Oto Diary

Not photos, not videos — a diary made of sound. Just 10–60 seconds a day. One year later, those sounds find their way back to you.

■ Description (max 4000 characters) Oto Diary is a new kind of journal — one made entirely of sound.

You've taken the photo, but somehow the feeling of that moment is gone. This app captures what photos can't: the air, the ambience, the life.

Record just 10–60 seconds of ambient sound, once a day. The morning coffee brewing. Your child laughing. Rain against the window. These are the sounds that make a life — and this app keeps them safe.

--- Cassette Tape UI ---

A nostalgic cassette tape design that feels tactile and alive. Hold the bottom reel to record. Release to save. Watch the tape wind as your memories accumulate.

--- Time Capsule ---

One year from today, the sound you recorded will be delivered back to you via notification. "I forgot my child's voice sounded like that." Memories fade. Sounds don't.

--- Calendar View ---

Every recording appears as a waveform on the calendar. Your streak of days becomes a visible record of presence.

--- Perfect for ---

• Parents who want to remember their children's voices
• Pet owners
• Anyone who struggles to keep a journal
• Travelers and adventurers
• Those who cherish everyday moments

1. Open the app
2. Hold the bottom reel (10–60 seconds)
