Soundiary
Voice Journal
$0.99
New in 1.1: Save audio. Keep only the moments you choose — text-only by default. Five levels of voice sensitivity, and sensing that keeps going in the background.
Your day deserves to be remembered properly.
Soundiary turns a day of sound, heartbeat and body signals into a journal entry written in the quiet of the evening — nothing invented, nothing sentimental.
What matters more: unless you ask for it, your voice is never stored.
By default, Apple Watch samples the sounds around you, turns them into text, speaker labels and emotional features right on the device, then discards the raw audio. No recording files. No playback. Only meaning is kept.
Want to keep some of it? Turn on Save audio and each captured segment is also saved to your iPhone — ready to play, export or delete. The switch ships off, and it stays in your hands.
Through the day it listens quietly: sampled sensing, with silence and noise skipped automatically. It hears you from across the room, too — five levels of voice sensitivity, tuned to wherever you are.
Worried about battery? Power-saving mode samples just 6 seconds every 10 minutes, while body signals keep coming every 5. A whole night won't disturb your sleep.
In the morning, a story that's yours: what you did, who you met, how you felt, and what's still unfinished.
Who was speaking is your call: voices are grouped automatically, and you confirm or correct.
Everything stays on your device: no account, no cloud sync, no third-party SDK. Not even crash logs.
Paid download, complete on arrival: no in-app purchases, no subscriptions, no auto-renewal.
Requires iOS 18+ and Apple Watch Series 4 or later.
