Babbel is like a paid cousin of Duolingo but has its other advantages. The app allows you 40 lessons free for any language which usually covers the important aspects of learning a new language. You have to pay for the tail that is left though. The app has lessons broken down into sub lessons that last for 10 to 15 minutes per piece. It will teach you all the grammar rules as you progress and will challenge you with phrases and words making you to fit them into sentences. The challenges are like filling the gaps just like games that makes learning fun.
