## What is Mimu?

[What is Mimu?]

An AI alter ego that writes your diary for you, every single day.

You want to journal but can't keep it up. You're too busy to reflect. Mimu solves this -- your alter ego stays by your side all day, observing and recording your life.

This is not a chatbot. It's a new kind of journaling where "your other self" writes for you.

[A Day with Mimu]

- Morning Greeting
Your alter ego greets you each morning with words just for you. Share how you're feeling today.

- Whispers & Inner Voice
Throughout the day, whisper your thoughts. Your alter ego responds with an "inner voice" -- not a chat, but an internal dialogue, like talking to yourself.

- Nightly Diary
At the end of each day, your alter ego writes a diary reflecting on your mood, whispers, weather, and more -- weaving it all into one story.

[Grows with You]

Your alter ego builds memory over time. Day 1 entries are simple. Month 1 entries show real insight. It notices patterns you never saw:

"You tend to feel low on Mondays."
"Days when you whisper more are actually your happier days."

[Uniquely Yours]

Customize the name, personality, and tone. MBTI, zodiac, and personality traits shape how your alter ego thinks and writes. No two are alike.

## Version history (last 2 releases)

### 1.0.1 — 2026-05-10

Weather icons now render correctly in your journal. The moment you grant location access, today's weather is fetched automatically for that night's entry.

What's improved:
- Weather icons display reliably now, so each day's mood and weather stay together in your reflections.
- The first time you grant location access, weather is fetched right away — no waiting for tomorrow.
- Settings > "Auto-fetch weather" shows the most recent fetch result so you can confirm it's working.
- Polished display details across Japanese, English, Korean, and Simplified Chinese.

Fixed:
- Subscription state is now consistently respected across all alter-ego features, so trial and post-cancellation behavior is clearer.
- The screen now communicates clearly when you're not eligible for the free trial.
- Various small bug fixes and overall stability improvements.

### 1.0 — 2026-05-06

No release notes.
