Single Unified System vs. Separate App Teams
How a single codebase delivers complete phone and web coverage without bloated costs:
| Feature | Separate App Development | Patnai Unified System |
|---|---|---|
| Development Approach | Requires building 3 separate apps for Android, iPhone, and Web | Single unified system that runs on Web and installs on Mobile |
| Delivery Timeline | 3 to 6 Months with high coordination overhead | 14 to 21 Days focused production sprint |
| User Installation | Customer must search App Store and download 100MB+ file | 1-Tap install icon added directly to customer's home screen |
| Storage on Customer Phone | Takes 50MB – 150MB space (Users delete when memory is low) | Takes under 2MB (Loads instantly, users keep it installed) |
| Offline / Low Signal Loading | Works offline | Works smoothly even in low network or offline mode |
| Customer Push Notifications | Supported | Supported — send direct updates & offers to customer screens |
