See weekly patterns

Look back at your week with charts that bring your records together.

Reminders when you want them

Turn on a daily reminder. Notifications appear on your device without showing health details.

A few notes today. More context tomorrow.

It can be hard to remember how you felt a few days ago. Keeping bowel habits, water intake, and food notes together gives you a record to look back on.

Remember more than the unusual days

A short daily entry lets you look back at ordinary days too. You can compare your records without relying on memory alone.

See your routine in context

Keep food and water notes alongside your bowel and urine records. Seeing them together can help you notice what changes around the same time, without assuming one caused the other.

Bring your own observations to the conversation

If you discuss a concern with a healthcare professional, your notes can help you describe when you noticed a change. A record adds context; it does not give you a diagnosis.
