Continuous monitoring.
Uninterrupted rest.
Temperature monitoring that lets rest continue.
A wearable temperature monitor designed to reduce the disruption of repeated manual checks. Connect tempo to the app, set the range that works for you, and receive an alert when readings move outside it.
The overnight record
A full night, at a glance.
tempo tracks continuously while someone rests. You see the whole night as one line — with your threshold marked, and the moment attention was needed drawn plainly, in words as well as colour.
Overnight temperature · 22:00 – 07:00
How it works
Set it once. Let it keep watch.
Connect tempo
Pair the wearable with the CASEL app over Bluetooth. Setup is quick, and there's nothing to configure that you don't want to.
Set your range
Choose the temperature range that works for you. tempo tracks continuously in the background — no repeated manual checks.
Get an alert
Receive a clear alert only when a reading moves outside your range — so you can step in when it matters, and rest when it doesn't.
Placement
Same sensor, same placement — for every age.
Children
Low profile, nothing to knock or pull at during sleep.
Adults
Discreet under clothing, and it stays put through a working day.
Older adults
No screen to read, no button to press. It simply reports to whoever is helping.
Same sensor, same placement, three ages — carried by CASEL's casting rule: care is not assigned to one group.
In the app
Three screens, nothing else to learn.
The live reading, with the alert stated in words as well as colour.
The night as a record you can hand to a clinician.
One household, one app — a child, a parent, yourself.

What tempo is. tempo monitors temperature and supports care. It does not provide care itself, is not a substitute for professional medical assessment, and makes no claim to prevent illness or guarantee sleep.
