Remembering things just became much easier. Based on Forgetting Curve, using the SM2 algorithm to repeatedly remind you to review. The goal is to help you remember anything you don't want to forget, such as learning a language or preparing for medical and legal exams, and even your whimsy that you don't want to be obscured by time. You can set questions for card front, then recall the answer according to the question. Your data will be backed up automatically to your iCloud account. That means all your stuff — flashcards, tags, preferences, and more — is safe, up to date, and available on all your devices. You can share notes with other users and invite them to contribute to your notes.
