The Challenge

Traditional ball machines don't provide data, customization, or flexibility. Players cannot easily manage training sessions or track progress over time. Coaches need tools to manage multiple athletes in one platform.

Business Goals:
  • Deliver an integrated solution where the machine + mobile app work hand-in-hand
  • Allow users to create accounts, manage profiles, and track sessions seamlessly
  • Enable coaches to add multiple student athletes, assign drills, and monitor their progress in real time
  • Make Wolley not just a machine, but a digital coaching platform
