Audio recording app for iphones

[firemt66]

Hello fellow tapeheads,
          a friend of mine needs to find an app that will continue to record even when his phone gets locked from not using it besides recording. He is using  the voice recorded that the iPhone came with. what's the best app for this? Thanks in advance for any assistance:) scott

I am using the Rode Reporter App on my iPhone 7 (internal mic) and it works well. The phone does not go to sleep while the recording is active.
