Step one · The device
Halo is small and screen-free. Clip it to a belt, a bra, or a waistband, wherever it disappears into your day. No buttons to press, no apps to open, nothing to remember. It notices three things:
Balance
How steady you are on your feet: the sway and rhythm of every step.
Movement
How much you're up and about: walks, chores, the garden, the stairs.
Vital signs
Heart rate and breathing at rest: the quiet background of your health.
Step two · Learning
There is no ideal score to chase. Over the first few weeks, Halo learns the pattern of your own days: how you walk to the kettle, how you sleep, how your heart behaves on a quiet afternoon.
From then on, it compares you only with you. A slow day after gardening is normal. The same slow day, every day, for two weeks? That's worth knowing about.
Your steadiness · twelve weeks
Your usual range
The last three weeks drifted below your range. Halo would mention it now, weeks before it becomes obvious to anyone.
Step three · Telling you
When Halo notices a change, it doesn't beep, flash, or frighten. It tells you what it saw and what you might do, the way a good friend would.
A change is a reason to ask a question, not a reason to stop living. Mention it to your doctor, check your shoes, mind the stairs.
Most days
“You're moving steadily today, same as your usual.”
Worth a look
“Your walk has been a little slower for two weeks. Worth mentioning at your next appointment.”
If you choose to share
“Ana sees: Mom had a steady week.” One line, once a week. That's all.
Privacy
Private by default
Everything Halo learns stays with you unless you decide otherwise. Nothing is shared automatically, not with family, not with anyone.
You hold the switches
Sharing is one switch per person, per thing. Turn it on for your daughter, off for everyone else. Change your mind any time.
Never sold, never ads
Your health information is not a product. We don't sell it, rent it, or use it to show you advertising. You can delete it whenever you like.
Questions
Do I need to be good with technology?
No. The device has no screen and no buttons. The app shows one page at a time, in large type, in plain words. If you can read a postcard, you can use Halo.
Is this an emergency button?
No, and that's the point. Emergency buttons help after something happens. Halo works before: it helps you notice changes early so there's less need for the button at all.
Will my family be watching me?
Only if you choose, and only what you choose. Most people share a single weekly summary line. Location is off by default and stays off unless you turn it on.
How often does it charge?
About once a week, on a small stand by your bedside. Halo reminds you gently the day before it's needed.
Does Halo replace my doctor?
Never. Halo helps you arrive at your doctor with better questions and a clearer picture. It's information, not diagnosis.
