About this list
These tools are built and maintained by their own authors. We list them to help you find them. A listing is not an endorsement or a clinical check, and the short notes describe what each tool is, not how good it is. Check any number against the source guideline before it affects care. Builders: to correct a listing, add a screenshot or ask to be removed, use Suggest a correction on your tool's card.
