Con Not a good way to learn a language by itself
It's not your standard learning website with structured courses. Instead, it helps you get more familiar with your target language by translating content when needed.
This can be really beneficial for someone trying to improve their fluency, but isn't going to directly teach you grammar. Readlang is better used to supplement your learning while learning from structured courses.
Con Translations are sometimes inaccurate
This can be a problem when in a given sentence there are multiple words that could go in the text field, and the translation narrows it down to one possible answer, but then it turns out the translation gave the wrong word for that slot. This is particularly an issue with pronouns for some reason.
Con Some sentences are inaccurate
Sentences are from the user-curated database Tatoeba and not all of them are written and checked by native speakers. It is impossible to know the original source of a sentence. Additionally, because they do not control the database they pull the words, reporting individual sentences will not help that much.
Con Not a good starting place for beginners
Clozemaster jumps right in with expecting you to fill in word blanks in the language you are learning.
If you have little or no understanding of the language you wish to learn, it doesn't give you enough information to get started.
Con They do not know the languages they teach
You cannot teach something you do not know. The sentences are taken from [Tateoba], and most of the time, the developers have no clue about what the written sentences say.
Con The alphabets are not taught
There is no problem if you're learning a language that uses the same alphabet as your native language, but if you speak English and you want to learn Russian, Arabic, Yiddish, etc., this app is not a good start for you.
Con This app will ask you fill in the translations of given names in the blanks
The app randomly selects a word from the sentence and ask you translate it, and this word is frequently a given name, like Tom or Stuart. or the names of cities.
