Multiple Utility Functions
Different everyday tools needed to work together within one mobile application.
Dual Space: Multi Accounts
Centangle worked on Dual Space as a consumer mobile application focused on bringing several everyday digital utilities into one convenient experience. The product combines QR code tools, contact management, digital notes, social network access, and multi-account functionality within one mobile application.

Project Overview
Dual Space was developed as a multi-purpose mobile utility that combines QR tools, contact organisation, digital notes, and social account access within one application, helping users manage different everyday digital tasks from one place.

The Mandate
The project focused on bringing commonly used mobile functions into one product while keeping each utility easy to access, understand, and use without making the overall experience feel crowded or complicated.
The Environment
Users often rely on separate applications for QR scanning, QR generation, contacts, notes, and social account access, creating fragmented digital journeys for tasks that are frequently completed throughout the day.
Our Role
Centangle worked on the Dual Space mobile experience by bringing its different utility functions into one structured application designed around simple navigation, quick feature access, and everyday mobile use.
The Challenge
Combining several unrelated utilities within one application can quickly make the product difficult to navigate. Users may enter Dual Space to scan a QR code, manage contacts, access notes, or use a social account, meaning each function needed to remain easy to find and understand.
The challenge was to bring these different workflows together while maintaining a clear and consistent mobile experience.

Different everyday tools needed to work together within one mobile application.
Users needed to reach the function they required without unnecessary navigation.
Users managing multiple social accounts needed a simpler way to access different account contexts.
Different utilities needed to feel like parts of one connected product rather than separate tools.
The Solution
Centangle developed Dual Space as a multi-purpose mobile experience that brought QR code tools, contacts, digital notes, and social account functionality together within one organised application. The product gave users a central place to access commonly used utilities while keeping individual workflows simple and focused.
