HerSensi tools
Useful tools that organise the problem—not diagnose you.
Calculators, trackers, comparison helpers and decision-support flows built to make the next step clearer. The most useful result is often a better question, not a label.
Private by default
Tool inputs are designed for in-browser use. They help you organise your own information without pretending a calculator can determine a medical cause.
Every tool now includes a worked example, limitations and next reading.
Higher-risk symptoms route back to professional care instead of false certainty.
