Fresh Memory is an education application for studying languages with Spaced Repetition method and flash cards. Its primary purpose is to learn and repeat foreign words. But other areas can be studied as well, for example, country's capitals, flags, mathematical formulas, and even friends' birthdays. The study material is stored as collections of flash cards.

Fresh Memory has two studying modes: Word drill and Spaced repetition. The Word drill is the classic random browsing of flash cards. It can be used for getting familiar with the cards. The Spaced repetition is the main tool for repeating the cards. It automatically schedules repetition intervals of each card according to its difficulty. This method allows to quickly study any structured material and keep it in memory for a long time.

In Spaced repetition, the user first sees a card question. He thinks of the answer, and opens the correct answer. The user checks if his answer was correct and evaluates himself with grades from 0 to 5. The grades depend on how difficult it was to recall the card. The application then schedules the next repetition of the card depending on the grade. With each repetition, the next interval automatically increases, as the user knows the card better. The repetition intervals may range from several minutes to over a year, without a limit. The easier the card is for the user, the longer its interval becomes. If a card is difficult to remember, it is shown more often so that the user would have more chance to study it.

The flash cards are stored in dictionaries. The user himself can create the dictionaries and add cards to them. The application allows to open several dictionaries in tabs at the same time.

Multi-sided cards. Paper flash cards have two sides: question and answer. Computer cards can have multiple fields. These fields are needed to store auxiliary information: word pronunciation, example, etc.
