Now imagine a different approach.
Instead of filling in tables every day or choosing symptoms from long lists, you could simply describe in your own words what you noticed that day.
For example:
“I have almost no appetite today. After eating, I feel heavy for a long time, and I didn’t sleep well last night.”
The system could ask a few short follow-up questions, save this information together with data about your menstrual cycle, and over time help you identify recurring patterns in your own records.
This would be a tool for observing and understanding your own wellbeing, not a medical diagnostic tool or a substitute for a doctor.
