## What is Guitar Interval Ear Trainer?

One of the first steps in ear training is recognizing intervals, which are the distances between two notes. Because every melody, chord, or scale consists of a series of intervals, this is a fundamental and valuable skill in music.

Our app is designed to help you identify intervals and learn how to locate them on the guitar. By improving your knowledge of intervals on the guitar, you can easily decipher chord progressions, replicate melodies as you hear them, gain a better understanding of written music, and more.

Key Features

- Choose from 17 selectable intervals, ranging from unison and minor seconds to major tenths.

- Select between melodic and harmonic intervals, for both ascending and descending.

- Get a visual representation of intervals on the guitar.

- Choose the root note from two octaves.

- Use portrait, portrait upside down, and landscape modes.

- Optional voice function for convenient training, even in the car.

- Practice and test (quiz)modes.

- Intervals are categorized by difficulty level, with each group having 6 progress indicators corresponding to different interval types (melodic ascending/descending, harmonic ascending/descending, random melodic, random harmonic/melodic).

- Optional reference melodies for each interval can be played, helping you learn intervals faster.

- When practicing harmonic intervals, the app classifies the interval as consonant or dissonant, helping you identify harmonic intervals effectively.

- Access over 10 alternate tunings, including NST (new standard tuning) and all fourths tuning, making it easier to recognize similar patterns across the fretboard for the same intervals.

- An option to play only tapped notes (interval type "None") is available, which is useful for figuring out melodies or experimenting with alternate tunings. 

- In practice mode, the root can also be played as the second note in the interval.

-In Test Mode, you can choose an infinite think-time. When infinite think-time is selected, tap anywhere outside the fretboard to replay the interval.

- The app supports left-handed and bass guitars.

- Enharmonic equivalent notes are used to maintain classical interval names, ensuring consistency with written music (e.g., the 3-semitone interval C - D# will be called a minor third C - Eb).

- Practice and test intervals within a scale context, as the same intervals can sound different in various scales. This feature allows you to play partial scale runs of the interval automatically backward and/or forward in your chosen scale.

- Visualize over 15 essential scales on the fretboard. The scale notes are clustered and colored to clearly indicate the root note to which the interval applies.

- Our app is universal, designed for iPhone and iPad.

- Support for all screen sizes.

- Dark mode support (iOS 13+).

- Tested on iOS and iPadOS 26.

### 5/5 — very helpful

*2025-06-28*

this has been very useful to me. i like that it has songs associated with the intervals to help with memorizing. thank you for making the app.

### 5/5 — Between interval time suggestion

*2025-03-06*

Hello, in test mode could you increase between interval time? It’s only 3 seconds right now, in my opinion a little too short, it doesn’t give me enough time to reflect. 

ps: Thank you so much for previous changes.

**Developer response:** Thank you for your review and for sharing your suggestions. We have just released an update allowing you to extend the between-interval time up to 15 seconds. Along with your idea for an unlimited time option in test mode and the ability to replay intervals, we hope this makes your experience even better.

### 5/5 — 1 suggestion

*2025-02-22*

In test mode I wish there was unlimited time option and the option to click so we can hear the intrrval over and over again.

**Developer response:** Thank you for your review and for sharing your suggestion. Your idea for an unlimited time option in test mode and the ability to replay intervals was really helpful, and I'm happy to let you know we've just released an update that includes these features. Thank you again for your support!

### 5/5 — Life saver for learning intervals

*2020-09-28*

It just keeps playing the intervals and then says the interval after a length of time you set. This allows you to just listen and name the interval without having to touch anything. 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

### 5/5 — Excellent - brilliant learning tool for intervals on a fretboard

*2019-01-10*

Just had App 10mins but already delighted with it! I've been practicing intervals with other methods over past few months.

This App has everything needed to learn quickly : reference tunes, tells you the classic interval name plus indicates the semi-tone difference between notes. Like a training guitar and teacher in your pocket.

Well worth the £1.99!

### 5/5 — Teacher

*2018-11-03, version 4.71*

Awesome‼️‼️‼️‼️‼️‼️‼️🙏🏾🙏🏾🙏🏾🙏🏾

### 5/5 — Absolutely superb!

*2018-02-17*

If you could only have one app you should have this one, if you are a musician.  I am fairly confident that it will help improve my musical abilities tenfold.  The design and execution is flawless and the detail is mind blowing for the cost.  Do not hesitate.

### 5/5 — Excellent ear/interval training

*2016-08-23*

I have tried many apps and most are garbage.  This app has a bit of a learning curve, but once you figure it out it is easy to use and makes learning intervals and notes easier to recognize.  I highly recommend this app!

### 5/5 — Great for guitarists

*2016-03-25*

Having never done any interval training (or even having known that was a thing) this app has been a good introduction, and as it is specifically for guitarists and the display is based on a fretboard, it is easy to transfer the learning to the instrument. All the options are a bit overwhelming at first but they all seem to be useful and it's nice to have it so easily configurable.

### 5/5 — Very good

*2015-12-24*

Interval distance line is very good.
