Great to use with the built-in microphone
This audio recording app works well with the built- in microphone, and has an option to record in lossless 32-bit WAV. Nice and simple. On the down side, it cannot record with an external microphone plugged into the 3.5mm jack of the iPhone 6+. Adding that feature would make it perfect for people who want high quality recordings directly added on their iPhone. Good app, recommended if you only need to use the built-in microphones.
