Display Board
Enterprise FeatureTurn any screen into a workout command center
When a timer is running, the room sees exactly where they are in the workout via Apple TV mirroring and Google Cast. When it isn't, the same screen becomes a branded board for your gym — no extra hardware required.
Apple TV mirroring & Google Cast
Send big, legible timing — countdowns, round counters, and phase colors — to any screen via Apple TV mirroring and Google Cast.
Idle-screen announcements
Between sessions, show class schedules, promotions, and member shout-outs.
On-brand displays
Match your studio's colors and identity so every screen reinforces your brand.
