Your health data,
your terms.
The Cicada Ethos app turns the data your devices already capture into a steady monthly reward — and into research that benefits everyone. Connect once, choose what to share, get paid.
Pair every device, just once.
The first time you open the Cicada Ethos app, you link your health data sources. After that, everything is automatic — your daily heart rate, sleep, breath, and activity flow into the app in the background.
