Overview

One codebase. Two platforms. Native experience.

With over 80% mobile penetration across East Africa, your business needs a mobile presence that works flawlessly — regardless of whether users are on iOS or Android, on fast 4G or slow 2G, or offline in a remote area.

We build with React Native — Meta's battle-tested cross-platform framework used by apps serving billions of users (Facebook, Instagram, Shopify). It delivers true native performance while dramatically reducing development time and cost compared to building separate native apps.

Every app we build is engineered for the African market: offline-first data architecture, M-Pesa and mobile money integrations, optimized for low-end Android devices, and built for the specific workflows of your industry.

Core Capabilities

Everything you need, nothing you don't

Every capability is purpose-built to deliver measurable results for your business.

Cross-Platform Development

One React Native codebase deploys to both iOS and Android. Share 95%+ of code while delivering platform-specific UI conventions users expect.

Offline-First Architecture

Apps that work seamlessly without internet. Local storage syncs automatically when connectivity returns — critical for field workers and rural areas.

Mobile Money Integration

Native M-Pesa (Vodacom), Airtel Money, Tigo Pesa, Halopesa, and international card payment integrations. C2B, B2C, and STK push flows.

Push Notifications

Targeted push notifications via Firebase Cloud Messaging and APNs. In-app notifications, deep links, and notification scheduling.

Location & Maps

Real-time GPS tracking, geofencing, route planning, and map visualization using Google Maps SDK and Mapbox for delivery, field, and logistics apps.

Device Hardware Integration

Camera (photo/video/QR/barcode scanning), biometric auth, NFC, Bluetooth, accelerometer, and file system access — full native device capability.

In-App Analytics

Embedded usage analytics, crash reporting (Sentry), custom event tracking, and A/B testing to understand how users interact with your app.

Security & Authentication

JWT authentication, biometric login, encrypted local storage, certificate pinning, and anti-reverse-engineering measures for sensitive apps.

OTA Updates

Over-the-air updates via Expo EAS. Push JavaScript updates to users instantly without requiring App Store review — faster iteration cycles.

What you receive at delivery

Everything documented, packaged, and handed over — no ambiguity.

iOS + Android Apps

Production-ready APK and IPA builds submitted to both app stores.

Full Source Code

Complete React Native source code on GitHub with CI/CD pipeline.

Backend API

Django REST API serving the mobile app with full documentation.

Admin Dashboard

Web-based admin panel to manage users, content, and app data.

Test Suite

Unit and integration tests with minimum 80% code coverage.

App Store Listing

App icon, screenshots, descriptions, and keyword optimization for both stores.
