Oto Diary

About this app

■ 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 --- How It Works --- 1.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
