Every musician should work on Ear Training (or Aural Training) and Interval Ear Training is a very important element of ear training. To put it very simply, you will learn to recognise the relationship between two notes (by distance), when they are played together or apart!
There are two types of interval listening, harmonic and melodic. In harmonic intervals the notes are played at the same time and in melodic the notes are played one after the other. Easy to remember: Melodic Intervals make melody, Harmonic Intervals make harmony!
Many of you will probably want to understand how the names are found and how to work out the interval note names in every key. For this info you probably want to check out my ebook Practical Music Theory (available from justinguitar.com) which will explain all the theory related to this.
This app deals specifically with Interval Ear Training, both melodic and harmonic. It will start very easy and gradually get harder as you get more correct and can pass each stage. You can choose from Piano or Guitar Input for your answers, and you can chose to hear the notes and guitar or piano. Personally, I'd recommend getting used to both. In "Training Mode" you can select specific intervals to work on if you are struggling with just specific intervals or types of interval.
I'm sure you'll find this app very helpful, all you need to add is practice time!
Best wishes, Justin

Tip for beginner ears
As i was finding this app difficult at first since it changes key with every question, i found if you take your guitar and find the interval on the fret board and compare it to the surrounding intervals to really hear the difference in pitches, this has been an amazing way to kill multiple birds with one stone, you familiarize yourself with the fretboard, understand scale construction and of course train your ear.
Easy to use and customizable
This has been a great app to learn intervals from. It has a training mode, which allows you to specify what intervals to train. I spend a lot of time using this feature for problem areas. I do wish this app had some additional / customization. I'd like to know at what pitch my ears start to waiver and it would be great to specify a pitch range in training mode.
Side note: I had a lot of issues being successful with this app until I started using mnemonics. Search for ear training mnemonics. There are a lot of good suggestions out there.
Use in conjunction with Justin's web site
To take full advantage of this, you should first watch the videos on JustinGuitar and then work with the app at the corresponding level. Without the videos, it would be very difficult and frustrating to train the ear. However, when you couple the videos reference to a song that starts with the root and the major third, it helps your mind remember that interval and then the app is a super resource to drilling it home.
With Family Sharing set up, up to six family members can use this app.
