We’re working on a privacy-focused iOS app that enables you to track anything. It’s called Reflect. The app enables you to answer questions like “how does meditation affect my mood” or “how does this new supplement intervention affect my sleep”. We already support detailed visualization and correlation between all of the metrics you track and are working on some very exciting features to make self-guided discovery even easier.
Here is the link to the app: https://apps.apple.com/us/app/reflect-track-anything/id64638...
