WordUp learns
how you remember
Instead of showing you the same words on a fixed schedule, WordUp watches how well you recall each one — and times the next review to hit right before you'd forget it.
The interval ladder
Day 0First time seeing it
Day 4First correct recall
Day 10Getting familiar
Day 24Feeling strong
Day 60⭐ Mastered
The gap doubles each time you nail it.
That's what makes it stick long-term.
After every card,
you rate yourself
Three buttons. Your honest answer sets when this word comes back.
😬
Again — back in 10 min
Blanked on it. WordUp resets the interval and brings it back this session. Mastery drops.
🤔
Hard — tomorrow
Almost had it. Short interval, no mastery advance. You'll see it again soon.
😎
Easy — interval doubles
Nailed it. The gap to next review roughly doubles. One mastery pip fills.
5 correct recalls
= Mastered
Each word has 5 mastery pips. One fills every time you rate it Easy — but they must be spaced out. Cramming doesn't count.
Word mastery — EPHEMERAL
Rate "Again" and the pip empties back. Mastery is earned through real spaced recall — not just tapping through cards fast.
🚀
You're ready.
Be honest with your ratings — the system only works if you are. A word you fake-Easy today will trip you up on test day.

EPHEMERAL adjective
lasting for only a very short time
🔑 A butterfly lives just weeks — its beauty is ephemeral. "e-FEM-eral" sounds like a trend from a past era — gone before it started.
"Her ephemeral fame faded by August — one viral video, then silence."
