HealthZena · App Releasing Soon

Know how they're doing, before they have to tell you.

Zena Intelligence is two watches built to work together. One for the patient. One for the person watching over them. Vitals, location, and health updates, shared in real time.

How It Works

One system, two watches

Zena Patient stays on the person recovering. Zena Guardian stays with the person who needs to know how they're doing. They talk to each other automatically.

01

Zena Patient Is Worn

The patient wears their watch like any other. No apps to open, no buttons to press.

02

Vitals Stream Automatically

Heart rate, movement, and location update continuously in the background.

03

Zena Guardian Receives It

A parent, spouse, or caregiver sees the same data live, on their own watch or the app.

04

Alerts Fire Instantly

A fall, an irregular heart rate, or an unexpected location change sends an alert right away.

Zena Intelligence

Two watches, one connected system

Zena Patient goes on the person recovering. Zena Guardian goes on the person who needs to know how they're doing. Together they close the gap that usually opens the moment someone leaves the hospital.

Zena Patient

Worn by the person recovering. It reads what's happening in the body and sends it out automatically. Nothing to open, nothing to log.

  • Continuous heart rate, blood oxygen, and fall detection
  • Live location, so a wrong turn or a long stillness gets noticed
  • One tap SOS that reaches Zena Guardian instantly
  • Medication reminders that vibrate on the wrist, not just the phone

Zena Guardian

Worn by the parent, the spouse, the adult child. Whoever is the one who actually needs to know. It shows the same data Zena Patient is reading, live, without a phone call.

  • Real time vitals from the paired Zena Patient watch
  • Location on a map, updated continuously
  • Instant alerts for falls, missed medication, or irregular readings
  • A daily summary, so you know without having to ask

What It Tracks

Built for the things that actually matter

Every reading a Zena watch takes goes to both watches and the app at the same time. No manual entry, no separate check ins.

Heart Rate & Vitals

Continuous monitoring of heart rate, blood oxygen, and resting patterns, updated in real time.

Heart RateSpO2

Live Location

GPS tracking that updates continuously, visible to Zena Guardian on a live map.

GPSLive Map

Fall Detection

Sudden impact and unusual stillness trigger an automatic check in, and an alert if there's no response.

Auto AlertSafety

One Tap SOS

A single press sends an alert straight to Zena Guardian, with location attached.

EmergencyInstant

Medication Reminders

Reminders vibrate on the wrist, and a missed dose is flagged to Zena Guardian automatically.

RemindersAdherence

Battery That Lasts

Built for multi day wear without needing to think about charging every night.

Multi Day

Water Resistant

Built to be worn in the shower, washing dishes, or caught in the rain, without a second thought.

Durable

Daily Health Reports

A short summary sent to Zena Guardian every day, so nothing requires a phone call to find out.

Reports
The Zena App

Everything both watches see, in one place

The app mirrors what's on Zena Guardian, so anyone in the family with access can check in without needing to wear the watch themselves.

Live vitals

Heart rate, blood oxygen, and activity, updated continuously from Zena Patient.

Location on a map

See exactly where they are right now, and get notified if they leave a set area.

Alert history

Every fall, missed medication, or SOS press logged, with a timestamp and what happened next.

Multiple guardians

Add more than one family member. Everyone sees the same data at the same time.

Why We Built This

The gap opens the moment someone leaves the hospital

A patient gets discharged, and from that point on, nobody outside the house knows how they're actually doing. We built Zena Intelligence to close that gap with hardware, not paperwork.

Built to Notice

Falls, missed medication, and irregular vitals get caught automatically, not after someone finally calls to check.

Privacy First

Data moves between Zena Patient, Zena Guardian, and the app, and nowhere else. It's built for the family, not for advertisers.

Made for Real Families

We tested this with actual patients and the people worried about them, not in a lab. Central Florida first, then wherever it's needed next.

Questions

Frequently asked questions

What's the difference between Zena Patient and Zena Guardian?
Zena Patient is worn by the person recovering and reads vitals, location, and activity. Zena Guardian is worn by the family member who needs to know, and shows the same data live. They're paired to each other out of the box.
Do I need both watches, or can I buy one?
You can start with just Zena Patient and monitor through the app instead of a second watch. Zena Guardian is there if you want the same alerts on your own wrist without checking your phone.
How does it detect a fall?
Zena Patient reads sudden impact and unusual stillness. If it detects a possible fall, it prompts the wearer to confirm they're okay. No response within a short window sends an automatic alert to Zena Guardian and the app.
What happens if the watch loses signal or dies?
Zena Guardian gets notified immediately if Zena Patient goes offline or the battery drops critically low, so a gap in monitoring is never a silent one.
Is my data private?
Vitals and location data only go to the watches and app you pair together. It's not sold, shared with advertisers, or used for anything outside your own account.
When does it launch, and where?
We're releasing soon, starting in Central Florida with early access users, before opening up more broadly. Join the early access list to get a spot in the first batch.

Where HealthZena stands right now

We'd rather be straightforward about this than dress it up. Here's the real picture: what the hardware costs today, what we're planning to charge, and what we think this is worth at this stage.

Pre‑revenue
Current Stage
Software and hardware, both still in prototype
$500
Complete Set
Patient Watch $300, Guardian Watch $200
$25/mo
Infrastructure Today
Expected to reach about $600/mo by August 2027
$50
Prototype Hardware Cost
Before the enclosure, strap, software, and certification

We're building on real hardware, not a mockup

The board we're prototyping on costs about $50 a unit. That number doesn't include the HealthZena software, a custom back enclosure, buttons, the strap, final industrial design, packaging, or manufacturing and certification. Right now this hardware is a development platform, not the retail product, and we're upfront about that with anyone looking at the numbers below.


What we think this is worth today, and where it could go

HealthZena is pre revenue. We don't have customers or a sales history, so the usual ways of valuing a company off revenue don't really apply yet. Based on where things stand right now, the concept, the site, the software work so far, the hardware prototype, and the waitlist we've already built, a reasonable estimate is somewhere between $150,000 and $400,000, with $250,000 as a fair starting point for a conversation. This is an early, informal estimate. It hasn't been independently appraised or confirmed by the market.

  • $250,000

    Current estimate

    Midpoint of a $150,000 to $400,000 range, based on where development stands today.

  • $500,000 to $1.5 million

    Working prototype

    A demonstrated monitoring system with a functioning app, patient watch to guardian watch.

  • $1 million to $3 million or more

    Early traction

    Real waitlist growth and a successful product demonstration to early users.

  • $2 million to $5 million or more

    Paying customers

    Recurring revenue and validated technology in real households.

  • $5 million to $15 million or more

    Scaled revenue

    Strong growth, regulatory progress, and a defensible position in the market.

These are potential ranges tied to milestones we haven't hit yet, not promises about what this will be worth.


What sales could look like at scale

At the planned $500 per complete set, here's roughly what different volumes would mean before any costs come out.

$500,000
1,000 Sets Sold
$5 million
10,000 Sets Sold
$50 million
100,000 Sets Sold

Gross sales, before manufacturing, shipping, payment processing, taxes, returns, support, infrastructure, regulatory work, and marketing.


It's not really about the watches

The hardware is the entry point. The value is in what happens after someone puts it on.

  1. Wearable hardware collects health data
  2. Health data feeds into HealthZena software
  3. Software runs it through analysis built to catch trends
  4. Trends turn into a notification the right person actually sees

As we grow, what protects that position is the software itself, the algorithms behind it, what we learn from real usage, the user experience, any healthcare partnerships, and eventually intellectual property.


What this estimate doesn't assume

  • No revenue or paying customers yet
  • No clinical validation completed
  • No FDA clearance or approval
  • No patents filed
  • No large scale manufacturing in place
  • Not yet an established medical device
  • Sensor accuracy not yet proven at commercial scale
  • These are future milestones, and real risks, not assumptions baked into today's number
