Making your own flash cards is a tried and tested method of getting up to speed on a subject. Tinycards takes the concept to the next level, putting more than 10,000 decks on your iPhone or iPad, on subjects including science, maths, history, geography and foreign languages.
Unlike old-school cards, Tinycards is interactive. Some decks ask you to select from multiple-choice answers; others ask you to type in a response and many are illustrated. Foreign-language decks play recordings of a word pronounced by a native speaker.
The app also adapts to your learning, using a technique called spaced repetition. Because, over time, you tend to forget what you learnt, the app intelligently resurfaces cards you’ve mastered. It also notices which cards you’re struggling with and keeps reshuffling those until you ace them consistently.
In addition to offering thousands of premade decks, Tinycards also allows you to create your own and share it with others. (Esoteric Harry Potter trivia, anyone?)
So pick a topic and begin. No index cards or permanent markers required.
