About this app

Your life, recorded. Nothing lost.

You can schedule to automatically start recording everyday at 9 am to 5pm. Or only on Weekdays from 10 am to 9 pm. Or Only on Weekends. It supports scheduled voice recording.

BlackBox Voice Recorder is always running so you never have to think about it.

Ratings and reviews

This app is honestly very useful and different from regular voice recorders. I like how it runs in the background and records everything automatically without me having to think about it. The fact that everything stays on the device also makes it feel more private and secure. Simple, smart, and really helpful for daily use.

Excellent and simple to use, runs in the background and automatically groups recording by days which is useful to me. Data is also being stored only locally and no unnecessary registration is required, as an app like this should be.

Very useful app for recording thoughts and ideas I have and then being able to replay them later easily. recommend if you have trouble remembering things and don't want to write everything down.
