See It in Action
From creating a deck to tracking your progress — here's how Flips works.
Create a deck in seconds
Name your deck, pick the front and back languages, and you're ready to add cards. Turn on read-aloud to hear each word spoken as you study.
See which words are fading
Every card shows its memory strength at a glance. Falling percentages tell you exactly which words need attention before they slip away.
Tap to flip, recall the answer
The front of the card asks the question. Recall the answer in your head, then tap to flip — simple, focused studying with zero clutter.
Check the answer and grade yourself
Flip the card to reveal the answer, then mark whether you knew it. Your honest self-grading drives the review schedule for every card.
Track your progress every day
The home screen shows today's cards to study and each deck's progress — from unlearned to mastered — so you can watch your memory grow.
