The best app for Justin’s ear training course, and a great standalone app (I imagine)

Practicing ear training on this app with the simple feature that told me whether I was right or wrong when guessing a note helped me hear the notes and the intervals clearly, despite differences in volume and timbre (when intervals were played in different places on the guitar neck) that initially had me confused. I’ve only used this app to practice three intervals at the time of this review - namely, the octave, perfect fifth, and perfect fourth. It helped me pass Justin’s ear training test by increasing my score from around 75% to 95%, and that score difference is indicative of how much my ear skills have improved.
You could record yourself playing different intervals and use those recordings to train your ears, but this app makes that process much easier and significantly more convenient; I can open it up, practice for just five minutes, and improve my skills instead of having to deal with the UI of a recording app and figuring out a system that tells me whether I’m right or wrong when guessing a note only after I guess and not before (for example, by the title of a recording indicating the interval being played).
All of that is to say that this app makes ear training much easier and is quite cheap for what it offers, along with the fact that the money spent on it would support Justin and all the free videos he puts out online for learning guitar. If you can, I highly recommend buying it.

So unintuitive

Aweful. I gladly pay for apps, but this was just a donation that turns me away from Justin Guitar.

Wasted time trying to figure it out, text information is bad. Video was worse!

Phenomenal app.

Interval training at will and on the go without the need for an instrument. The ability to customize your own training regimen allows you to focus on specific problem areas. The app is a bargain for the price, same as almost anything Justin offers on his website. If you are looking for a serious and easy to use ear training app this one is for you.

Terrible instructions. Don’t waste you money.

Absolutely no idea how to use this app. The instructions are absolutely useless. They send you off to one of Justin’s links on the internet with absolutely zero reference on how to use the app.

Read this if you need help!

When I initially opened the app I was confused on what to do. (I’m a slow minded individual lol) Here’s how to work the app-

Level 1:
Begin on the screen with the fretboard. Play the sound and decide if it’s a 4th or 5th interval. Choose your answer by either selecting the 4 or 5. If you picked correctly the button will turn green. If incorrect it will flash red. Eventually, once you answer enough correctly it will move you on to the next level. I highly recommend going over to Justin guitars website and learning ear training before attempting this.
It is a frustrating and rewarding experience to learn!
🙂
I’ve only gone up to the second level but I will update if anything changes on the app.

Have a wonderful day!
