Some moments can't be captured in a photo or a sentence. Oto Diary is an audio journal that keeps the sound of your day in as little as 10 seconds. Just press and hold the cassette reel. One year later, on the same day, that sound comes back to you as a Time Capsule. The more days you record, the more your calendar and Year view fill up with a year that's uniquely yours. ■ Features · Press and hold the reel to record (choose 10, 30 or 60 seconds and more, once a day) · Label each tape with a title and one of five moods: Calm, Happy, Tired, Tender, Wonder · Calendar: every recorded day gets a waveform.
