HoopBoard by SB Embedded Systm

HoopBoard turns any Android TV or tablet into a live basketball scoreboard, controlled wirelessly from a phone — no extra hardware, no cables across the court.

One app, three roles, same WiFi network:
• Scoreboard — put it on the big screen or an Android TV. Shows the score, game clock, shot clock, fouls, and period, and sounds the horn.
• Console — the scorekeeper's phone. Tap to update scores, fouls, and the period, start/pause/reset the clocks, rename teams, and sound the horn manually — every change appears on the big screen instantly.
• Display — an optional second screen (another TV, a tablet at the scorer's table) that mirrors the scoreboard read-only, so as many people as needed can follow along. Everything runs over your local WiFi — connect the console to the scoreboard's on-screen code or IP and go. Clocks run drift-free directly on the scoreboard, so the display
Stays accurate no matter how many devices are connected or how the network behaves.

Built for gyms, schools, and rec leagues that want a proper-looking scoreboard without buying dedicated hardware.
