Free is not the same as ready.
Your calendar knows when you're free. It has no idea when you're sharp.
Your calendar sees only open slots. It can't see that you slept only four hours.
So the meeting that matters most lands when you're weakest. Deep work gets the leftovers and your best hours go to scheduling emails.
Three steps. Then signal runs in the background.
1. Connect. Link your calendar and your wearable data.
2. Set your priorities. Tell Signal what matters most: key meetings, focus time, training, rest.
3. Let it plan. Signal considers your priorities and places everything in your best windows, adapts each day, and coordinates with everyone involved.
Your ideal schedule. Managed for you.
Right time
Key meetings and deep work land in your strongest windows, adjusted every day as your recovery changes. You do your best work when it counts.
No effort
Signal negotiates and reschedules with everyone for you. No threads, no polls, no "does Thursday work?"
No explanations
Others see a time slot, never the reason. You don't have to justify a "no" or a "later."
Strongest Data Privacy
Your body stays out of your calendar.
Your health data stays in your personal context. It is used to plan your day, never to inform anyone else.
Everyone you meet with sees one thing: free or not free. No scores, no reasons, no hints.
Private by design, not by setting.
Who it's for
