I’m working on Reflect [0], it’s a private self discovery and self experimentation app. You can track metrics, set goals, get alerted to anomalies, view correlations, visualize your data, etc.

Very cool app. Is there a way to periodically import from a Google Sheets spreadsheet? I track a bunch of things there on a daily basis and would love to have those pulled into this application.
