Illustration: the same app listing, Amaka Foods, published either under an individual account (seller Amaka Obi, verified with a government ID) or an organisation account (seller Amaka Foods Ltd, verified with a D-U-N-S number), moving from a Flutter build to published on Google Play and ready for sale on the App Store.

Why a mobile app
Closer to your customers than their closest friends.
The smartphone is the one thing people keep within arm’s reach all day. A website can only visit it. An app lives on it, and, with the user’s permission, can use the phone’s own features to serve them better.
That makes a mobile app the most direct line to your audience.

Why Flutter
One team. One language. Every platform.
Your customers use different phones, and each runs a different operating system: Android on a Samsung, iOS on an iPhone. Building a native app for each one usually means hiring a separate developer for each. Flutter is our official tech stack because it removes that duplication.
The traditional way
A different hire for every platform
- Product engineerUser flows & diagrams
- Product designerUI/UX
- iOS / macOS developerSwift or Objective-C
- Android developerKotlin or Java
- Windows developerC# / .NET
- Higher cost
- Longer timeline
- Harder to manage

Building a startup?
Start with an MVP. Grow on proof.
A minimum viable product is the smallest version of your app that real users can download and pay for. It’s the fastest way to test your idea and the strongest thing to show investors.
- PHASE 1 · MVP
Your core feature
The one job your app must do well, live on the store and in real hands. Often in about 4 weeks.
- PHASE 2 · GROW
What users ask for
Add the next feature with real usage data behind the decision.
- PHASE 3 · SCALE
New markets
More cities, more users, deeper integrations and a stronger backend.
Investors fund focus. Prove demand in one market, then expand with numbers to back it. We can also design your brand and investor pitch deck.
Before you publish
What you need to publish a mobile app
Every app on Google Play and the App Store is published from a developer account. The type of account decides whose name appears as the publisher: yours or your company's.
Individual account
The app is published in your personal name. You verify your identity with a government-issued ID. In most cases an International Passport will do.
Organisation account
The app is published in your company's name. You verify yourself and your company, using a D-U-N-S number: a global business ID from Dun & Bradstreet.
Getting a D-U-N-S number
- Company registered in the USA, UK or Europe
- Free, fast
- Company registered in Nigeria (CAC)
- 7–30+ days
Nigerian companies submit their CAC documents and wait for approval. We prepare the application and can fast-track it.
Developer account fees
- Apple Developer
- $99per year
- Google Play
- $25once, for life
Once your account is set up, you can publish as many apps as you like on it.
Costs, explained
