Lingua Fortis is built on two primary pillars designed to get you to fluency quickly and effectively: prioritize the most frequently used words and patterns in the target language, and build muscle memory through repeated exposure until you can use them instinctively. A relatively small number of words and patterns make up the vast majority of any language. To get to fluency as quickly as possible, you need to master these most common words first. In order to identify these high priority words and patterns, we analyzed millions of real sentences. The results are often counterintuitive. This is because research shows that many traditional language learning materials prioritize vocabulary that feels like it would be common but is in fact statistically rare. Data analysis enables us to genuinely prioritize the parts of the language that are used most, rather than what intuitively feels like it would be. Then we drill these patterns. Fluency in a language is different from knowledge about a language. It's developing muscle memory. Rather than explaining a pattern to you, such as a grammar rule, and expecting you to then apply it in real life, we train it through large amounts of repetition until your brain internalizes the pattern and you can produce it instinctively. Our spaced repetition algorithm ensures that this training commits what you are learning to long term memory. Every feature adapts to your level, making Lingua Fortis equally effective whether you're starting from zero or breaking through an advanced plateau. Our platform is designed to be more self directed than many other language learning apps. Think of it more like going to a gym than going to a fitness class. We don’t make assumptions about what you need to be studying and when. Rather, we give you the tools to train what you need to work on as effectively and efficiently as possible. You can select from our various tools based on what you want and need to be training at a given time. OUR TOOLS Standard Courses — Frequency-ranked vocabulary and patterns with spaced repetition.
