The real problems of preparing for Cambridge alone vs What Lunvello does differently
The real problems of preparing for Cambridge alone
You don't know if you're ready: You study for weeks but have no objective way to measure your level against the exam.
Generic apps don't prepare exams: General vocabulary isn't the same as Key Word Transformation or a 250-word Essay.
Daily practice gets expensive: A 1-on-1 tutor runs €30-50/hour, and keeping that up for three months blows most budgets.
The exam costs €200 and it's non-refundable: Sitting it without clear data on your level is an expensive gamble.
What Lunvello does differently
Real visibility on your level: Your Exam Readiness Score combines practice volume, accuracy, and exercise variety to guide you on when to sit the exam.
Identical exam format: Every exercise replicates the structure, types, and difficulty of B2 First or C1 Advanced.
Feedback by Cambridge criteria: Your Writings are evaluated on Content, Communicative Achievement, Organisation and Language — the same 4 criteria real examiners use.
Unlimited practice from €13.33/month: A full quarter of premium preparation for less than 2 hours with a tutor.

Frequently asked questions
What you need to know before getting started.
Does this replace a language school?
It depends. If you haven't spoken English with anyone in years, a language school will give you what Lunvello can't: a real person in front of you. Lunvello gives you the rest of the exam — Reading, Use of English, Writing, Speaking, Listening, the real format. A lot of people combine both.
Why not just use ChatGPT?
You can. I've tried it. You ask it for an essay and it corrects you with pats on the back: "nice work, you could improve cohesion". OK, but is that a Band 3 or a Band 5? Lunvello tells you Band 3 with the four official criteria (CA · CO · O · L), runs the 1 h 20 min timer for Reading & Use of English, generates Listening with four different voices and one accent per Part, and in Speaking puts you inside the 4 Parts of the oral with simulated interlocutor and partner — not a text chat. Cambridge marks it this way. Lunvello does too.
Can I try it before paying?
Five days free with EVERYTHING — AI Speaking, Listening, Lex, mock exams — when you sign up. No credit card. When the five days end, you choose: subscribe (monthly or quarterly) or stay on the Free plan indefinitely. No fine print.
What if my level isn't at B2 yet?
The diagnostic places you at your real level from A2 upwards. If you're far from B2, I'll tell you straight and recommend what to do before paying for the subscription. I have zero interest in charging you for something that won't help you.
Who's behind this?
One person. Me, Roberto. No marketing team, no investors, no call center. Just the product. If something breaks or you have questions, you email support@lunvello.com and I answer you myself.
Do you have a mobile app?
No App Store or Google Play app, but Lunvello works as a PWA: you install it on your phone in 10 seconds and it behaves like a native app (home-screen icon, fullscreen, basic offline support). See the install steps here — guides for iPhone, Android and desktop.

Who's behind Lunvello
I'm Roberto, software engineer and founder of Lunvello. I built this platform because when I was preparing for my Cambridge exam, I realised there was no tool that combined the real exam format with specific criteria-based feedback. Lunvello is that product — built with obsessive attention to detail and improved every week.
