Description
Built to protect you — a recording tool designed for moments that matter.
The moment you open the app, recording starts. No buttons, no setup. Just open and record. Designed to waste not even a second in urgent situations.
[ Key Features ]
■ Instant Recording on Launch Recording starts automatically the moment you open the app. No interaction needed — respond to urgent situations immediately.
■ Pause and Resume Record only the moments that matter. Pause and resume at any time during recording. Full control from Dynamic Island, Live Activity, and the home widget.
■ Auto-Send via Email When recording ends, the file is automatically sent to your configured email address. Presets for Gmail, Naver, Daum/Kakao, Yahoo, Yahoo! Japan, and iCloud. Full SMTP standard support (SSL/TLS and STARTTLS).
■ SHA-256 Hash Integrity Every recording is sent with its SHA-256 hash. Cryptographically prove that your file has not been tampered with — crucial for evidentiary reliability.
■ Lock Screen Control Center Widget Add the recording widget to Control Center and start recording directly from the lock screen. One tap, no app-hunting.
■ Live Activity Timer Recording time is shown in real time on the lock screen and Dynamic Island. Check your recording status without returning to the app.
[ Privacy & Security ]
■ Direct SMTP, No Middleman Recordings are sent directly to your own email server. No third-party server in the middle, so your recordings are never exposed externally.
■ On-Device Processing All recording and processing happens on your device. Recordings are never uploaded to any external cloud.
