Every IELTS prep app gives you two free tests and then asks for your credit card 💸

The test is already expensive. The practice shouldn't be.

So I built a free one and open-sourced it 👇

The writing part is the one I'm most proud of.

Writing is the hardest skill to self-study because you need someone to read what you wrote. Getting structured feedback on why a paragraph is weak beats writing essays into the void.

Built with Tauri — TypeScript + a Rust core. Mock exams run 3 hours, so it had to be a small, fast native app rather than a browser tab pretending to be one 🦀

If you're prepping for IELTS I'd genuinely love to know whether the formats feel close to the real thing.

And if you know someone studying right now — send it their way 🍀

Try it, break it, tell me what's wrong.

IELTS prep tools: 2 free tests, then a paywall 💸

So I built a free one. Open source, MIT.

📖 Reading (auto-scored) 🎧 Listening ✍️ Writing w/ AI feedback 📊 Progress dashboard

Built with Tauri: TypeScript frontend + Rust core.

Mock exams run 3 hrs — shipping a whole Chromium for that felt wrong. Small native binary instead.

Timers + scoring live in Rust, so no drift, no devtools cheating.

If you're prepping for IELTS, I'd love to know if the formats feel realistic.

If you're a dev, the Tauri/Rust side is open to poke at.

IELTS Mastery Hub

Free, open-source IELTS practice — reading, listening & AI-graded writing

👋 Hey Product Hunt!

I built IELTS Mastery Hub because IELTS preparation has a frustrating pattern: two free mock tests, then a paywall — and half the tools don't even match the real exam format. For a test that's already expensive to sit, that felt like the wrong place to put a subscription.

So this is the opposite of that. A native desktop app, completely free, open source under MIT, and running on Windows, Linux, and macOS. No account, no trial, no upsell.

Quick demo video:

What's inside:

📖 Reading — split-screen timed practice covering the official question types, auto-scored instantly

🎧 Listening — audio-driven sections with progressive difficulty

✍️ Writing — a dual-pane editor with AI evaluation across the official IELTS scoring criteria, so you get structured feedback instead of writing essays into the void

📊 Dashboard — track your scores and see whether you're actually improving over time

Under the hood: TypeScript frontend with a Rust core, built with Tauri — so it's a small, fast native binary rather than a browser tab pretending to be an app. Important when you're sitting a 3-hour mock exam.

I'd love to hear from anyone who's prepared for IELTS (or any English exam) — what did you wish existed while you were studying? And if you're a dev curious about Tauri, the codebase is open and contributions are very welcome.

I'll be around all day answering questions in the comments 🙌
