What this app is not.

This app does not diagnose anything

It records what you put into it and adds it up. Nothing here is a medical opinion, and no number it shows you means you do or do not have any condition. PotsLog is not a medical device, has not been evaluated by any medicines or devices regulator, and is not intended for the diagnosis, treatment, cure, mitigation or prevention of any disease.

The standing test is not a tilt table test

It is a home measurement, taken by you, without supervision, on equipment nobody calibrated. It is genuinely useful to your clinician as a record of what happens on ordinary days, in your own home, over weeks — which is precisely what a single appointment cannot show them. It is not the clinical investigation, and it cannot replace one.

A reading it produces can be wrong for reasons that have nothing to do with you: a watch that lost contact, a count taken while you were talking, a phone whose clock drifted, a test done after coffee or in a warm room. Read the line, not the point.

Targets come from your clinician, never from the app

Fluid and salt figures in PotsLog are the ones you were given. The app will never suggest a number, raise one, or tell you that you are behind on it. It does not know your kidney function, your blood pressure medication or your history, and a salt target set by software that knows none of those things would be dangerous rather than helpful.

The same is true of medication. PotsLog records the doses you told it about, at the times you set. It does not check interactions, does not know your prescription, and must never be used as the authority on what to take or when.

Reminders can fail, and you should not depend on them

Dose reminders are a convenience. Phones restart, batteries die, notification permissions get revoked, and operating systems defer alarms to save power. The app degrades quietly when that happens rather than pretending otherwise, but the consequence is the same: if a dose genuinely must not be missed, do not let this app be the only thing standing between you and missing it.

The report is a record, not an assessment

The doctor report summarises what you entered over a window you chose. It does not interpret, score, stage or triage anything, and the patterns it surfaces are observations about your own entries rather than findings about your health. Take it to an appointment as a starting point for a conversation with a person who can examine you.

If something is wrong, contact a person

The app will not tell you to seek care and will not decide that for you — deliberately. Software that issues warnings about your heart rate would be making a clinical judgement it has no business making, and would be wrong often enough to be either frightening or ignorable. Neither is a good outcome.

So the responsibility stays where it belongs. If you are worried about a symptom, an event or a reading, speak to your clinician or your local emergency service. Never delay seeking medical advice, or disregard advice you have been given, because of something you saw in this app.
