Website & Web App Development
Marketing websites and logged-in web apps built in Next.js, from a five-page brochure site to a full customer portal.
An app that works on slow connections too
We build for iOS and Android from one codebase, test on real devices and handle submission to both app stores.
Oneshot Digital Hub is a global technology services company that builds cross-platform apps in React Native or Flutter for iOS and Android, moving to native code only when a project genuinely needs it, for founders and businesses in Nigeria, the UK, the US and Europe. You receive a tested app, app-store submission, offline-first handling for low-bandwidth conditions, and post-launch monitoring.

What does Mobile Apps include?
A mobile app puts your service on a customer's phone rather than behind a browser tab, with push notifications, offline access and a faster experience than a mobile website can match. For businesses in Nigeria and similar markets, that also means designing for patchy connectivity and lower-cost devices from the outset, not as an afterthought once the first version is slow.
We build in React Native or Flutter so the same codebase serves iOS and Android, which keeps cost and maintenance down for most business apps; we move to native Swift or Kotlin only when a feature genuinely needs it, such as heavy camera or hardware use. Every build is designed offline-first, caching data so the app remains usable when a connection drops.
We start with a written scope covering every screen and permission the app requests, then build in short cycles with a working build on your phone each week. Before submission we test on real low- and high-end devices, submit to the Apple App Store and Google Play on your developer accounts, and monitor crash reports after launch.
App architecture and data model
A documented plan for screens, data storage and offline behaviour before development starts.
React Native or Flutter build
A single codebase running natively on both iOS and Android devices.
Offline-first data handling
Local caching so core features keep working when the connection drops or is slow.
Push notification setup
Configured alerts for orders, reminders or updates delivered directly to the customer device.
App store submission
Listings prepared and submitted to the Apple App Store and Google Play under your accounts.
Device and network testing
Testing across device sizes and connection speeds, including low-bandwidth conditions common in Nigeria.
Source code and documentation
The full codebase and a written handover guide, held in a repository you own.
Post-launch monitoring setup
Crash and performance monitoring configured so issues are visible after go-live.
Who is Mobile Apps for?
Delivery app for a Lagos firm
A logistics company in Lagos needs riders and customers tracking orders on patchy mobile data.
Booking app for a UK clinic
A UK-based clinic wants patients booking and managing appointments from a branded app instead of phone calls.
Loyalty app for a retail chain
A retailer with several branches wants one app for offers, points and store locations.
Field app for remote teams
Field staff need an offline-capable app for logging visits or readings where signal is unreliable.
Companion app for an existing platform
A business with a web app wants a mobile companion covering the features customers use most.
- One codebase covering both iOS and Android users
- An app that stays usable on slow connections
- Clear ownership of source code and app store listings
- A tested, submitted app ready for real customers
How does the work run?
01
Discovery and alignment
We learn what you want to change, who it affects, and confirm the goal and scope in writing.
02
Strategy and architecture
We plan the solution, stack and security model, then send a proposal with fixed scope, timeline and price.
03
Design and prototyping
You review wireframes or a clickable prototype and approve the direction before production code is written.
04
Engineering and development
We build in short, reviewed increments and show you working software in a weekly demo.
05
Security, testing and launch
Every release passes a security review, automated tests and a launch checklist before it goes live.
06
Continuous optimisation
After launch we monitor, measure and improve the system against the goal agreed at the start.
What does it cost?
From $5,000. Typical timeline: 8–16 weeks.
Prices depend on scope; every engagement gets a written fixed-price proposal after a discovery call. Mobile app projects typically start from $5,000, and Nigerian clients can pay in naira by bank transfer.

FAQ
Questions about Mobile Apps
How long does a mobile app take to build?
Most mobile apps take 8–16 weeks from discovery to app-store submission, depending on features and integrations. Your written proposal states the exact range for your project.
What does a mobile app project cost?
Prices depend on scope; every engagement gets a written fixed-price proposal after a discovery call. Mobile app projects typically start from $5,000, and Nigerian clients can pay in naira by bank transfer.
Do you build native apps or React Native and Flutter?
We build in React Native or Flutter by default, since one codebase covers iOS and Android at lower cost. We move to native Swift or Kotlin only when a feature genuinely requires it.
Can the app work without an internet connection?
Yes; we design core features to work offline and sync automatically once a connection returns, which matters for users on patchy or expensive mobile data.
Who submits the app to the App Store and Google Play?
We prepare the listing and submit under your own developer accounts, so you keep ownership and control of the published app.
