Feedback, problems, or a product you would like added.

HydraCal is a one-person project, so replies may not be instant — but every message is read.

If you are unwell, please do not wait for a reply

This form is not a medical service and is not monitored urgently. If you are struggling to keep fluids down, or worried about your intake, contact your healthcare team. In an emergency call 999; for urgent advice call 111. If you have a 24-hour acute oncology helpline number, use that first.

Please don't include medical details you wouldn't want in an email — a description of the problem is enough.
