On the Session tab, the client watches a smooth-moving target (a glowing ball travelling left↔right). You drive it; the client's screen mirrors it automatically — they don't click anything to receive it.
- Start / Stop / Reset — Start begins the motion, Stop pauses it, Reset clears the pass count and timer and re-centers the ball.
- Passes — counts each left-to-right sweep. Turn on Limit to set a cap; the session auto-stops when it's reached.
- Timer — set a countdown (30 seconds up to 30 minutes); the session stops on its own at 0:00.
- End Session — stops the session and, on a paid plan, moves you to the post check-in.
Every control here is yours — the client only ever mirrors what you set.
