Symptom Memo

"I don't feel well, but I can't explain exactly what's wrong." "I've had this pain before… haven't I?"
Symptom Memo turns those vague health concerns into clear, visual records.

◆ Two Easy Recording Modes
【Body Map Mode】
Tap anywhere on a human body silhouette to drop a pin on the exact spot. Switch between front and back views to precisely record where your discomfort is.
"The right side of my head hurts." "My lower left back feels heavy."
— Capture the exact location of symptoms that are hard to put into words.

【Symptom-Only Mode】
For symptoms like nausea or diarrhea where the focus is on the symptom itself rather than a specific body part. Record quickly without using the body map.

◆ Describe Your Symptoms in Detail
・Severity level (5 stages) to track how bad it is
・Symptom categories: Pain / Nausea / Fatigue / Itchiness / Discomfort / Other
・Duration: easily set from 15 minutes to 12 hours
・Possible causes: Lack of sleep / Stress / After eating / Alcohol / Post-exercise / Weather / Menstruation / Unknown
・Add your own custom symptoms and causes (up to 3 each)
・Free-text notes: add extra details about your condition

◆ Track Remedies & See What Works
After logging a symptom, record what you did about it — took medication, lay down, rested, applied heat or cold, drank water, visited a doctor, and more. Then log the result: Improved / Slightly improved / No change / Got worse.
"That medicine worked." "Applying heat made it better."
— Discover what remedies work best for you through your own records.

◆ Review & Discover Patterns
Select any recorded symptom to review data from the surrounding week.

・Daily Review: Pick a date and see all symptoms, remedies, and lifestyle data at a glance
・Heat Map: Visualize where symptoms cluster on your body over time
・Trend Analysis: Automatically detect patterns in timing and frequency for the same body area
・Remedy Effectiveness: See which remedies led to improvement and how often

◆ Doctor Visit Summary
Organize your symptom frequency, severity, location, and remedy results by time period into a clear summary you can show your doctor. Never struggle to answer "When did it start?" or "Where does it hurt?" again.

◆ Apple Health Integration — Compare Lifestyle Data
Connect with iPhone Health to compare lifestyle data between days with symptoms and days without.

・Sleep duration comparison
・Step count comparison
・Resting heart rate comparison

"On days with symptoms, I slept 30 minutes less." "I tend to feel worse on low-step days."
— Let data reveal insights you might otherwise miss.

◆ Calendar Overview
View your symptom history at a glance with a monthly calendar. Symptoms are color-coded by category, making it easy to spot health trends and review before doctor visits.

◆ Share Symptoms with Family & Partners
Simply send an invite link to easily share your recorded symptoms with family or your partner.
You can keep track of each other's health changes together.

◆ Built with Privacy in Mind
・Works completely offline — symptom data stays on your device only
・iCloud backup & restore supported — peace of mind when switching devices
・Reminder notifications after logging a symptom help you follow up
・No account registration needed — start using it right after download

◆ Perfect For
・Anyone tracking chronic headaches, back pain, or recurring symptoms
・Patients who want to clearly communicate symptom frequency and location to their doctor
