The 98% Problem: Why Most Learners Quit

Why they quit:
  • The app decides what you learn
  • You recognise words but can't use them
  • There's nothing to do when you're tired — you're always in learning mode
  • You can't see real progress, just how many games you've played
  • You still can't say what you mean after months
Why WordCat is different:
  • You choose what you learn
  • You prove you can use it
  • There's always something that's fun and matches how you feel
  • Your Diary shows real evidence of growth
  • 2,200 graded assessments that make learning feel like entertainment

That gap isn't just "more vocabulary." It's learning to use English creatively — to build sentences from your own thoughts, again and again, until it feels natural.

The App-Hopping Trap

You've tried to fix this, but most tools keep you passive:

📱
Duolingo — Fun, but you just tap buttons and repeat fixed phrases.
👨‍🏫
Video Courses — You buy them with good intentions, but quit because 'watching' isn't 'doing'. No feedback = no fluency.
🗂️
Anki — Powerful, but you collect thousands of cards you never see again.
📺
Netflix — Enjoyable, but too fast and too dense to learn from.
💰
Tutors — $30/hour is expensive to maintain long-term.

You don't need another app. You need a system that knows you can't be 100% productive every day. WordCat adapts to your energy, not the other way around.

Three Gears. One System.

Stop feeling guilty when you're tired. Switch gears instead. We combined active training with passive immersion so you never break the loop.

1
🔋

Low Energy

The Feed

Too tired to study? Just scroll. Watch short videos, tap simple spelling tests, and shadow real English. It feels like taking a break, but keeps your English alive.

Goal: Maintenance
2
🎧

Medium Energy

The Academy

Ready to listen? Songs, audio passages, and structured courses — all graded by level. Listen, read, answer comprehension questions, write a response. Scaffolded immersion in your own language whenever you need it.

Goal: Comprehension

🔥

High Energy

My 36 + Training

Ready to grow? This is the gym. Create new vocabulary from your own sentences, practise with personalised trainers, fix your mistakes with the Tutor, master your active words. It's hard work for 20 minutes — but this is how you break your plateau.

Goal: Band Shift

Your Vocabulary, Your Way

One conversation. Unlimited vocabulary.

Type a sentence, ask a question, enter a topic, or snap a photo. The Vocabulary Builder proposes 8–12 word candidates — you pick the 4 that matter most. Every card is built from a conversation about YOUR English.

Frequently Asked Questions

Is WordCat right for beginners? +
WordCat is designed for elementary to advanced learners (A2 to C1). If you're a true beginner with zero English, take the free CEFR placement test first — and consider starting with a more basic app until simple sentences feel comfortable.
How does the My 36 system work? +
You always have 9 sentence cards active. Each card has 4 keywords, so you're focused on 36 words at any time — plus 36 collocations the app generates automatically. When you add new cards, the oldest move into long-term Memory. Nothing is lost — graduated cards come back via spaced repetition.
What happens to my old vocabulary? +
Nothing is lost. When a card leaves your My 36, it moves into long-term Memory. The Memory module brings it back at the right time, testing whether you really know it. Get something wrong and it goes into your Drill Pack to come back until you nail it.
Can I practise speaking? +
Yes. Pronunciation Practice records you and gives word-by-word feedback. Every song and passage has speech-to-text practice. The Situation Trainer lets you speak through any real-life scenario. And the chat characters in Academy all support audio in and out.
How does the free trial work? +
You get 48 hours of full access — no credit card required. Explore everything, create as many cards as you like, and see if the system fits you.
Can I cancel anytime? +
Monthly plans can be cancelled anytime. Annual plans come with a 14-day money-back guarantee.
What devices does WordCat work on? +
WordCat is a web app that works on modern browsers — phone, tablet, and computer.
How is this different from Duolingo? +
Duolingo is great for starting. WordCat is for when you're ready to move past fixed exercises and start creating your own English — from your own sentences, photos, and topics.
Can I use WordCat for IELTS or TOEIC prep? +
Yes. When creating cards, you can choose Everyday, IELTS, or TOEIC focus — the vocabulary shifts to match. The Academy and Course catalogue include exam-focused content.
How much time do I need per day? +
Around 20–30 minutes of focused WordCat practice beats hours of passive watching. On busy days, the Feed gives you 5-minute micro-sessions.
How much content is included? +
2,200 graded assessments (1,200 songs and 1,500 audio passages) across CEFR levels A1 to C1, a 250-lesson free fluency course with more courses arriving, and unlimited vocabulary creation from your own sentences and photos.
Do I need a teacher? +
You can absolutely learn independently with WordCat. If you also work with a teacher, they can help you build content that feeds back into the system.
