Phone Tracker App

πŸ’‘ Project Idea

The concept was to build a real-time phone tracker and location-sharing app that also integrates safety features like a Speed Meter. The app is ideal for people who want to stay connected, monitor movement, and promote responsible driving.


🧾 Client Requirements

  • Platform: Android (initial phase)
  • Requested Features:
    • Live mobile number tracking
    • Live location updates
    • Speed meter to monitor driving
    • Call-related geolocation UI
  • Delivery Deadline: 10–12 weeks
  • Target Audience: General users for personal tracking, parental safety, and navigation support

πŸ“„ Documents & Technical Plan

  • Functional Modules Documented:
    • Real-time GPS location module
    • Speed tracking and location history
    • Permission management for location services
    • UI/UX flow for seamless access to location tools
  • Languages & Stack:
    • Language: Dart (Flutter) for fast, cross-platform development
    • Native integrations for GPS and telephony state (on Android)

🎨 Design / Prototype

  • Created using Figma
  • Design Focused On:
    • Clear, card-based layout for tracking and live maps
    • Speed meter visual with analog and digital display
    • Easy toggle controls for sharing location
    • Clean typography for readability

βš™οΈ Development

Framework & Tools:

  • Flutter (Dart) – for frontend & UI
  • Google Maps SDK – for map and location tracking
  • geolocator, location, permission_handler – for real-time GPS handling
  • speedometer_flutter, flutter_compass – for speed tracking and orientation
  • Shared Preferences – for storing user data and logs
  • Firebase Crashlytics – for bug reporting and crash tracking

Key Features:

  • Number Tracker: Locates devices associated with specific numbers
  • Live Location: Real-time GPS sharing
  • Speed Meter: Measures movement speed in km/h or mph
  • Map Integration: View current and past locations visually
  • Low Battery Optimized Tracking: Efficient background usage

πŸ§ͺ Quality Assurance

  • Manual testing for permissions, speed accuracy, and device compatibility
  • Verified battery efficiency and GPS responsiveness
  • Fixed bugs related to:
    • GPS freeze on certain devices
    • Speed meter inaccuracies at low speeds
    • Inconsistent background tracking on Android 10+
  • Fully tested on real devices and emulators

πŸ“² Publish Platforms

  • βœ… Android (Google Play Store)
  • πŸ• iOS version planned (subject to permissions and GPS limitations)
  • 🌐 Web dashboard not required for this version

⚠️ Challenges Faced

  • Real-time tracking without draining the battery
  • Maintaining high GPS accuracy across all devices
  • Location permissions handling for Android 10, 11, and newer
  • Adhering to Google Play policies for sensitive permissions (location, call state)
  • UI optimization for low-end devices

⏳ Estimated Development Time

Total Duration: 10–12 Weeks

  • Week 1–2: UI/UX design and GPS integration setup
  • Week 3–5: Number tracker and live location module
  • Week 6–7: Speed meter implementation and optimization
  • Week 8: Full testing and bug fixing
  • Week 9–10: Play Store review and app publishing

πŸ’° Estimated Cost

  • Backend Server: Not required (Local device-based tracking)
  • Cost-effective cloud use avoided to maintain privacy
  • Estimated Budget: $600 – $800
  • Cost optimized via Flutter’s cross-platform nature and open-source libraries
  • Firebase used only for analytics and crash tracking
