About this app

Most English apps correct you. FizzUp upgrades you.

FizzUp gives you a native-speaker coach who holds real spoken conversations with you — then quietly rewrites what you said into how a native speaker would actually say it. You practise that upgraded version until it sticks. No red pen. No shame. No awkward silence.

HOW IT WORKS

You speak. Your coach listens, reacts, and keeps the conversation going — just like a real person. After each exchange, FizzUp shows you one "language upgrade": your exact words, and a natural alternative that a native speaker would use. You drill that phrase until it becomes yours.

YOUR FOUR COACHES

• Malcolm — warm, quick-witted. Great for everyday fluency and general confidence.
• Theo — high-energy. Built for job interviews, pitches, and high-stakes moments.
• Sophie — gentle and patient. Perfect if you feel nervous or embarrassed speaking.
• Emma — boardroom-level polish. For executives and business professionals.

Each coach has their own personality, voice, and teaching style. They remember you across sessions — your goals, your phrases, your progress.

WHAT MAKES IT DIFFERENT

→ Real conversations, not drills. You talk about your actual week, your job, your plans — not textbook scenarios.
→ Upgrades, not corrections. Your coach never stops you mid-sentence. Instead, after you speak, they show you the natural alternative — quietly, warmly.
→ Memory that builds. Your coach remembers what you struggled with last time and what phrases you've already nailed.
→ Prepared for your context. Tell your coach you have a job interview tomorrow and they'll come ready with the right vocabulary and scenarios.
→ Voice-first. This is a speaking app. Speak, don't type.

WHO IT'S FOR

FizzUp is built for people who understand English but freeze when they have to speak it. People who studied for years but still hesitate in meetings, on calls, or abroad. If that's you — FizzUp is the practice partner you've been missing.
