WiFi Analyzer – Speed Test App

💡 Project Idea

The goal was to create an intuitive app that allows users to analyze WiFi signals, run speed tests, detect intruders, and optimize router settings — all from a single interface. The app also includes a QR Scanner and Password Generator to enhance usability and security.

🧾 Client Requirements

• Platform: Android only (initial release)
• Key features requested:
  • WiFi Signal Analyzer
  • Internet Speed Test (Upload/Download)
  • Device Scanner for network security
  • QR Code Scanner & Password Generator
  • User-friendly dashboards and graphs
• Completion deadline: within 10 weeks

📄 Documents & Technical Planning

• Functional flow diagrams and feature architecture
• API integration plan for speed test servers
• Permissions handling for location, network state, and camera
• Language: Dart (Flutter) for cross-platform readiness
• Dependencies: WiFi info, QR scan, speed test, and chart rendering plugins

🎨 Design / Prototype

Figma was used to design the app's layout and navigation:

• Clean, minimalist interface
• Dashboard-style home screen with signal strength indicators
• Graphs for signal fluctuation & speed test results
• Tabs for QR scan, network devices, and password tools

⚙️ Development

Tech Stack:

• Flutter (Dart) – Cross-platform app development
• Libraries Used:
  • wifi_info_flutter for signal strength and channel info
  • speed_test_dart for running speed tests
  • flutter_barcode_scanner for QR code scanning
  • flutter_local_notifications for alerting users
  • network_info_plus and ping_discover_network for scanning connected devices
  • fl_chart for real-time signal graphs

Core Modules:

• WiFi Signal Analyzer (strength, channels, quality)
• Speed Test Tool (ping, download, upload)
• QR Scanner for networks
• Device discovery for intrusion detection
• Secure password generator for WiFi/router use

🧪 Quality Assurance

• Manual and automated testing across Android devices
• Bug fixes for inconsistent signal readings and device discovery errors
• Optimized speed test functionality for low-speed networks
• Checked compatibility with both 2.4GHz and 5GHz bands
  Performance Checks:
• App load time < 3 sec
• Accurate signal fluctuation graphs
• Real-time updates and alerts for intruder detection

📲 Publish Platforms

• ✅ Android (Google Play Store)
• 🕐 iOS version planned for future update
• 🌐 Web dashboard support in roadmap

⚠️ Challenges Faced

• Handling real-time WiFi data refresh without battery drain
• Accurate speed test results from varying ISPs
• Permissions and OS-level restrictions on WiFi scanning in Android 10+
• UI optimization for devices with different screen sizes
• Securing sensitive user data during device scans

⏳ Development Timeline

Total Duration: ~10 Weeks

• Week 1–2: UI/UX design and technical setup
• Week 3–6: Core module development (WiFi, speed, scanner)
• Week 7: Advanced features (QR, password, device discovery)
• Week 8–9: Testing, bug fixes, performance enhancements
• Week 10: Play Store optimization, publishing, and analytics setup

💰 Estimated Cost & Server Requirements

• No external server required – all processes handled locally on device
• Cloud-Free to ensure privacy and reduce cost
• Estimated budget: $500 – $700
• Cost savings through Flutter reusability and minimal backend use
