Flitsen

Flashcards that come back smartly, exactly when you need them. No endless cramming, just more remembered. Create your first set in a few seconds.

Test in a few weeks? Or just curious what ‘brainrot’ really means? The Flitsen app helps you remember things without spending hours on it.

How it works Your cards live in boxes: • Box 1: new or tricky. Comes back every day. • Box 3: starting to stick. Comes back every 3 days. • Box 5: you’ve got it. Comes back every 5 days.

Know it? The card moves up a box. Don’t know it? It comes back soon. What you know well, you see less. What’s still tricky stays on your path.

What you can do • Make sets with your own emoji and color. Your sets are allowed to look good. • Set a target date, so you know when you need to be ready. • Practice forwards or backwards: question first or answer first. • Turn on a reminder, so you don’t forget. • See at a glance how many cards are in each box.
