Scroll this blog back far enough and you'll find posts about sleep debt and HRV; you might even remember that Fulcra had a health app for a while. That app was a part of our journey to where we are today.

Fulcra is a user-owned context backend for AI agents that was originally the back-end for our health app. But, as MCP protocols landed, we were able to expose our internal tools to a larger market of users. Now, Fulcra stores anything allowing your real-world data to land in one place you own, and every agent you authorize to read and writes there.

So was there a pivot?

When we shipped the Context iOS app in January 2024, the launch post described it as gathering "health metrics, calendar events, locations, and more" into your Fulcra Data Store, and the same post pointed at the Life API so you could pull all of it into Python or a Colab notebook.

By that September, Fast Company covered us as one safe place to store and analyze your personal data, and by January 2025 my own podcast bio said the job was to empower AI to work with personal context.

We've been doing this from the beginning but in stages.

FAQ

Is Context still a health app? Context is the recorder, and it takes sleep and workouts alongside calendar events, location, files, and your own written annotations. Health records are one Data Type among many, and plenty of people run Fulcra without connecting a wearable at all.

Does an agent need my health data to be useful? No. Calendar, contacts, files, and meeting notes are enough for most of the coordination problems developers bring us, and access is granted per agent, so an agent gets what you point it at.
