Interval ear training is an essential skill for progressing musicians... 

Time Trainer App

*more pix of the app screens are on the app store!

Learning to recognise musical intervals (distances between two notes) by ear is imho and essential skill for progressing musicians in every style and every instrument. Developing this skill will improve your whole musicality, help you to transcribe songs by ear and you understanding of the fingerboard.

In this app I give you two sound choices piano or guitar and two input options for your answers, a piano keyboard and a guitar fretboard. I think guitarists should be using both sounds and both interfaces, while most other instrumental players will stick to the piano input I suspect.

To make the most of the app you will most likely want to check out my free Aural Training Course which will explain the best way to learn this skill. The app follows the same sequence of learning as the course so will compliment it perfectly.

Hope you enjoy it, email me your suggestions for improvement and I'll try and get as many done as I can in future updates!

When is the android version coming out?
Well, it could be a while. Many android users asked me to make an android version of my Time Trainer app, so I did, and so far it's only made back a quarter of what it cost to make :( Android apps just don't sell well enough at this point to make it worth it and I can't afford to lose thousands of pounds on developing apps for less than a thousand people to buy. When the Time Trainer Android has earned it's money back I'll send this one off for android development. Very sorry, hope you understand!


Thank you!!

Big thank you all at Apreel for their hard work making this app so awesome!
