SoundRecorder for Android (com.thinkleft.soundrecorder) on Google Play
This is a ported version of Android's SoundRecorder. SoundRecorder is available on most Android devices but for some reason, it is not bundled on the Nexus 5 with Android 4.4 KitKat. If you need SoundRecorder on your Nexus 5 or any other device, install this app.
