Why Now

Nigeria has 220M people and 40M smartphone users. Most apps treat them as afterthoughts.

Global apps are built for 5G in London and San Francisco. They are heavy, slow and assume reliable internet — conditions that describe almost none of Nigeria. Nigerian users delete apps that stall on 3G. Apps that crash when network drops get one-star reviews and get uninstalled.

We build mobile applications with offline-first architecture as a default, not a feature. Data sync, local storage, background fetch and intelligent caching are baked in from day one. We design for the actual Nigerian user experience.

The result: apps that work, get kept, and drive the business outcomes our clients measure.

Our Process

How a Mobile Apps project gets built.

Every project follows a structured, phased delivery process. Each phase has a defined deliverable, a sign-off milestone and a go/no-go before the next phase begins. You see exactly where your project stands at all times.

Phase 1
Discovery & UX Research
User research with target Nigerian users, competitor analysis, information architecture and wireframe prototypes.
2 weeks
Phase 2
UI Design
High-fidelity Figma designs — all screens, states and micro-interactions. Dark and light themes. WCAG 2.1 accessibility compliance.
2–3 weeks
Phase 3
Development Sprints
Two-week sprints. Feature builds with daily TestFlight/Play Store internal builds. Weekly demos. Full Git history.
6–16 weeks
Phase 4
QA & Device Testing
Manual testing on 8 target Nigerian devices (Tecno, Infinix, Samsung mid-range). Network simulation: 2G, 3G, offline.
2 weeks
Phase 5
App Store Submission
Google Play and Apple App Store submission. Review management, metadata optimisation and screenshot production.
1–2 weeks
Phase 6
Post-launch Support
Crash monitoring via Sentry, analytics via Mixpanel, push notification campaigns and monthly app updates retainer.

FAQ

Common questions answered honestly.

Do you build for both iOS and Android?
Yes. We default to React Native or Flutter for new projects — one codebase, both platforms — which significantly reduces cost and time without sacrificing performance or native feel. For performance-critical applications (e.g. real-time video, heavy camera use), we build native Swift (iOS) and Kotlin (Android).
How do you handle Nigeria's network conditions?
Offline-first is our default architecture. We use SQLite or Realm for local data storage, implement background sync queues for operations taken offline, compress API payloads aggressively, and test every build on 2G and 3G network throttling. We also implement intelligent prefetching for predictable user flows.
Can you redesign or rebuild an existing app?
Yes. We do full redesigns, performance rewrites and platform migrations. We start with a technical audit of the existing codebase, identify the rebuild vs refactor boundary, and deliver a phased plan. We have rebuilt apps that were being deleted due to crashes and restored them to 4.5+ star ratings.
What is the App Store rejection rate for your submissions?
Our first-submission approval rate is over 90%. We know the common Apple and Google rejection reasons and address them proactively — privacy policy requirements, content guidelines, screenshot specifications and metadata rules. In the rare case of rejection, we resolve and resubmit within 3 business days.
