The best thing about CallRecorder is that it doesn't need to be activated before a phone call. Once installed, the app will always record the conversations you have, except if you disable it from the application's settings. Thanks to this feature, you can, by default, record all your conversations.
All of them will be saved to your Android's memory, and you'll be able to listen to them directly from your device. You just have to choose one of the conversations from the list you have saved, and you'll be able to listen to it in just seconds.
CallRecorder is a useful tool that lets you save all your phone conversations. This way, you can have proof of receiving a phone call, whatever reason you might want it for.
Requires Android 2.3.3 or higher
