Cons
Con Should be used along with another course/book
InternetPolyglot states on their site that the program is meant to aid in memorization only, and should be used along side other resources.
Con Games do not end on their own
You have to decide when you've had enough playing the games, or set a timer. The games do not end the game for you, so it's not smart about conserving your energy or ending the session when you've learned the material or when you've gone beyond 25 minutes which is the limits of most people's ability to focus.
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.
