Flashlet
Your flashcards on your Lock Screen.
Paste the list you already have. One card waits each time you pick up your phone. Be ready by test day.
How it works
Paste your list or type your cards, and set your test date.
Your reviews fit the days you have left.
A card waits on your Lock Screen. Answer it in your head, then tap to check.
You practice each time you pick up your phone. There is no app to open.
Flashlet brings back the ones you miss, so every card is due before test day.
Your time goes to the cards you don’t know yet.
Why it works
Flashlet is built on two study methods with strong evidence.

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.
Dunlosky and others, 2013
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.
Cepeda and others, 2008
Know how ready you are.
Set your test date. Flashlet predicts how many cards you will remember on the day, and plans your reviews to raise that number.
