Thanks @gardenbsquared!

I use the built in 'selfie' camera on the iPhone 6 plugged in yo A focusrite itrack pocket (it's a phone stand with a stereo mic built in) & I record into the Acapella app - you can use eq, compression & reverb in the app and it helps to neaten it all up

Those itrack pocket devices are going for £20 in the U.K. - worth it now that people have noticed!
