## What is Muon?

Speech, made readable.

Muon sits between Voice Memos and meeting transcription services. Record meetings, lectures, and memos—the moment you stop recording, AI gives you a readable transcript and summary. Designed with deep integration across Apple's ecosystem: Apple Watch, Action Button, Live Activity, Lock Screen.

■ Key Features
・High-accuracy AI transcription
・AI-generated summaries that extract what matters
・Recording from Apple Watch
・Live Activity (Lock Screen and Dynamic Island)

■ Built for the Apple Ecosystem
Tap your wrist to start recording. Tap again to stop. One press of the Action Button starts a new recording. Elapsed time and status stay visible on the Lock Screen. Whether recording or processing, Muon is always one glance away—on iPhone or Apple Watch.

■ What It's For
・Meeting minutes
・Lectures and seminar notes
・Interviews and reporting
・Daily voice notes

※ Transcription accuracy may decrease in noisy outdoor environments or for long-form lifelog-style recordings. Muon is optimized for clear speech in quiet environments.

■ Privacy
Audio is stored only on your device. During transcription and summarization, data is temporarily sent to cloud services; no audio is retained on the service side after processing.

■ Pricing
The first 3 days after install include full access to all features at no cost. After the trial, continued recording requires a subscription:
・Monthly plan: $6.99 / month
・Annual plan: $54.99 / year (34% off monthly)

After the trial, previously recorded data remains playable and viewable without a subscription. Only the creation of new recordings is locked.

Subscriptions auto-renew. Unless canceled at least 24 hours before the renewal date, the same plan renews automatically. Cancel anytime from iOS Settings → [Your Name] → Subscriptions.

■ Usage Limits
・Per recording: up to 90 minutes (auto-stop)
・Monthly total: up to 30 hours

■ Supported Languages
Japanese, English
