I use transcribe on my computer and I was pleasantly surprised that this app had the main features I like in that program. The ability to slow down and loop a small portion of the song helps me transcribe more accurately and is especially useful for getting tricky rhythms and complex melodic lines. It allows me to transcribe without having to bring the computer out which is especially useful for teaching purposes. I love being able to plug in my phone and slow down songs to get students to practice with as well as transcribing for them or with them. Being able to loop just one chorus of a solo or bass line (etc) is a useful tool since I dont have to rewind back to practice it multiple times. Its intuitive and easy to use. Would definitely recommend it to musicians who are looking to transcribe music or practice along with recordings.
