Three gauges
Quick checks on your wrist.
Three simple scores help you see how your day is going. The app uses soft liquid screens that feel calm and easy to read.
Zen
See how calm your body looks.
Zen helps you spot when your body seems steady, tired, or a little stressed.
Temp Trend
See your temp trend.
Temp Trend shows how your temperature pattern looks next to what is normal for you. It is not a fever test.
