Health Tracker is a private health diary for anyone who needs to tell a doctor what actually happened, and when. Log symptoms, food, medication and more, then take a clear report to your appointment.
Your entries are stored in the private application folder of your own Google Drive - an area only this app can open - with a copy on the device so it works offline. You sign in with your own Google account so the app can reach that folder. There is no account with us, no server of ours in between, and nothing about you reaches us unless you choose to email us.
Built for people managing an ongoing condition, working through an elimination diet, preparing for a specialist appointment, or simply trying to answer "how long has this been going on?" with something better than a guess.

📄 Reports For Your Appointment
Generate a factual summary of any window and export it as a PDF. It carries the figures, the
statistics behind them, and every en clinician can check one against theother. Ten minutes with a doctor goes further when the history is already on paper.
🤖 Optional AI Features
If you supply your own Google Gemini API key, the app can write two kinds of report from your log. The
summary describes what was recorded, pattern analysis suggests what thedata could point to, stating clearly that every explanation is unverified. It can also describe a meal
photo and estimate calories for food
The key is yours, and requests go frgle. Before the first one, the appshows exactly what is sent and asks you to agree, and nothing is ever sent unless you press the
button. Readings imported from Healtests unless you allow them. With afree-tier key, Google may use what you send to improve its products. Anything the AI writes has a
"Report a problem" link. Leave the kimply stay off.
