys, smooth out usage and fuel engagement, from first launch to loyalty.

  • Contextual help, search and conversational support embedded, multilingual and under control.

  • Smart push, key moments and personalized re-engagement based on profile and usage.

  • Content and journeys adapted to context, location and each user's behavior.

  • Mobile
  • Cross-platform

An app that works is not a tech choice, it's an architecture of usage: we align performance, data and journeys around a single goal, real adoption by the user.
