Who is this for ?

Guitar Trainer is a tool for apprentice musicians with a desire to deepen their knowledge of their instrument. You just need to know the basics of your instrument.

More experienced musicians can also use this tool to learn the broad variety of alternate tunings supported, or simply to help them tune their instruments by ear with the builtin tuning notes generator.

What do I need to play?

As of May 2011, Fretuoso (formerly Trainer HD) is now available for iPhone, iPod touch and iPad and can be obtained straight from the Apple App Store. A free version, Fretuoso, is also available for you to try all the instruments before making your purchase.

As for the original Guitar Trainer, you will need a mobile device that supports Java applications and conforms to the CLDC 1.1 and MIDP 2.0 standards. Most phones produced in the last few years should be able to handle the application. If you can already play games on your cell phone, chances are that you are all set!

You will also need about 120KB of available storage for the application and its data.

Can I try it out for free?

Absolutely, as a matter of fact as of 2016 we no longer charge for the full version of the software! Go to the download page and get your own full copy right now. We hope you enjoy.

Does it work on my phone ?

The application is very versatile and supports a wide variety of mobile devices, from the smallest black-and-white handset to full-blown smartphones (including the iPhone with Fretuoso!).

A previous beta campaign was completed on many different devices. Click here for a breakdown of the devices that were tested. Phones from the following manufacturers were used succesfully (this list is in no way exhaustive!) :

  • Motorola
  • Nokia
  • Samsung
  • LG
  • HTC
  • Sanyo
  • Sony Ericsson
  • RIM BlackBerry

If your phone is running Windows Mobile, please check this FAQ for help getting proper Java support on your device.

Likewise, Palm users may check this FAQ for help setting up Java on their device.

The easiest way to find out if it works for you is still to try to install the free demo!

Is there an iPhone / iPad version ?

Fretuoso - Guitar Edition, a native version of the app for iPhone, iPod Touch and iPad is now available in the App Store! Full iPad support (as a universal binary) is also included. Please note that unlike the old Guitar Trainer, Fretuoso is not a free app.

However Fretuoso is also available as a free download, allowing you to try out all the instruments before you buy.
