gFlashcards

gFlashcards is an educational application that allows you to study by using flashcards. To use the program you will first need to create an account online.

This will only take you a couple of seconds. Then, you can login and start looking for pre-made flashcards or even create your own ones. There are flashcards on multiple subjects and you can search them by simply typing keywords. If you like a flashcard set, you can mark it as favorite, and it will appear on the main menu of the application, so you do not have to search for it again. Some cards may even contain sounds.
Sadly, to create your own cards, you will have to go the developer's website, login and do it from there, as you cannot do it directly from the application. Once you have created you own cards, they will appear in "My Sets" in the application. The program offers a simple and nice user interface that will not cause you any difficulty.
All in all, if you are looking for an application that helps you study and memorize content by using flashcards, gFlashcards may be an excellent choice.
