If you want to record your phone calls, use Call Recorder - a free app for recording your voice or have recorded calls and would like to save them for later playback, this is the best app for you.

With Call Recorder, you can record calls from your Android phone. You can select either incoming or outgoing calls to record, or both. You can even add comments or notes to the recorded calls.

If you're wondering how it works, the concept is simple: the app records the incoming or outgoing call, the audio is saved in your device's phone memory or in the memory card, and then it saves it as an MP3 file. After recording, the file is saved in a folder inside your device or in the Android's SD card. You can later import those files into your device and listen to them.

If you're using the app for the first time, you'll need to download the setup file from Google Play. After installing it, you'll be able to record phone calls.
