HelloChinese

HelloChinese is an app similar to Duolingo and Rosetta Stone, where users go through lessons to learn Mandarin. Each section has to be completed before moving on to the next lesson, and at the end of the section, one is tested on their speaking ability. A premium version exists that add immersion lessons with conversations. One can review words they learn. The application does claim that using it ten minutes a day will lead to fluency in three months.
