iOS & Android App Development Built for Real-World Performance
StrattonX Technologies builds cross-platform and native mobile apps that users love and keep using. From MVP to production: clean UX, fast performance, offline support, payments, and everything your business needs to win on mobile, shipped by one accountable team.
Our Mobile Apps Services
The mobile app development services at StrattonX Technologies cover iOS and Android from initial concept through App Store launch and beyond. We build cross-platform apps in React Native and Flutter, and native apps in Swift or Kotlin when performance demands it, always recommending the architecture that serves your users and your budget, not the one that pads our invoice.
Successful mobile app development is as much about product design as engineering. The apps that win in competitive app stores are the ones users find intuitive, fast, and genuinely useful. That is why our process begins with UX research and an interactive prototype, validating the experience with real users before production code is written, so we build the right product the first time.
From consumer apps chasing growth to enterprise tools deployed across field teams, StrattonX Technologies handles the entire journey: product definition, UI and UX design, cross-platform or native development, QA, App Store and Google Play submission, and post-launch App Store Optimization. One team, a fixed scope you approve up front, and code you fully own.

Our Mobile Apps services have helped businesses across 5 countries achieve breakthrough results. From startups to established enterprises, we deliver for clients across the USA, UK, Australia, New Zealand, and Germany.

What our clients say about
Mobile Apps
“The UX process made the difference. They prototyped and tested with real users before building, and it shows in how naturally people take to the app.”
“A complex delivery app with real-time tracking, multiple user roles, and payments, delivered on schedule with builds we could test every two weeks. Excellent engineering discipline.”
“They built exactly what we envisioned: gamification, offline mode, audio lessons, all of it. Communication was clear from kickoff to launch.”
Frequently Asked Questions
How much does it cost to build a mobile app?
A focused MVP app for one platform with core features typically ranges from $25,000 to $55,000. A cross-platform app development project covering iOS and Android with backend integration, real-time features, and in-app payments more typically runs $60,000 to $150,000. StrattonX Technologies provides a fixed-price quote after a free product discovery session, so you know the full cost before committing.
Should I build a native app or a cross-platform app?
For most businesses, cross-platform app development with React Native or Flutter delivers an excellent user experience at 30 to 40 percent lower cost than building two separate native apps. We recommend native Swift or Kotlin development only when you need maximum performance, such as AR, complex graphics, or heavy camera processing.
How long does mobile app development take?
A focused MVP typically takes 8 to 12 weeks from design to App Store submission. More complex apps with real-time features, custom backends, or heavy integrations take 12 to 20 weeks. You receive working builds on TestFlight and Google Play Beta every two weeks throughout development.
Can we hire React Native developers from StrattonX Technologies for our existing team?
Yes. Alongside full project delivery, you can hire React Native developers from StrattonX Technologies to extend your in-house team, with flexible engagement lengths and time zone overlap for US, UK, and Australian working hours. You interview the developers before they join your team.
Do you help with App Store Optimization after launch?
Yes. App Store Optimization is included in our launch service: keyword research for your app title and subtitle, high-converting descriptions, compelling screenshots and preview videos, and early review generation, so your listing converts browsers into downloads from day one.
Can you maintain and update the app after launch?
Yes. StrattonX Technologies offers post-launch maintenance retainers covering OS update compatibility, bug fixes, performance monitoring, and ongoing feature sprints. Apps that go unmaintained fall in store rankings and accumulate technical debt, so we keep yours current as iOS and Android evolve.
