## What is CL?

THIS APP IS FOR USE WITH THE CL-150 PLATFORM FROM TRANSPARENT LANGUAGE AND REQUIRES ACTIVATION BEFORE IT CAN BE USED.

• Supplemental Vocabulary: Build proficiency by learning thousands of useful words and phrases categorized by topic and presented in an engaging, memory-building format complete with native speaker pronunciation. 
• Core Skill-Building Activities: Work your way through activities that build all four core skills; listening, speaking, reading, and writing.

### 1/5 — Unusable

*2021-10-13, version 1.14.9*

Years ago this app was the foundation of my language studies. Every time they “improve” it, it gets worse! Go back to the Rapid Rote version of years ago.

### 1/5 — Great idea terrible execution

*2018-08-21, version 1.11.0*

This app has a lot of great features but glitch every time you try to use any of them
