How it works

  1. Flashlet’s Paste a list screen: biology terms with their meanings, and 42 cards found.

    Paste your list.

    Paste the cards you already have. A Quizlet export works as it is.

  2. A calendar in Flashlet with November 12 picked as the test date, 33 days away.

    Set your test date.

    Flashlet fits every card’s reviews into the days you have left.

  3. A Lock Screen with a Flashlet widget that shows the card mitochondria.

    A card waits on your Lock Screen.

    Each time you pick up your phone, answer it in your head. No app to open.

  4. The same widget after a tap: the answer, make energy for the cell, with the buttons Again and Knew it.

    Tap to check.

    Again brings it back within 10 minutes. Knew it saves it for just before you would forget it.

  5. Flashlet’s Sets screen: Biology 101 on the Lock Screen, 72% ready for its test on Thursday, November 12, and three more sets, each with its own test date and readiness.

    Know how ready each set is.

    Each set has its own test date and readiness, and Flashlet brings back the cards that slip in each one.

Why it works

Flashlet is built on two study methods with strong evidence.

Sources
  1. Dunlosky and others, 2013: Improving students’ learning with effective learning techniques
  2. Cepeda and others, 2008: Spacing effects in learning

Each source was read on October 11, 2026.

  • Testing yourself beats rereading.

    A review of 10 study methods rated practice tests among the most useful, and rereading among the least. Flashlet shows the question first, so you recall the answer before you check it.

  • Spaced reviews beat cramming.

    In a study of more than 1,350 people, a longer gap before the review, up to a point, kept facts for longer. Flashlet spaces the reviews of each card across the days you have.
