Private VPN App

🔍 About the Project

Smart VPN was created to provide fast, secure, and hassle-free internet access for everyone. Whether you're traveling, shopping online, or just scrolling social media, Smart VPN gives you one-tap privacy with global servers and military-grade encryption — all in one lightweight app.

🧩 What the Client Needed

The client approached us with a clear goal:

• Create a powerful yet lightweight VPN app
• No login or sign-up required
• Include speed test, auto server selection, and premium access
• Publish the app on Android, iOS, and their official website
• Deliver within 10 weeks

We accepted the challenge and delivered a robust cross-platform VPN solution.

📄 Planning & Technical Blueprint

Before development, we finalized a detailed tech roadmap and user experience flow.

Key decisions included:

• UI/UX Design: Clean, minimal, accessible to all age groups
• Languages: Flutter (Dart)
• VPN Protocols: OpenVPN & WireGuard
• Cloud Infrastructure: Firebase + VPS-based VPN hosting
• Tools Used: Figma (Design), Postman (API Testing), Git (Version Control)

🎨 Designed to Be Simple & Smart

Our design team used Figma to build a fast, intuitive UI:

• One-tap connect
• Dark/light mode
• Instant speed test feature
• Language localization options
  The design prototype was shared early for user testing and client feedback.

🛠️ Built with Flutter — Fast, Flexible, Future-Proof

Using Flutter allowed us to build once and deploy everywhere.

What we used:

• Flutter (Cross-platform UI)
• Dart (Programming language)
• flutter_secure_storage for local data security
• Speed test API for accurate connection testing
• Custom VPN wrapper logic for OpenVPN control
• intl for multilingual support

✅ Quality You Can Trust

We tested the app across:

• Android (API 21 to latest)
• iOS (iPhone 8 to iPhone 15)
• Network types (3G/4G/5G/Wi-Fi)
  Testing Goals:
• No drops in VPN connection
• Fast server switching
• Zero UI glitches
  Result: A smooth, stable experience, even on low-end devices.

📲 Published Where Your Users Are

Smart VPN is now available on:

⚠️ Challenges We Overcame

• Integrating OpenVPN with Flutter was complex due to native dependencies
• Apple’s strict VPN policy required several compliance iterations
• Auto server ping testing under poor network conditions
• Keeping the app under 20MB while supporting multiple languages

📆 Project Timeline

Our team delivered Smart VPN in just under 12 weeks:

• Week 1–2: Design & User Flow Finalization
• Week 3–6: Flutter Frontend + Backend Integration
• Week 7–9: VPN Protocol Implementation
• Week 10–11: QA Testing & Bug Fixing
• Week 12: App Store Deployment

💰 Cost & Server Setup

Server Locations: 6 VPS (US, Canada, India, UAE, Germany, UK)

Cloud Tools: Firebase, GitHub, Postman

Estimated Project Cost: $1000–$1200

We used VPS-based server hosting to maintain performance while optimizing cost — a perfect balance of value and performance.
