Koedori ("voice-catcher") records your spoken day and keeps it on this iPhone. Follow it in text, or listen through the whole day in one continuous player. ■ Just leave it on No writing, no typing. Your spoken day becomes text in real time on your device, with auto-recovery from calls and interruptions. You just live your day. ■ Listen through the whole day The day player lets you play a full day's recordings from morning to night. Jump straight to the moment you want from a divider or transcript. ■ Calendar and places, quietly overlaid Read-only calendar events and opt-in places appear alongside your day's record. A day map lets you look back at the places you visited. ■ Everything stays on this iPhone Recording, real-time transcription, titles, and summaries are all processed on-device. Your audio and transcripts never leave your iPhone. Location records are also stored only on this iPhone. No account required. ■ Even while recording, quiet While recording, a single calm status lives on your Lock Screen and in the Dynamic Island. No nagging notifications. Your music and other apps keep playing. ■ Features - Long continuous recording (background capable, auto-recovery from interruptions) - On-device real-time transcription (with catch-up, on supported devices) - A day player for listening through a full day's recordings - Read-only calendar events and opt-in places overlaid on the record - A day map for revisiting the day's places - On-device AI titles and summaries (on supported devices) - Divider markers and Lock Screen controls - Timeline and search — find your words and jump straight to the moment they were said - Delete all recordings, transcripts, and recaps anytime ■ Honest by design Koedori only shows what it can truly do. When it is recording, it says so. When a recording was interrupted, the gap stays visible. About supported devices: transcription requires iPhone 12 or later (not available on iPhone 11 or iPhone SE 2nd generation). AI titles and summaries require an Apple Intelligence-capable device. On every other device, recording, playback, the timeline, and the day player still work. When recording conversations with people around you, please obtain their consent where appropriate.
