Capabilities

Mobile App Development Services in Lagos

Our application developer teams build modular, secure apps for iOS and Android, designed for how people in Nigeria actually use their phones: mobile payments with Paystack and Flutterwave, and offline-friendly experiences for patchy connectivity.

Flutter Development & Cross-Platform Apps

Our Flutter development team builds iOS and Android apps from a single codebase, with smooth native-quality performance. It is usually the fastest, most cost-effective route to launch an MVP on both platforms.

Got Questions?

Mobile App Development: Frequently Asked Questions

Answers about hiring app developers, choosing Flutter or native, timelines, and store approval.

How do I choose the best mobile app developers for my business?

Look at the developers' shipped apps and client references, ask who will actually build your product, and confirm what is included: design, development, testing, store submission and support. Get scope, timeline and price in writing.

Why choose Flutter development over native iOS and Android development?

Flutter lets one codebase serve both iOS and Android, which usually lowers cost and speeds up launch. If your app needs deep OS-level features, we can build natively with Swift and Kotlin instead.

How much does mobile app development cost and how long does it take?

Cost and timeline depend on features, platforms, integrations and design. A focused MVP is the fastest and most affordable way to launch. We review your idea and send a written estimate with scope and timeline.

Will you handle Google Play Store and Apple App Store submission?

Yes. We handle store listings, privacy and data-safety declarations, screenshots and the submission process, and help resolve review feedback from Apple or Google.

Do I own the app's source code and intellectual property?

Yes. You own the source code, design files and project assets, and we hand over documented repositories and deployment details.

Are you mobile app developers based in Lagos?

Yes. Data Megathos is based in Lagos, Nigeria, and builds apps for startups and businesses across Nigeria and beyond, working with clients remotely.
