Project Overview

A Mobile-First Maintenance Tracker Built with Flutter — From Concept to Google Play

Vehicle owners face a common problem — keeping track of maintenance schedules across multiple cars is tedious, and most people rely on paper logs, generic calendar reminders, or simply forget. CarCare was designed to solve this with a dedicated, intuitive mobile-first experience that makes vehicle maintenance tracking effortless. The client, MobiGames, needed a polished consumer app ready for the App Store and Google Play within a 10-week timeline — built in Flutter for a single codebase across both platforms.

We built the entire app in Flutter using the BLoC pattern for state management — giving us a clean separation between business logic and UI that made the app easy to test and extend. The backend runs on Firebase Firestore for real-time data sync across devices, Firebase Authentication for secure sign-in, and Firebase Cloud Messaging for push notification reminders. The app was tested across 20+ physical devices before submission and passed the Google Play review on the first attempt. It launched with a 4.6/5 rating and 1,000+ downloads in the first month.

The Challenge

Building a polished, production-ready consumer mobile app in Flutter — with reliable push notifications, offline-capable data, and an onboarding flow simple enough for non-technical users — within a fixed 10-week timeline and across a wide range of Android device configurations.

Our Solution

We chose Flutter with BLoC architecture for its performance and testability. Firebase Firestore provides real-time data sync with offline caching so the app works without connectivity. Firebase Cloud Messaging handles push reminders reliably across both platforms. We designed a 3-step onboarding flow validated through internal UX testing, and ran the app on 20+ physical devices — covering low-end Android hardware — before submission to ensure consistent performance everywhere.

The Result

CarCare launched on Google Play with a 4.6/5 user rating and reached 1,000+ downloads in its first month — with zero critical bugs reported post-launch. The onboarding completion rate reached 91%, validating the UX design decisions. The app passed Google Play review on the first submission with no policy violations or technical rejections.
