How to keep a health journal
for your doctor.

Why a journal changes an appointment

A doctor's appointment in the UK lasts about ten minutes, and most of the questions in it are about time. When did it start? How often? Is it worse than last month? What have you tried? Memory is poor at exactly this: a symptom that was dreadful on a Tuesday in March becomes "a while ago" by June. A dated journal answers those questions in seconds, and the appointment moves on to what to do about it.

It also helps the person who cannot be in the room. If you look after a parent or a child, the journal is how the next carer, or the next doctor, knows what the last one saw.

What to write down

• Symptoms. The date, what it was, how bad it was on a scale you keep to (one to ten works), what made it better or worse, and how long it lasted. One line per event beats a long essay.
• Medicines. The name, the dose, when you took it, any dose you missed, and anything that felt like a side effect. Include things bought over the counter.
• Results. The number, the unit and the date, copied from the letter or the app your clinic uses. Leave the interpretation to the clinician; the journal's job is to have the number to hand.
• Appointments. Who you saw, why you went, what was said, and what happens next. Write it the same day, while the wording is fresh.
• Questions for next time. They arrive at odd hours. Written down, they survive until the appointment.

Keep it in order, not in a drawer

The record only works if it is dated and in one place. A photo of a rash is useful; a photo of a rash with the date, filed beside the entry about the itch, is evidence. Sort by body area as well as by date, so the story of one problem can be read through without the rest in the way. Keep the paperwork, clinic letters, prescription slips and referral forms, in the same place as the notes, so nothing has to be found on the morning of the visit.

The one page to hand over

Do not bring the whole journal. Bring a summary and hand it over at the start of the appointment. It should fit on a page and hold:

• Allergies, and how serious each one is.
• Ongoing conditions, and your blood type if you know it.
• Current medicines and doses.
• What has happened since the last visit, newest first, with dates.
• Your questions.

Mark it as your own notes, not a medical record. Clinicians read a page like this quickly and gladly; it is the difference between an appointment that starts with history-taking and one that starts with the problem.

Paper, a notes app, or a health journal app

All three work. They differ in how much work the sorting and the summary take.

Keeping it in	Good at	Falls down on
A paper notebook	Always works, nothing to set up, nothing to leak.	Searching, sorting by problem, sharing with a carer, and the one-page summary, which you write by hand each time.
The notes app on your phone	Always with you, searchable.	No dates on entries unless you type them, no sorting by body area, no export in a shape a doctor can read.
A health journal app	Dates every entry, sorts by area, keeps medicines and results beside the notes, and makes the summary for you. Can be shared with a carer.	Only as private as the app is built. Check how it stores your record before you trust it.

What to look for in a health journal app

• It works offline. A record you cannot open in a clinic basement is not a record.
• It is encrypted on the phone itself, and says so in plain words.
• You can export your own record, on the free plan, at any time. An app that holds your history hostage is the wrong app.
• Separate profiles for the people you look after, with a way to invite a helper and take that access back.
• No adverts and no selling of data. Advertising in a health app means selling what you wrote down.
• It says it is not a medical device. A journal records; it should not diagnose, score or interpret.

Where Biojrnl fits

Biojrnl is a private health journal for iPhone and Android, made in the United Kingdom by Biojrnl Ltd. It keeps entries by date and body area across 17 areas, medicines with doses ticked off, blood results, vaccinations course by course, appointments with a checklist before the visit, and the documents and photos that go with them. It works offline; the journal is an encrypted database on your phone, and cloud backup is a switch you choose to turn on, stored in the European Union. You can export your record on every plan, including the free one.

Visit Prep turns the record into the one page described above: allergies, conditions, blood type, recent appointments and entries, as a PDF to hand over. Family and Care plans add managed profiles for a parent or a child, co-managers you invite, and guest passes that show a sitter only what you choose, for the time you choose. There are no adverts, no AI reading the record, and nothing is sold. It is not a medical device, and it does not diagnose or interpret anything you record.

The free plan has no card and no time limit. Pro is £4.99 a month, Family £9.99 and Care £19.99, each about two months cheaper on a yearly plan. See what the app does, screen by screen, the plans side by side and how privacy works.

This guide is about keeping your own notes. It is not medical advice. If you are unwell, speak to a qualified clinician; in an emergency, contact the emergency services.
