Doesn’t work – Music Looper - for Musicians Review

I tried using this app connecting my phone to my amp through an usb/lightning cable. While counting in, the metronome plays on my amp speaker, as expected. However, once the recording starts, it only comes through the phone speaker, which you won’t hear, even at low volume. Metronome also plays random and unpredictable ticks. UI also behaves inconsistent: turning on specific actions, e.g. metronome light sometimes works, other times doesn’t. This app doesn’t seem to record digital input, relies only on the microphone instead. The app is great as a concept but practically useless otherwise. I payed for the full version.
