Hi 👋 I'm Rui, and I made Mempo, a small free app for learning upper-intermediate to advanced English words (B2, C1 and C2).

Why I built it
When I studied for English exams, I had long word lists and kept forgetting words a week later. Flashcard apps felt heavy: you need an account, there are ads, or you have to build your own decks. I wanted something I could open and use for 5 minutes a day, where the words are already there.

What it does

🃏 Swipe word cards: Know, Not sure or Don't know. Tap a card to flip it.
🔁 Spaced repetition: words you know come back after 1, 3, 7, 14, 30 and 60 days.
❌ A "Don't know" list keeps your hard words until you get them right on two different days.
🎯 A level test with 30 words shows you where to start.
🌏 6,128 words, each with Chinese and Spanish translations, example sentences and a British English recording.
🔥 A daily goal, a streak and stats.

What I care about

Free, no account, no ads. Your progress stays on your device.
Works offline and installs like an app on iPhone, Android or a computer.
You can move your progress to another device with a QR code.
The app itself is in English, Chinese or Spanish.

I'd love your feedback

Is the swipe direction natural to you?
Which language should I add next?
What would make you come back every day?
