Open at the foundation
Your data should have a life beyond the app it came from. Terasa is built on Open Wearables, with an open-source API that gives your apps, agents, and integrations a shared foundation to build on.
Your health data.
On your terms.
Terasa helps you do more with your wearable data. Use it with your own AI agent, a compatible health app, or something you build yourself. You choose what comes next.
Collected by your wearable. Useful beyond it.
Your history stays with you
Keep a record of your sleep, workouts, and daily activity. When you move to a new supported wearable, earlier readings remain available in Terasa.
Transparent scoring
We’re working toward community-built scoring algorithms you can inspect and apply to your own data. Understand how a score is calculated before deciding whether it’s useful to you.
Connect your own tools
Give your AI agent or a compatible health app access to your readings. Use it to explore patterns, ask questions, and understand changes in your habits.
Build what you need
Create your own apps, dashboards, and automations on top of your data. Start with a weekly summary or connect your readings to another part of your daily routine.
Managed for you
Terasa hosts the platform. Open it in your browser without installing software or running a health-data server yourself.
Control what you keep
Set how long Terasa stores your readings, and delete your health data when you choose. Manage both from your account settings.
