## What is Yorusan?

■ 60 seconds before bed. Just 3 lines.
Yorusan (Japanese for "night + three") is the smallest journal you'll ever keep — built for people who never manage to keep one.

Every night, write exactly three lines:
1. The worst thing about today
2. The best thing about today
3. Tomorrow's goal

Vent the bad, end on the good, look ahead. This simple order — popularized by the Japanese bestseller "The 3-Line Diary" — clears your head so you fall asleep lighter.

■ Weekly and monthly reports (free, built on your device)
Your three lines quietly add up. Yorusan turns them into weekly and monthly reports:
- A summary of the period and your mood trend
- Your body's rhythm, seen through sleep and heart data
- Streaks and entry counts at a glance
Every report is built entirely on your iPhone — nothing is uploaded anywhere. Every feature is free, with no limits.

■ Never stare at a blank page
Pull today's photos, places, and workouts straight into your entry with iOS Journaling Suggestions (iOS 17.2+). On iOS 18+, your logged State of Mind pre-fills today's mood.

■ Health, read-only
Connect Apple Health (sleep duration, resting heart rate, HRV) to make reports richer, plus a daily "rhythm score" at a glance.
- Read-only: Yorusan never writes to Health
- Not a medical device: no diagnosis, ever

■ Built to stick
- One entry a day, three lines, nothing more
- Streak counter
- A gentle bedtime reminder
- 14-day mood chart

■ Privacy first
- Everything stays on your device — there is no developer server
- Your diary text and Health data are never used for advertising
- Your diary text and Health data never leave your iPhone

■ Pricing and ads
- Every feature is free. There is no subscription
- A banner ad appears only at the bottom of the History and Reports tabs — never on the writing screen, the edit screen, or Settings
- A one-time "Remove Ads" purchase (¥100) turns ads off for good. No auto-renewal
- If you ever bought the old "Yorusan Premium" subscription, your purchase history is detected automatically and ads stay off permanently — feel free to cancel the subscription

Start tonight. Three lines is all it takes.
