Sound familiar

Forgetting the words you learned
is not your fault.

01 Words you were sure you knew are gone a week later
02 You start over again and again, and stumble on the same words
03 You study in spare moments, but never see the progress
04 You cannot judge the balance between new words and review
05 You are never quite sure this pace will get you there in time

The cause

Which word, reviewed when.
The more words you add, the less you can track it.

By default You open the book on the train and work front to back
But The words you need today sit on a different page
And so The pile of words slipping away grows every day

That is why the work never turns into retention.

The fix

The app decides the route
to your test day.

Enter your test date. New words, words due for review, and how many of each — the app works it out.

With WordSprint Without review

Day learned 30 days later

~85% retained after 30 days

Measured internally from user study data. Without review, most words are typically forgotten within a month.

Served right before you forget

Retention is tracked word by word, and each one returns just as it starts to fade.

The new-to-review ratio is automatic

How far forward you go today, and how far back — the app sets both.

Open it on the train and do what is there

No study plan to draw up, no progress to manage.

Nothing left for you to decide.

6,000 high-frequency IELTS words

Selected from analysis of real IELTS papers, graded from band 5.0 through 7.5. Every word carries IPA and audio, so listening practice runs alongside.

How it works

Three steps to start.

1
Enter your test date

A one-time setup. Everything after that is planned backwards from it.
2
Do what is on the screen

New words and review are already queued for the day. Nothing to choose.
3
It comes back as you forget

Intervals stretch as retention grows, so the words last until test day.

Why this exists

Why this app
was built.

This app grew out of the developer's own experience studying for IELTS while preparing to move abroad.

Studying around a full-time job. Only spare moments to work with. Doing the vocabulary, and still not retaining it. It felt like a memory problem.

It was not. It was review timing. Which word to review, and when — managing that by hand is not realistic.

So the timing was handed over to a system. Band 6.5, achieved without leaving the job.

The hope is simple: that the same system gets you to your IELTS score without wearing you down.

Reviews

From people using it.

I used to forget words within a week and redo the same ones over and over. A month in, the words I learned early still come back to me.

T.K. Office worker, preparing to study abroad / 2 months

It fits in a 15-minute commute. I do not have to decide what to study, so I can start the moment I sit down.

M.S. Final-year undergraduate / 1 month

I had been looking for an IELTS-specific vocabulary app. It sticks to words that actually appear, so nothing is wasted.

R.H. Preparing for graduate school / 3 weeks

FAQ

Common questions.

Can I try it for free?

A 7-day free trial gives you every feature. Nothing is charged automatically when the trial ends, and a subset of features stays free after that.

What level do I need to start?

From a first attempt at IELTS through to score improvement. The vocabulary spans band 5.0 to 7.5, so you can start wherever you are.

How is this different from other vocabulary apps?

WordSprint counts back from your test date and decides your daily work — new words, review, and volume — automatically. It also tracks retention per word and schedules each review just before you would forget it.

How much should I study each day?

Ten to fifteen minutes is enough to keep moving. The test-date plan proposes the daily volume, so you only do what is shown.

Is it easy to cancel?

You can cancel any time from subscription settings in the App Store or Google Play. The one-time purchase needs no cancellation.

Vocabulary that stays,
without the deciding.
