Overview & Use Cases

We build custom Android and iOS applications and cross-platform solutions (Flutter / React Native) that focus on security, offline capability, and seamless integration with back-end systems like ERPNext and Frappe CRM. Typical use-cases include field data collection, beneficiary registration, staff coordination, monitoring & evaluation, and mobile commerce.

  • Offline-first field data collection apps (images, GPS, forms)
  • Mobile dashboards for managers and donors
  • Secure API integrations with ERP/CRM systems
  • Multilingual apps (Arabic, English, Swahili)
  • Low-bandwidth optimizations and progressive sync

Core Features

Offline Sync & Reliability

Collect data offline and automatically sync when the device regains connectivity.

Secure Data Storage

Encrypted local storage + secure transport to the central database (HTTPS, TLS).

Real-time Reporting

Live dashboards and alerts for program managers and donors.

ERP & CRM Integration

Seamless API-based sync with ERPNext, Frappe CRM, or custom backends.

Low-end Device Optimization

Performance tuned for older Android devices common in East Africa.

User Access Control

Role-based access, audit logs, and secure authentication (Firebase/Auth providers).

Technology & Integrations

We build using modern frameworks and tools focused on speed and reliability.

  • Flutter / React Native / Native Android
  • Firebase / Firestore for realtime sync

Case Study: CSLO Mobile Field App

We built a lightweight mobile app for CSLO that allowed field officers to capture beneficiary surveys, GPS coordinates, and incident reports offline — then sync to a secure ERPNext backend when online. The solution improved reporting accuracy and, as part of the wider ERPNext platform, helped cut manual data entry time by 70%.

Problem

Field teams could not reliably send reports due to poor connectivity.

Solution

Offline-first Android app with secure sync and minimal bandwidth usage.

Impact

Data accuracy improved; as part of the wider ERPNext platform, manual data entry time cut by 70% and donor reporting 50% faster.

Frequently Asked Questions

Common questions about our services, pricing, and processes

We develop for both iOS and Android using React Native, which produces a single codebase that runs natively on both platforms. For projects where native device APIs or performance requirements demand it, we can build platform-specific versions. We advise on the right approach during scoping based on your user base and budget.
A focused app with a defined feature set — field data collection, beneficiary registration, staff scheduling — typically takes eight to fourteen weeks from requirements to app store submission. More complex apps with real-time sync, offline-first architecture, or third-party integrations run fourteen to twenty-four weeks. We provide a firm estimate after the requirements phase.
Offline-first capability is a design requirement we treat as standard for apps deployed in East Africa and humanitarian contexts, not an optional add-on. Data is stored locally on the device and syncs to the server automatically when a connection is available. Field teams in low-connectivity zones in Sudan, Uganda, and rural Rwanda rely on this behaviour in apps we have built.
We build the app's API layer to exchange data directly with ERPNext or any back-end system with an accessible API. Field submissions — beneficiary records, incident reports, distribution data — flow into the ERP in real time once synced. This eliminates manual re-entry and gives program managers live visibility into field operations.
Yes. We prepare all required assets — screenshots, app descriptions, privacy policy, and review responses — and manage the submission process for both the Apple App Store and Google Play Store. Approval timelines are set by the stores, but we handle everything on your behalf.
For apps handling beneficiary data, health records, or confidential field information, we implement encrypted local storage, secure token-based authentication, certificate pinning to prevent API interception, and role-based data access so users only see records relevant to their assignment. We align these controls with our broader cybersecurity service standards.
