Stop saying "very good" and "very tired". Upword puts one better word on your home screen every 3 hours and checks it in 10 seconds, right in the widget.
You know the words. You just sound flat.
"Very good", "very tired", "a lot of" — the same safe words, every sentence. Upword swaps them for the words fluent speakers actually use, one at a time, without opening an app.
DON'T SAY THIS. SAY THIS.
Every card is one upgrade: don't say "very tired", say "exhausted". Each pair comes with a short rule and a real example, so you know why the better word works, not just that it exists. And sometimes the simple word is right: Upword tells you when not to swap.
A NEW WORD EVERY 3 HOURS
Add the widget to your home or lock screen and a fresh word appears at 00, 03, 06, 09 and so on, all day. You learn while you glance at your phone.
CHECK IT IN 10 SECONDS, RIGHT IN THE WIDGET
Tap Check: a sentence with a gap and three options. One of them is always a trap — a look-alike word ("exhaustive"), the wrong form or the wrong context. Pick, see why, done. No app to open, no timer.
BUILT ON HOW MEMORY WORKS
Upword schedules every word with FSRS, the spaced repetition algorithm behind modern Anki, built on Ebbinghaus's forgetting curve. Each word comes back right before you'd forget it: in 3 days, then about 11, 35, 100. Easy words stretch out, hard ones return sooner. Miss one and it's back in a day or two.
YOUR CONTEXT
Choose Chat, Work or Exam. Chat skips stiff formal words; Exam puts work and exam vocabulary (IELTS, TOEFL, Cambridge) first.
WATCH YOUR PROGRESS
My Words shows every word as Learning, Learned or Mastered, with its next review date. Keep a daily streak — one missed day a week is forgiven. A gentle reminder at 19:00, only on days you haven't checked a word yet.
