## What it is
BCR is a basic, automatic call recording app for rooted Android devices or devices running custom firmware, installed as a Magisk/KernelSU module. It records incoming and outgoing calls in the background with multiple output formats and minimal resource usage.

## Use cases
- automatically record phone calls on a rooted Android device
- record calls to an SD card or USB storage
- record calls in lossless FLAC or WAV format
- record calls with separate uplink and downlink stereo channels
- set auto-record rules for specific contacts
- record calls before first unlock after reboot

## When to choose
- your Android device is rooted with Magisk or KernelSU
- you want a simple, privacy-focused recorder with no network permission
- you need automatic background call recording with minimal battery impact
- you want flexible output formats including lossless options

## When to avoid
- your device is running stock, unrooted firmware
- your device does not support the VOICE_CALL audio source
- you need workarounds for OEM battery optimization or app killing
- you need support for Android versions older than 9
