Introducing the new Fretuoso!

17 Dec 2015
If you have been using our Trainer HD educational games, the app has been rebranded!

Trainer HD is now Fretuoso. We also have a new logo!

We also have a new version out for you (5.8), which brings some major improvements to the old Trainer HD app. Just in time for Christmas!

  • Adds full support for new devices, including the new iPhone 6S and the large iPad Pro.
  • Also supports the latest iOS 9 system. We had to drop support for iOS 6, and you'll now need at least iOS 7.1 to use Fretuoso on your device.
  • 3D Touch shortcuts on the new iPhone 6S and 6S Plus. Force-press the app icon and you'll be able to quickly start or resume training, game, or free play.

  • See more of the instruments on the large screen of the iPad Pro.
  • We also fixed a bunch of nasty bugs!
All previous users of Trainer HD will be upgraded for free to Fretuoso on supported devices. Besides the free version, we will also still release and update the separate instrument editions, as well as the Complete Edition.

As we approach 2016, we have some very exciting features in development for the next major version of the app, Fretuoso 6.0. 

To keep up with updates on Fretuoso, feel free to follow the new @Fretuoso social accounts on Twitter and Instagram. We also still have an official Facebook page.

Texts From apps 6.0, now for Apple Watch

06 Jul 2015
We are proud to announce that the newest version of our Texts From apps (including the popular Texts From Jesus, Texts From Oscar Wilde and Texts From Founding Fathers) is out.

All of those apps now include built-in support for Apple Watch. This simple app allows you to quickly access the quote of the day from your wrist, as well as share it with your friends over Facebook. A Glance is even available for quick access to the daily quote simply by swiping up from the watch face.

In addition, Texts From Jesus now includes a lot of new verses (by popular request), mostly drawn from the Gospel of Thomas.

Texts From Founding Fathers also includes quotes from four new Fathers: James Madison, Alexander Hamilton, John Adams and John Jay.

Finally, we have redesigned the websites for each of these apps. Check them out!

Build cool iOS music apps with AudioKit

28 Apr 2015
If like us you are passionate about building audio-oriented apps for iOS, you might be interested in checking out the latest version of the new AudioKit open-source library.

Version 2.1 was just released, and it is the first version to include significant contributions from Catloaf Software's own lead engineer, Stéphane Peter.

AudioKit is a powerful audio library based on the popular Csound library, providing an easy-to-use API in Objective-C and Swift with powerful features for audio synthesis, processing and analysis.

Development is very active and new features are being added all the time, and we are proud of being a part of the core team behind this effort.

We plan to use AudioKit as the audio engine behind the next major version of our popular Trainer HD apps, and more. We're sure our users will be equally excited about the new features we'll be able to add to our apps thanks to AudioKit!

Announcing Trainer HD v5.7 with new Scales!

02 Apr 2015
We are proud to announce the release of the latest version of our Trainer HD series of educational apps for iOS. Version 5.7 is a major update to the apps, and besides a slew of bug fixes it contains a few nice new features!

  • The staff display has been greatly improved to make it more readable and intuitive. It now scrolls from right to left, which should feel more natural. It also now supports the common 8va/8vb notation to make it easier to read notes on the far sides of the fretboard. You won't have to count lines on the staff anymore!

  • Introducing scale focus! You will now find over 40 types of scales in the training options, allowing to focus your training on any one of them in the key of your choice. When picking a scale, only notes from that scale will be used for training.

  • Free Play mode can now apply training options to restrict which notes are shown on the fretboard, making it easy to visualize the scale of your choice on the fretboard map.
You can now apply training options to the fretboard map in Free Play.
  • A new wheel icon is now present in training, staff and free play modes, allowing quick access to the training options screen to change the settings without interrupting your session.

Remember, the training options do not apply to Game mode but only to Training and Staff modes. The new setting now also allows the fretboard map to be customized in Free Play.

The app is available right now as a free update on the App Store for most editions, although the update for the Banjo edition is slightly delayed but should be available very soon.

We have some major new changes coming up for version 6.0! We may even have an entirely new app coming out soon. Stay tuned... 

Trainer HD 5.6, now supporting the iPhone 6 and 6 Plus

08 Dec 2014
Just in time for the holidays, we are proud to announce the release of the latest version of our Trainer HD series of educational apps for musicians.

Version 5.6 brings full support for the latest Apple devices, the bigger iPhone 6 and 6 Plus. Of course, we still support all previous devices, as well as the iPad.

This is also the first release to bring full support for the new iOS 8, on all devices. As a side note, we have had to drop support for iOS 5 in this release, and a minimum version of iOS 6 is required to install this update. If you still have an old device running iOS 5 (mostly the first generation iPad), we urge you to update it to a newer version of the system if you can, or ask Santa to bring you a new iPad.

We have also fixed a whole lot of bugs, and managed to make the application significantly lighter, making it faster to download.

All editions of Trainer HD have been updated and are now immediately available to install from the App Store.

Happy Holidays!

Trainer HD v5.4 Now Available

18 May 2014
The latest version of the Trainer HD series of apps is now available on the App Store.

This new version includes the usual cohorts of bug fixes and improvements, but also contains one major new feature: daily practice reminder notifications.

Basically, after you've been practicing with the app on any of the instruments, you will be sent a notification 24 hours after getting out of the app reminding you that you should keep practicing. These notifications don't get sent if you have not logged any practice on an instrument, or if you have already mastered it (i.e. reached 90% mastery of the fretboard).

Additionally, if you don't want to get these daily notifications, they can easily be turned off by going to the settings menu and switching off the "Daily Reminders" button.

Practicing daily is the best way to improve your mastery of the fretboard in the long term, so we hope that you find these daily reminders useful!
