Your skin temperature can be flattened by one cooling break. Your core temperature can't.
CT1 is a smart band built around a single idea: the most dangerous rise in body temperature happens before you feel anything. It measures core temperature continuously, learns your own daily rhythm, and turns your body state into colour — so you know where you stand without looking at a screen.
Two temperatures. Two very different risks.
Most wearables report skin temperature. It is easy to measure and almost useless at the moment it matters most: as sweat evaporates, skin temperature drops while core temperature keeps climbing. The most dangerous window is exactly the one that gets hidden.
CT1 reports core temperature — the value that actually maps to heat stress and fever risk. Wrist skin temperature is only one input. Heart rate, heart-rate variability and ambient conditions feed the same estimate.
Read your body without looking at it
Two emissive arcs sit above and below the dial. One value drives both colour and vibration, so the state is always at the edge of your vision.
| Level | Colour | Light | Vibration |
|---|---|---|---|
| Normal | Green | Low steady or slow breathing | None |
| Mild | Yellow | One short flash, then slow breathing | None |
| Moderate | Orange | Two short flashes, then medium breathing | Double pulse, repeated |
| Severe | Red | High-frequency flashing | Continuous escalating pulses |
Safety is not a user setting. The red alert is enforced by firmware and cannot be switched off in the app. From decision to red light and vibration: under 3 seconds.
Four signals. One personal baseline.
CT1 does not compare you to a population average. It learns your circadian temperature rhythm first, then judges what counts as abnormal — because the same reading can be perfectly normal for one person and drifting for another.
- IR temperature — wrist skin temperature, one base input
- Heart rate & HRV — PPG signal and RMSSD, reflecting cooling load
- Ambient temperature & humidity — rates heat exposure
- 3-axis accelerometer — activity and wear state, used to reject noise
All four feed one core-temperature algorithm, developed in joint R&D with a medical university.
One wear, three jobs
Heat-stress protection — For outdoor and high-heat work: construction, sanitation, logistics, inspection. Heat load accumulates long before symptoms appear. CT1 tells you which level you are at, not just that you are hot.
Fever screening at home — For older adults, children in care and people recovering from illness. Fever usually shows up before symptoms do. You stop having to remember to measure.
Women's health — Long-term basal temperature rhythm, cycle prediction and ovulation windows, with the temperature curve laid over the calendar. The rhythm charts itself.

Important — please read
CT1 provides health reference and trend monitoring. It is not a medical device and does not diagnose, treat or prevent any disease. Cycle and ovulation predictions are based on the temperature method and historical cycles; they are for reference only and must not be used as contraception or as a medical basis.
The core-temperature algorithm builds a personal baseline from your profile — sex, age, weight, resting heart rate and resting temperature. Enter these accurately: an error of 0.5 °C shifts every subsequent reading and alert by the same amount. Your first 3–7 days are a baseline-learning period; wear the band as continuously as possible during it.
