Good app, some issues – Recorder App: Voice Recorder Review

Awesome app, I've had this for years. Really easy to make quick recordings so I can keep track of melody ideas. I recently bought an iPad Air 2 and it doesn't work as well. For whatever reason, the recording is coming in very soft. There's no option to calibrate or switch up the recording level. I've tried other recording apps and they work fine.
