APP DEVELOPMENT
Turn your app idea into a product people can’t put down.
We design and develop native and cross-platform mobile apps that solve real problems, delight users, and drive business growth – from concept to App Store launch and beyond.
From idea to launch – and everything in between
Building a successful mobile app is more than writing code. It requires deep understanding of your users, sharp product thinking, bulletproof architecture, and pixel-perfect execution.
At Stragenix, we partner with startups, SMBs, and enterprises to turn app ideas into polished, market-ready products. Our team handles every phase – discovery, UI/UX design, development, testing, deployment, and post-launch support – so you get a single, accountable partner for your entire app journey.
We don’t just build apps. We build products that users love, investors notice, and businesses rely on.
iOS App Development
Native iOS apps built with Swift and SwiftUI, following Apple’s Human Interface Guidelines. Optimised for performance, App Store approval, and seamless user experience across iPhone and iPad.
Android App Development
Native Android apps built with Kotlin and Jetpack Compose. Designed for the full range of Android devices, following Material Design principles and Google Play requirements.
Cross-Platform Development
Reach both iOS and Android with a single codebase using React Native or Flutter. Faster time-to-market, lower development costs, and near-native performance and user experience.
Backend & API Development
Scalable backend systems, RESTful and GraphQL APIs, database architecture, authentication systems, and third-party integrations – the invisible engine that powers your app.
QA Testing & Quality Assurance
Comprehensive testing across devices, OS versions, and network conditions. Functional testing, performance testing, security testing, and user acceptance testing – before a single user touches your app.
Fintech & banking apps
Digital wallets, payment apps, investment platforms, and banking solutions – built with bank-grade security, encryption, and regulatory compliance.
Discovery & product strategy
We define your target users, core features, business model, and success metrics. Competitive analysis, user personas, and a product roadmap – before writing a single line of code.
UI/UX design & prototyping
Wireframes, interactive prototypes, and high-fidelity designs validated with real users. You see and test your app before development starts – reducing risk and rework.
Agile development
We build in 2-week sprints with regular demos and feedback loops. You see progress constantly, provide input early, and stay in control of scope and priorities.
Testing & QA
Rigorous testing on real devices across OS versions and conditions. We catch bugs before your users do – functional, performance, security, and usability testing.

Frequently asked questions
It depends on your requirements. Native apps offer the best performance and platform-specific features. Cross-platform (React Native/Flutter) saves time and budget when you need both iOS and Android. We’ll recommend the best approach after understanding your project.
A simple app starts from $15,000-$25,000. Medium-complexity apps range from $30,000-$80,000. Complex apps with advanced features can exceed $100,000. We provide detailed estimates after the discovery phase.
A simple app takes 2-3 months. Medium-complexity apps take 4-6 months. Complex applications may take 6-12 months. We provide realistic timelines during the discovery phase.
Yes. We offer ongoing maintenance, bug fixes, OS compatibility updates, performance monitoring, and feature development. Most clients stay with us on a monthly retainer after launch.
You do. 100%. All source code, designs, and assets are transferred to you upon project completion. You own everything we build for you.
Absolutely. We frequently augment existing teams – whether you need additional developers, a dedicated designer, or a technical lead to guide the project.
