Case Studies

Real work. Real outcomes.

Flutter apps built for businesses with real operational problems — not portfolio pieces.

Case studies

Distribution & Logistics

DistroBook — FMCG Distribution Management

The challenge

A South India FMCG distributor ran 6 delivery routes entirely on WhatsApp messages and paper forms. Orders had no audit trail, credit limits were tracked in notebooks, and the owner had zero real-time visibility into daily operations.

What we built

A Flutter mobile app for delivery agents covering route management, digital order capture, delivery confirmation with signature, and a running credit ledger per retailer. A Flutter Web admin dashboard gave the owner a live view of all routes, pending orders, and receivables — accessible from any browser.

100% of orders now captured digitally. Real-time owner visibility across all routes. WhatsApp order chaos eliminated.

Government & Public Sector

Fleet Operations — State Transport Authority

The challenge

A state transport organisation needed field-ready mobile tooling for drivers and conductors — trip log creation, passenger count entry, incident reporting, and daily handover — without relying on always-on internet connectivity across all routes.

What we built

An offline-first Flutter app using local SQLite storage with Firebase sync on reconnect. Drivers could complete their full shift workflow without a connection. A web supervisor dashboard showed real-time trip status where connectivity allowed, with batched sync from offline devices. Deployed across hundreds of devices.

Flutter SQLite Firebase Offline-first REST API

Deployed at scale across the operational fleet. Paper-based trip logging fully replaced. Zero data loss with offline sync architecture.

Public Safety

Field Operations App — Law Enforcement Unit

The challenge

A law enforcement unit needed a secure, reliable mobile app for field officers to submit structured reports, access reference data, and receive assignment updates — with strict data security requirements and no room for unreliable third-party tools.

What we built

A Flutter Android app with role-based access control, encrypted local storage, structured form submission, push notification for assignment dispatch, and an admin module for supervisors. All data handled through a secured backend API. Built to pass internal security review.

Flutter Android Encrypted storage RBAC REST API

Passed internal security audit. Replaced manual paper reporting for field officers. Deployed and in active use.

Agency White-label

App Rescue — Inherited Flutter Codebase

The challenge

A software agency inherited a Flutter project from a previous vendor — no documentation, outdated packages, build failures on Android 13+, and multiple crashes in production. Their client was losing patience.

What we built

We ran a structured 2-week audit: dependency map, architecture review, crash log analysis, and a prioritised fix list. Then stabilised the build environment, resolved Android and iOS compatibility issues, fixed the top 7 crash categories, and handed back a clean codebase with documentation — under AppTeky's name kept out of the client-facing project.

Flutter App Rescue Android 13+ White-label

Build restored and crashes reduced by 90% within 3 weeks. Agency retained their client. Now on ongoing maintenance retainer.
