Memizr

Use scientific principles to retain everything you learn by spending just minutes a day

Flashcards are a great way to study. Unfortunately with traditional flashcards, you are stuck reviewing easy cards far too frequently and don't get to spend enough time on the hard cards to really remember them. Using a method tailored to each individual, Memizr schedules cards for review at just the right time.
