Mobile App Development
Seven ways to put your app in someone's pocket
One team, one invoice. Start with the platform your app needs today, and add UI/UX, backend or maintenance the moment you're ready for it.
iOS App Development
Swift and SwiftUI apps built for the platform, not adapted to it. Smooth animations, Apple's guidelines respected from the first sprint, and a review process we manage so launch day doesn't slip.
Android App Development
Kotlin apps built to run cleanly across the fragmented world of Android devices and OS versions, tuned for performance and shipped straight to Google Play.
React Native Apps
One React Native codebase, two live app stores.
Flutter Apps
A single Flutter codebase renders pixel-identical, high-performance interfaces on iOS and Android alike, so your design ships exactly as you approved it, everywhere..
Enterprise Mobile Apps
Workforce and customer apps built for scale: SSO, offline-first sync and deep integration with the ERPs, CRMs and internal systems your business already runs on.
App Maintenance
OS-update readiness, crash monitoring, fast fixes and new features, so your app stays live, fast and five-star long after the launch-day excitement fades.
What we deliver
Full-lifecycle app development, nothing outsourced
Design, backend, native and cross-platform builds, real-device QA, store submission and maintenance all live in-house at WebNX Global Services. We do not hand your design to one agency and your build to another. One team owns your app from first sketch to live release to version two, and you get a single point of contact the entire way.

How we work
Our mobile app development process
Seven stages, each with something real for you to review and approve before the next one starts. No black box between your idea and the app store.
- 01
Discovery
We map your users, business goals, target platforms and technical constraints before recommending an approach, not before.
- 02
Design
Wireframes evolve into a polished, tested UI, reviewed and signed off by you before a single line of app code gets written.
- 03
Architecture
Platform choice, backend design, data model and integration plan documented and agreed before development starts.
- 04
Development
Clean, native-quality code built in reviewable sprints, with AI-assisted tooling speeding up routine work and a build you can try every week.
- 05
Testing
Real iOS and Android devices, not just simulators, plus performance, security and accessibility checks before anything ships.
- 06
Launch
We prepare store listings, handle App Store and Play submission, manage any review pushback and monitor the release closely.
- 07
Support
Monitoring, OS-update readiness, fixes and new features long after launch day. We don't disappear once the app is live.
Why choose us
The Team That Stays Past Launch Day
Most shops build the app and disappear the day it ships. We design it, build it, get it through store review and keep it alive as iOS and Android keep changing underneath it. We push back on scope that will not earn its keep, and we stay reachable long after launch, the way we have since 2008.
Talk to us-
Idea to store, one team
Design, build, test, submit and maintain. One accountable team owns the entire journey, not just the coding sprint in the middle.
-
Native or cross-platform, your call
Swift, Kotlin, React Native or Flutter. We recommend the approach that fits your budget, timeline and performance needs, not the one we happen to prefer.
-
AI-driven speed, human-reviewed quality
AI-assisted tooling gets your build moving faster, and every screen still passes through experienced engineers before it reaches a device.
-
Design that earns the rating
App store ratings are won on experience, not feature counts. Research-led UX and genuine polish are part of every build, not an upsell.
-
Tested on real devices
We test on actual phones and tablets across OS versions, not just simulators, before anything reaches review.
-
We own store submission
App Store and Play review can be a maze of rejections. We prepare, submit and push your app through approval without the back-and-forth landing on your desk.
-
Security and privacy built in
Secure storage, proper authentication and privacy compliance designed in from the first sprint, not patched in before submission.
-
Since 2008, still hands-on
18+ years building for startups, SMEs and enterprises across the US, UK, Canada and India. Most support requests get answered inside your working day, not ours.
Questions, answered
Mobile app development FAQs
Should I build native or cross-platform?
Native development with Swift or Kotlin offers the best platform-specific performance and experience, making it ideal for graphics-heavy or deeply integrated apps. Cross-platform development with React Native or Flutter uses a shared codebase, making it faster and often more cost-effective to launch on both platforms. We recommend the approach that best fits your app's requirements.
How much does it cost to build a mobile app?
Mobile app development depends on the platform, features, design and backend requirements. A focused single-platform app is simpler, while multi-platform or enterprise apps with custom backends require more development. We scope each project individually and provide a clear, itemized quote before work begins.
How long does it take to build an app?
A focused single-platform app typically takes 10 to 16 weeks from first wireframe to store submission. Larger or enterprise apps run longer. You see designs early and a working build every week, so progress is never a mystery.
Do you build for both iOS and Android?
Yes. We build native for each platform separately, or cross-platform with React Native or Flutter to serve both from one codebase. We will tell you honestly which approach fits your goals and budget best.
Do you handle App Store and Play Store submission?
Yes. We prepare listings, assets and metadata, submit to both stores and manage the review process end to end, including resolving rejections, so the app actually goes live.
Do you design the app or just build it?
Both. We offer research-led UI/UX design from wireframes through to a polished, tested interface and a reusable design system, or we build cleanly from designs you already have. Design is not an afterthought here.
Can you build the backend too?
Yes. Most apps need APIs, a database, authentication and push notifications behind them. We build the backend alongside the app so the two fit properly, or integrate with systems you already run.
What happens after the app launches?
An app is a living product. iOS and Android push updates that can break things overnight, and users expect it to keep improving. Most clients move onto a maintenance plan covering monitoring, OS-update readiness, fixes and new features.
