A faster, better way to take and monitor temperature.

ActivAngel is the simplest, easiest, and most intelligent way to continuously monitor temperatures for your entire family. Measure one child’s temperature or the whole family’s, all with a single tap on your phone or tablet. Real-time alerts keep you informed if a temperature gets too high - or too low. And ActivAngel is comfortable and long-lasting enough to use for an hour, a day, or a week.

Instant readings, accurately.

What good is a thermometer if you can’t trust it? ActivAngel uses the most accurate and efficient temperature sensors available to provide you with peace of mind.
A single tap is all it takes to see the current temperature. No accounts to set up or passwords to remember - it just works. Instantly.

Wear it and forget it.

Small, thin, and lightweight, ActivAngel is comfortable enough to wear for days at a time. Medical grade adhesive patches are safe for even the most delicate and sensitive skin.
