Sign Partner Pro (SPP) and its companion app, SPP Lite, are revolutionary applications designed to transform the sign industry. Developed through a three-year collaboration with a freelancing client, these applications address the unique challenges faced by sign companies and end-users. By leveraging advanced technologies like Augmented Reality (AR) and streamlined project management tools, SPP simplifies the sign selling process and enhances customer experiences.

One of the standout features of SPP Lite is its AR functionality. Traditionally, sign salesmen relied on Photoshop to demonstrate how signs would look to potential customers, which was a time-consuming process. SPP Lite solves this problem by allowing users to select from a catalog of signs and view true-to-size representations of the signs on their property using AR. This immersive experience enables potential buyers to make informed decisions and visualize how the signs would look in real-world contexts.

SPP offers a suite of powerful project management tools tailored specifically for sign companies. With SPP, sign companies can create and manage projects, view all their projects on a map, manage events within a project, and access a "company calendar" view to easily track all events across multiple projects. The app also allows users to capture photos and videos of the site and store them directly in the project for future reference, streamlining the project management process.

SPP Lite introduces a game-changing feature that allows sign salesmen to upload generic or custom videos and use them as demonstrations for potential clients. Through the app, users can see their business showcased on an LED sign, enhancing the conversion rates and providing a more engaging sales experience. Technically, this is achieved by using a video picker for video uploads, which sends a reference of the file to Unity. Unity then renders the video on a sign using a custom LED matrix shader, creating a realistic and impressive visualization.

Sign Partner Pro is built using a combination of cutting-edge technologies, including Flutter for cross-platform mobile app development, Firebase for backend services and data storage, and Unity for AR functionality. One of the significant technical challenges faced during development was implementing offline support. SPP addresses this by storing all data and assets locally and synchronizing the data with the cloud whenever the device has internet access. When the app is launched, it attempts to download any new data since its last launch, ensuring a seamless user experience even in low-connectivity environments.

Data security and privacy are paramount in Sign Partner Pro. The app utilizes Firebase and Firestore security rules to ensure that only authorized users can access sensitive data. These measures safeguard project information and customer details, providing peace of mind to sign companies and their clients.

Sign Partner Pro has garnered significant attention and praise within the sign industry. It was showcased at ISA, a national sign trade show, where numerous sign companies expressed interest and became paying customers. This recognition highlights the app's effectiveness in addressing real-world challenges and its potential to revolutionize the sign industry.

Sign Partner Pro and SPP Lite represent a significant leap forward in sign sales and management. By harnessing the power of AR, streamlining project management, and offering innovative features like custom video uploads, these applications are transforming the way sign companies operate and interact with their customers. With its robust technology stack, offline support, and strong focus on data security, Sign Partner Pro is poised to become an indispensable tool in the sign industry.
