Natasha's Fluency Fix

Your English is good. It should feel natural. You know what you want to say. In your own language, you would explain it clearly, hold the room, tell the story, respond to the unexpected question. But in English, something changes. The conversation moves quickly. You start translating, constructing the sentence instead of saying it. You simplify an idea you could explain perfectly in your own language. Or the moment passes before you've said what you actually meant. Natasha's Fluency Fix is built for that gap. FLUENCY THAT FEELS NATURAL — NOT TRANSLATED Fluency Fix is for people who already speak English but want to use it more naturally under real conditions. Not grammar labels or disconnected exercises — language built around what you are trying to say, in the situations where you need to say it. What happened? What changed? What matters now? What does the other person need to understand? You build the language around the communication. So English becomes something you reach for naturally, not something you have to construct. START WITH YOUR FLUENCY PROFILE Your programme begins with an AI-guided spoken assessment. You speak — the conversation adapts and explores how you currently communicate and what you want your English to do. Your personalised Fluency Profile shows your strengths, your development priorities, and the communication goals that matter most to you. YOUR PROGRAMME IS MATCHED TO YOU Based on your profile, you follow one of three tracks: Business Professional Fluency — for professionals who work in English but want more ease, precision and confidence in meetings, presentations and business conversations. Confident Everyday English — for people whose English works but doesn't feel natural in travel, social situations and spontaneous conversation. Executive Leadership English — for senior professionals whose English is competent but whose spoken authority doesn't yet fully reflect their expertise or role. LANGUAGE IN CONTEXT Each session brings together audio and video coaching, speaking practice, structured activities, flashcards, and Companion Readers — stories that place the language you're developing inside real professional and everyday situations. You encounter the same language across different formats and contexts. It becomes something you recognise, then understand, then reach for without thinking. BUILT AROUND REAL COMMUNICATION Fluency Fix grew from live coaching with international professionals and one consistent observation: knowing more English is rarely the answer. The next step is usually doing more with the English you already have. Explain a complicated idea without losing yourself halfway through. Respond when you haven't rehearsed the answer. Contribute while the conversation is still happening. Sound as capable in English as you actually are. WANT PERSONALISED SUPPORT? When you want direct feedback or help with a specific communication challenge, you can book a live 1:1 session with Natasha from the app. This isn't about perfect English. It's about having access to your thinking and your voice — when you're speaking it. Your English is already good. Now make it feel natural.

Verdict
The clearest difference is ads: Natasha's Fluency Fix at none against Peak's shown. Natasha's Fluency Fix also leads on update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
