Revolutionizing Networking at Exhibitions with Mobile Technology

Helpie Logo



Helpie is a cutting-edge mobile application that aims to transform the way users interact and network at exhibitions and events. By leveraging card scan and QR code scan technology, the app provides a seamless and efficient solution for users to capture and store important details from business cards and set reminders for follow-ups.

This case study delves into the development and implementation of Helpie, highlighting its features, scope, and the technology stack powering its functionalities.


Problem Statement

Traditional networking at exhibitions involves the manual exchange of business cards and the challenge of remembering key interactions amidst a sea of new contacts.

The lack of an organized system to manage and follow up with these contacts often results in missed opportunities and lost connections. Helpie recognized this problem and sought to develop an innovative mobile application that simplifies networking and optimizes post-event follow-ups.

User Support & Help Center

A dedicated support team and help center were established to address user inquiries and provide prompt assistance.


UI Design

After finalizing the IA through several iterations, we proceeded with the wireframes. The high-fidelity wireframes created were then advanced to the visual design stage. Our primary focus was to address the pain points and opportunities of each person while designing. To achieve this, we ensured a smooth and straightforward onboarding process, followed by a visually-rich, dynamic, and intuitive homepage.

The core concept was to enable users to complete an activity with minimum effort, using just a few taps, and with minimal cognitive load. By keeping the design simple and straightforward, we aimed to enhance the user experience and ensure that the app was easy to use.
