I lay in bed, set the app to give me the answer after 5 seconds. Then I just lay there and listen to each interval, guess the name and then after five seconds the app gives me the answer and then moves to the next interval to guess automatically",

"rating": 5,
"title": "I am impressed",
"body": "I've tried quite a few different interval training apps (5-7 by my best estimate) over the past year or so and after ten minutes with this one I'm quite impressed. The sheer number of adjustable settings seems a bit overwhelming at first, but the in-app instructions are well-written and I was able to start testing myself almost immediately. That said, I would not recommend this app for someone who is not familiar with the guitar fretboard or interval construction. While I think ear training is a very important part of developing musicianship, I would argue that those who are just starting to study intervals would be better suited by app that demonstrates intervals on a piano/keyboard as they are much easier to \"visualize\" in the more linear fashion that a keyboard provides. It's obviously possible to play linear scales on one string on the guitar, but this is not how scales are most commonly used/constructed by guitarists. If, however, you do understand the fretboard layout and perhaps know some scale patterns already, this app will be useful to you. As a guitar player I'm particularly excited to try the alternate tuning settings, which will no doubt be challenging at first. Anyway, if you're on the fence, spend the $3 on this app - I believe it will be a powerful asset to anyone who uses it diligently, myself included.",

"title": "GREAT LEARNING APP",
"body": "I've been playing guitar most of my life and just recently began taking lessons. My instructor is focusing on intervals and hearing notes before they are played. I found this app to help me along and I will say it has advanced my interval/ear training by leaps and bounds. My guitar playing has jumped to a different level since I started the interval/sound training. It would have taken so much longer without this app. It is a very simple app that will take your musical abilities to levels you never knew where there. Anyone wanting to go to the next step should use this app. I could see this app helping with any instrument you play.",
