Rate, resting rate, variability, rhythm, sample age, and the confidence behind every reading.

HUMAN
SIGNAL
Your body is already transmitting.
A personal telemetry receiver that turns Apple Watch and Health data into calm, baseline-aware observations—without goals, grades, guilt, or fake certainty.
Not a fitness app. A receiver.

RECEIVE SIGNAL
00 / THE IDEA
Your Watch has sensors.
Fitness apps turn them into a scoreboard.
Human Signal turns them into a receiver.
01 / SYSTEM SCAN
The body is a living machine.
Heart, sleep, movement, temperature, respiration, and recovery are not assignments. They are channels in a signal that becomes meaningful over time.
Sleep
Duration, continuity, timing, and how the latest night compares with your own recent range.
Input channel / Not a bedtime scoreMovement
Steps and activity can explain the system without becoming a goal the system demands.
Input channel / Not a ringAvailable systems
Temperature, respiration, oxygen, ECG, and future sensors—only when the hardware provides them.
Capability-aware / Evidence first02 / CATEGORY ERROR
This is not another fitness app.
Most wearable software turns the body into homework. Human Signal is designed for curiosity, context, and pattern recognition.
FITNESS APP
- Question
- Did you do enough?
- Reference
- A target
- Output
- Scores + rings
- Behavior
- Push + correct
- Failure state
- You are behind
HUMAN SIGNAL
- Question
- What changed?
- Reference
- Your baseline
- Output
- Observations + evidence
- Behavior
- Notice + remember
- Failure state
- No recent signal
You are not behind.
You are transmitting.
03 / ENERGY RESERVE
A battery metaphor without the fake percentage.
Human Signal does not pretend one sensor can prove that a person has “23% energy.” Energy Reserve is qualitative, baseline-relative, and accompanied by the signals that informed it.
- Below your recent range
- Within your recent range
- Above your recent range
- Baseline forming / Limited signal
04 / OPERATING PROTOCOL
Restraint is a feature.
-
01
Observe first.
Read only what is available. Show freshness, source, and missing data. Never decorate uncertainty as certainty.
-
02
Interpret second.
Wait for a personal baseline. Compare the human with the same human—not a generic ideal.
-
03
Advise last.
Human Signal never diagnoses. It presents observations and lets the person add context or seek expertise.
05 / SIGNAL ARCHIVE
The body has logs.
Read them.
Over days and months, observations become a private system history. Add context—travel, illness, a late night, a hard conversation—and patterns become easier to recognize without turning life into a streak.
SIGNAL ARCHIVELOCAL / PRIVATE
06 / TRUST MODEL
Your body is not content.
The prototype reads Apple Health data locally and read-only. No workouts written. No health-data server. No advertising profile. No subscription required to understand your own signal.
The receiver should know as little about your identity as possible—and enough about your baseline to be useful.
07 / CURRENT TRANSMISSION
Prototype receivingBuilt on the Watch.
Tested on a human.
Human Signal is an active UFO Studios field test for Apple Watch. The working prototype receives heart and sleep signals, forms a seven-day baseline, and produces evidence-led observations on a real Series 7.
It is not publicly available yet. The next phase expands the Signal Archive, context capture, confidence language, and additional hardware-aware channels.
