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

Verdict

The call

The clearest difference is price: TrueFire Guitar Lessons at Free against Interval Ear Trainer's $1.99. TrueFire Guitar Lessons also leads on rating (4.7 vs 3.9) and update cadence (every 2 months vs every 13 months). Interval Ear Trainer's advantage is in-app purchases (none vs 23) and review sentiment (67% vs 58%). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

TrueFire Guitar Lessons holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: TrueFire Guitar Lessons has 15K ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 67% of Interval Ear Trainer's written reviews are positive against 58% of TrueFire Guitar Lessons's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interval Ear Trainer ships an update every 13 months, TrueFire Guitar Lessons every 2 months. The most recent releases landed on October 17, 2026 and October 21, 2026 respectively.
