Blackbox: 24/7 Audio Recorder

Never miss an important moment again.
Blackbox records audio continuously in the background — just like a dashcam for your life. It silently keeps the last few hours of audio, automatically freeing up space, until you decide something is worth keeping.

WHAT IS BLACKBOX?
Blackbox is a privacy-first audio recorder that runs 24/7 in the background. It maintains a rolling buffer of your chosen duration — automatically deleting old audio to save storage. When something important happens, one tap locks it forever. That's it.

CORE FEATURES
Always-On Background Recording
Set it once, forget it. Blackbox records in a continuous loop while you go about your day. Old audio is auto-deleted. You stay in control of what gets kept.
Lock & Protect Important Recordings
One tap locks any recording and shields it from automatic deletion. Perfect for legal evidence, key conversations, or anything you never want to lose.
Flexible Retention Settings
Choose how far back Blackbox remembers — from 1 hour to 1 year. Your phone, your rules.
Optimized Audio Quality
16kHz to 48kHz recording quality. Source profiles optimized for meetings, voices, or outdoor environments. Automatic storage management keeps everything running smoothly.
100% Private & Offline

All recordings stay on your device
No cloud uploads, ever
