What is the meaning of : " equipped " in the icon of streak freeze? Thanks for cooperation.
Yes, pollyperki, you will stay 'equipped' as long as you do not miss a day. When you miss a day, the streak freeze will be used, and you will not be equipped any more. You will have to notice it, because you will not get a notification, not even on Duolingo's website. If you think you have missed a day, you can verify that by going to the Lingot Store, to see if you are equipped or not. If not, you will be able to purchase a new streak freeze. If you do not miss a day, you will stay equipped for ever. :)
That's like saying not to put on a seat belt or safety glasses because sometimes things go wrong.
If I'm trying to keep a streak, I check the lingot store when I sign on to make sure my streak freeze is still "equipped". If it isn't, I buy another one. It might not be perfect, but it is the best insurance you can get.
Until a few days ago, when I missed two or more consecutive days, I had a streak of 600+ and had used streak freeze on many, many occasions without a hitch so, yes, it truly works.
Having said that, losing it was the most liberating thing that has happened to me here since starting in Jan 2016.
