Robbox is a Canadian technology company developing smart digital power tools to bring construction into the connected world. I collaborated closely with their team to design the companion app for the Sennses Pro Digital Measuring Device while also refining the device’s UI/UX through iterative improvements.

When I began working with Robbox, the Sennses Pro was already an impressive product. However, its touchscreen was handling a significant amount of functionality—placing a heavy load on the user and device firmware. To create a more seamless experience, key features and interactions needed to transition from the device to the mobile app.

This required thoughtful iteration and a carefully designed user journey, ensuring a smooth interaction between the device and app. The result? A system that not only mirrors device controls when the device screen isn’t accessible but also enables easy organization of measurements into projects—making them readily available for future reference or effortless sharing with collaborators.

Most people see a companion app as just a way to update firmware or retrieve information—and while that’s true for the Sennses Pro, its potential goes far beyond that. The product strategy extends functionality, offering additional features and mirroring the device when connected for a more seamless experience.

Conceptually, it’s similar to a smartwatch, but the Sennses Pro is a multi-functional utility tool, adapting to different situations—or even accessories while on the job. Its real power lies in giving users the flexibility to interact with it in the way that feels most natural.

While features like login flows and sharing functionality are often taken for granted, they play a crucial role in the user experience for Robbox, ensuring a clear interaction was essential. This is especially true since many customers don’t have the time or patience for overly complex systems in the construction industry. In fact, this simplicity is one element that helped set the Sennses Pro apart from competitors that have struggled with usability.

You can see in the video, that when working together, the device and app feel magical. Today, the Sennses Pro has earned the trust of over 1,000 satisfied customers, with 5-star ratings as its most common review. This multi-functional, durable device combined with its seamless integration between hardware and app—effortlessly replaces multiple traditional tools while enhancing their functionality in the process.
