Call Recorder Automatic is an app to automatically record all the phone calls you have on your Android. No matter whether somebody calls you or you call another person, the recording gets stored on your device's memory.
In the Call Recorder Automatic setup options you can decide whether you'd rather not record incoming or outgoing calls. Plus you can create a whitelist of numbers that the calls won't be recorded for. And obviously from the options you can also erase any recordings.
Call Recorder Automatic is a very useful app that never hurts to have installed – who knows when you might need it? Do note, though, that although you can listen to calls recorded on your Android you can't export them via email, WhatsApp, or any other other medium without paying for a Premium license. You can buy one right from the app itself.
