Learn Tools 101 is a Mac program that gives you access to basic concepts in Illustrator, Photoshop, PowerPoint, Word, and many other apps. This application provides you with a lot of study materials, brings you various flashcards for practicing, and lets you take quizzes to put your knowledge to the test.
From the main menu window of the utility you can select the subject you wish to study. Afterwards, the application provides you with a list of available activities. For example, the Photoshop chapter includes study material and flashcards while the Digital Photography section contains lessons, flashcards, and quizzes.
Unfortunately, not all lessons are available for free. You need to make in-app purchases in order to unlock all study materials for each of the listed tools.
Personally, I wouldn't install this application on my Mac for learning to work with tools like Photoshop, Illustrator, Fireworks, Word, PowerPoint, Excel, etc. Nowadays, developers provide you with integrated help guides. Plus, you can find all the information you could possibly require with a simple Google search, hence, without paying extra money.
In conclusion, I think you can find better and cheaper solutions for learning to handle apps like Photoshop, Illustrator, Fireworks, Word, PowerPoint, Excel, etc.
