IELTS Mastery Hub on Threads — free, open-source IELTS practice
1/
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 👇

IELTS Mastery Hub — a desktop app for Windows, Linux & macOS. Free, MIT licensed, no account, no ads.
📖 Reading — timed, split-screen, auto-scored 🎧 Listening — audio sections, progressive difficulty ✍️ Writing — AI feedback on the official scoring criteria 📊 Dashboard — see if you're actually improving

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.
4/
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 🦀

Heads up: independent, non-commercial educational project. Not affiliated with or endorsed by the British Council, IDP or Cambridge — IELTS is a trademark of its owners. Practice content is AI-generated for study purposes and may not be 100% accurate.

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.
