Guitar Trainer 1.2 for Java ME and Blackberry

14 septembre 2011


The original Guitar Trainer app for Java ME and BlackBerry has just been updated to version 1.2.

The main changes in this release are a full Chinese localization (both traditional and simplified), as well as some other cosmetic changes to bring the app more in line with Guitar Trainer HD for iOS.

This app is still widely in use around the world and is available for purchase straight from our website at MobileTutor.org, or at a variety of App Stores, including the BlackBerry App World store.

You may also want to check out the free demo version if you haven't already.

We are continually expanding the international reach of our apps with new updates. More languages are coming soon to Guitar Trainer HD for iOS, please stay tuned !

Guitar Trainer HD v3.0 is now available

2 août 2011
We are proud to announce the release of version 3.0 of Guitar Trainer HD and Guitar Trainer HDx, the first universal version of these educational apps for iPhone, iPod touch and iPad.

While previous versions worked fine on iPad, they were not native to this tablet. Version 3.0 now brings it to scale with a full iPad interface tailored to the bigger screen.

This new version of Guitar Trainer HD also includes a number of bug fixes for the iPhone side of things, and sports a new look.

The app is a completely free update for existing users, and pricing is not changing either, so if you haven't yet had a chance to try Guitar Trainer HD out, now is the time!
