Track any health metric.
See your trends. Own your data.
A free health metrics tracker that runs entirely in your browser. No account. No upload. Your data never leaves your browser — unless you export it.
Works offline once loaded. Nothing to install.
Any metric, not just templates
Weight, blood pressure, sleep, mood, energy — or that one thing only you track. Define custom metrics with your own units and log daily readings in seconds.
Set up metrics →A dashboard that shows trends
Every metric gets a chart. Spot drift over 30/90/180 days, compare against your own baseline, and see which high-value days line up with the days you flag.
Open dashboard →Your data, your device
Everything is stored in your browser — no account, no upload, no analytics on your numbers. Export a full backup as JSON or CSV anytime. We can't see your data even if we wanted to.
