A signal is the whole idea: a hygienist taps "ready," it lands on the doctor's wrist, and it clears when the check is done, and it works both ways, so the doctor can page all assistants or the front desk just as easily. It carries only room, type, sender and time.
Sign up with just an email and your office type, then a 2-minute setup assistant walks you through the rest: name your practice, add rooms (numbered or custom names), add staff with their roles, and customize your preset ready messages. It ends with a sign-in link for each room's computer and an activation link for each employee's phone. Open the link, and that device is signed in as that room or person.
Signals arrive ordered by priority, then by who's waited longest, with actionable push: On my way and Done, right on the wrist. No watch? The same queue lives on their phone and any office PC.
A signal carries a staff name, room name, signal type, and timestamp. That's all it needs to get the right person to the right room.
