FASTEST WAY TO TRULLY SPEAK A NEW LANGUAGE- 3 Reasons Why Fluenz is Worth it: 1. Made for English Speakers The only language learning program anywhere specifically designed for English-speakers. Learn to speak Spanish, French, Italian, Mandarin, German or Portuguese anytime, anywhere. Each lesson has a video explanation of what you will learn, showing your the ins and out of the language you are learning. Then go straight to reading, writing and listening with workouts designed to for the information to stick. Learning a new language is not automatic but with the right tools and with explanations you can get there. 2. Total Approach Videos on streaming platforms and game like language apps are all useful but not enough to reach fluency. To learn a new language you need a fully integrated platform that a) explains the workings of your new language every step of the way in English, b) provides the tips and tricks English-speakers need to speak and understand that new language, and c) connects those explanations directly to extensive workouts and flashcards that take you to fluency. 3. Proven Results Unique among digital programs, Fluenz puts its program to the test every single month with some of the world’s most demanding learners at its face-to-face Immersion program in Mexico City. After ten years, hundreds of thousands of users and several complete upgrades, Fluenz continues to lead in positive reviews, critical acclaim, and the praise of those who are truly serious about learning Spanish. THE APP: Learn on the go with instant syncing, downloadable lessons, podcasts, and flashcards, all within the app. And because sometimes we need a bigger screen, gain automatic access to our full online, or downloadable desktop version as well.

Verdict

The call

The clearest difference is ads: Fluenz at none against Classix's shown. Fluenz also leads on iOS requirement (13.0 vs 15.1). Classix's advantage is update cadence (weekly vs every 3 months). On price, in-app purchases and device support there is nothing between them.
