I have used Memrise for about three years to learn Mandarin and brush up on German and Spanish.
What I like about Memrise.
You can ignore words.
You can review difficult words whenever and as often as you want.
You have a list of words that can be transferred to a word or excel document so you can study offline.
They have a daily streak tracker.
They have multiple courses based on topics.
What I don’t like about Memrise
It is simply a word or phrase to drill, rarely grammar is taught.
Different courses often contradict each other.
Most courses are filled with errors, mistranslations and repeats.
The courses are often unorganized. Words are often put together with little rhyme or reason not categorized by topic or experience level.
Anyone can create a course; no quality control exists. Courses claim to be the top 1000 most common words but include a lot of unnecessary entries for advanced learners.
Pronunciation is hit or miss based on course.
What I like about Lingvist German.
Words are taught in sentences or phrases which teaches some grammar.
There is pronunciation for all words and sentences.
It introduces words based on your perceived level.
What I don’t like about Lingvist German.
You cannot skip words for any reason.
There is no word list to copy and study offline, preferably the entire sentence so you can study grammar as well.
The algorithm to determine your level is inaccurate or does not adjust when you are clearly struggling with the words tested. I am on mostly every day and my percentage level keeps getting lower, mostly because I am having trouble with a group of words. I have neither the choice to ignore them or get a list of them so I can study offline.
The ß is required but vowels with umlauts are not. Typing in ss is also acceptable instead of the ß.
