Symptom Diary App
The record your doctor keeps asking for
“How often does it happen?” is a hard question to answer from memory. Log each episode when it happens: the symptom, a severity score, how long it lasted, and anything that might have set it off. Before an appointment, the per-symptom stats and the timeline answer the questions for you.
What, how bad, how long, and what came before it.
Also called a symptom tracker, symptom journal or pain diary.

In the app
What the Symptom Diary log looks like
A real screenshot, not a mockup: the stats up top, a breakdown per symptom, the streak and the calendar heatmap, with the entries below. Every number comes from the entries you add.
How it works
From install to first entry in a minute
1
Pick “Symptom Diary” during setup
The log is created with the variables above and a few example entries so you can see how it works. Clear them with one tap.
2
Log as you go
Tap plus, fill in what you have, save. Timer, location, notes and photos are there when you want them, hidden when you don’t.
3
Let the stats accumulate
Average severity sits on the log card, with the rest one tap away. Set a goal if you want a nudge.
Why this log
Built for the way you actually do it
Per-symptom breakdown
Mark “Symptom” as tracked individually and the stats screen shows each one: how many episodes, average and worst severity, when the last one was.
Duration with a timer
Start the timer when it begins, stop it when it passes. Total hours affected per month is a number doctors find far more useful than “a lot”.
Triggers in context
Notes about food, sleep, stress or weather sit on the same entry as the score, so the pattern behind the episodes has a chance to show itself.
Everything else in the app
Not just a form. A logbook that thinks with you.
The Symptom Diary log is one log among many you can keep. Every one of them gets the same tools.
AI analysis
AI reads the pattern for you
Tap the bulb on Symptom Diary and get a plain-language read of your trends, what changed recently, and a suggested next goal, built only from your own entries.
Goals
Goals, streaks and reminders
Set a target like three times a week, watch the rolling progress bar, keep a streak, and get a reminder at the time you actually log. The app learns that time from you.
Calendar
A calendar heatmap per log
Every log has its own month view showing which days you logged. Gaps are obvious, consistency is visible, and one tap opens that day's entries.
Rounds
Several symptoms in one entry
One entry can hold a round per symptom, each with its own values, and the stats break them out separately.
Attachments
Photos, sketches, voice memos
Attach a photo, draw a quick sketch, or record a voice note on any entry. They stay with that entry and come back on every device you sign in on.
Map
Every entry on a map
Drop a pin or search for the place. Each log has a map view of everywhere you logged, and saved places open directly in Google Maps.
Search
Search across everything
Find an entry by title, note or value across every log, filter by date or location, and jump straight to it.
Privacy
Yours, offline first
Entries save on your phone first and sync when you sign in. No account needed to start, no feed, no one else sees your data.
Who keeps a symptom diary
People with recurring headaches, migraines, stomach issues or chronic conditions who need to describe frequency and severity accurately, anyone going through a diagnosis where the doctor has asked for a record, and carers tracking symptoms for someone else.
The diary is fast on purpose. When you feel bad you will not fill in a long form; a symptom, a score and the timer are enough to make the record useful.
What the diary shows after a month
Frequency per symptom, average and worst severity, and total hours affected are exactly the figures a consultation runs on. Having them ready changes the quality of the appointment.
Triggers show up in the notes when they show up at all: a food, a sleep pattern, a stressful week. The diary does not draw the conclusion, but it makes drawing one possible.

Questions
Frequently asked
Is this a medical device?
No. It is a diary. It does not diagnose or advise; it makes your own record accurate so a professional can do that job with better information.
Can I track medication and dose?
Yes. Add a text variable “Medication” and a number variable “Dose” with the unit, and every episode can record what you took.
Can I share the diary with my doctor?
Today you show the stats and timeline on your phone. Shared logs and an export are in development, and this is one of the use cases driving them.
What about migraines specifically?
This log works as is. Set the symptom to “Migraine” and add variables such as “Aura” or “Trigger” if you want them tracked individually.
