Symptom Diary App
The record your doctor keeps asking for
“How often does it happen, and where exactly?” is a hard question to answer from memory, especially when it is three different things. Log each episode when it happens: the symptom, a severity score, the body area and anything that might have set it off. Before an appointment, the per-symptom stats and the timeline answer the questions for you, whether it is your back, your stomach or a dizzy spell nobody can explain.

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.
From install to first entry in a minute
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.
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.
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.
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. Three complaints stay three lines, not one blur.
Where it hurts, every time
A body area on each entry, picked from a short list, so “pain” in the back and “pain” in the chest never end up in the same total. It is the second question every doctor asks.
Triggers in context
A Trigger field for your best guess, food, sleep, stress or a long day at the desk, sits on the same entry as the score, and values you have typed before come back as quick picks. Leave it blank when you have no idea; a guess is worse than nothing.
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 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, 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.
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.
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.
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.
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 across everything
Find an entry by title, note or value across every log, filter by date or location, and jump straight to it.
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 more than one thing going on who need to describe each 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 where it hurts are enough to make the record useful.
What the diary shows after a month
Frequency per symptom, average and worst severity, and which body areas keep coming back are exactly the figures a consultation runs on. Having them ready changes the quality of the appointment.
Triggers show up in the Trigger field and 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.

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 time how long a symptom lasts?
Yes. Start the timer when it begins and stop it when it passes, or fill in the length later. Hours affected per month is a number doctors find far more useful than “a lot”.
Can I share the diary with my doctor?
Show the stats and timeline on your phone, or export the log as a CSV file and send it — Settings → Export data, or the log card’s “…” menu for this log alone. Shared logs, where someone else sees the log live, are still in development.
What about migraines specifically?
If migraines are what you track, the Migraine log is built for exactly that: one condition, its attacks, the trigger as the category, and whether the medication helped. This diary is for when there are several different things to follow.
