HealthJournal helps you understand what's actually working for your health — from diet to supplements, sleep to workouts. Everything stays on your device, so you stay in control.
Connect your entries with your outcomes. See how your actions are affecting your energy, weight, pain levels, or other goals — over time.
HealthJournal runs local AI to extract trends, highlight correlations, and present them in beautiful, simple dashboards — without uploading your data.
Your journal lives in an encrypted file on your device. It's yours to keep, audit, and share — only if, when, and how you choose.
We believe the best way to care for your health is to own every bit of it. HealthJournal stores everything locally, in a format you can inspect, back up, and — soon — selectively share through a secure sovereign agent.
