Landscape Audit

As described in the first section, the landscape of language learning tools is vast and diverse. This section analyzes only a few language learning mobile applications, since LanguageBug belongs to this category.

This is also a broad category that includes a large group of services. They were chosen based on relevance and popularity, according to the number of downloads on Apple Store.


These services are long, complex, and may include paid features that I was not able to access. Therefore, these are not exhaustive analyses of their functions, but personal takes on the features I have explored.
