Bought Streak Repair of Duolingo
It's application of learn languages and free.
It's one of my favorite application and I learn English.
I've learned for 45 days. but, today I forgot to learn.
Of course, I was going to learn.
I went to Karaoke and I watch a movie while ate dinner at my friend home.
I completely forgot it. because I was exciting and wonderful holiday.
When I realized, Time is tomorrow...
I open Duolingo and app showed dialog about "Streak Repair".
Streak Repair is literal meaning.This price is 560yen(about $5).
I was saved. It was truly inadvertent.
You can see discussion about the function.
Thank you for Duolingo team.
I can continue to learning. so it's basic free.
