This isn’t a bad app for the TX series of recorders but one of the major limitations is that you can’t transfer any of the recordings to your phone for review (let alone real-time monitoring). The only real-time feature that is useful are the real-time recording levels - but again without any actual audio monitoring, you can only *see* the levels, you can’t hear any of the remote audio.
