Automatically purchase the Streak freeze to protect your Duo streak!

Duolingo has the concept of a “streak freeze” in the in-app shop by which you can spend the Duo currency you’ve earned by advancing across levels to buy a component in-app which prevents you to from losing your hard-earned streak, just for that day. Once the streak freeze is used, you have to buy a new one from the market again in order to be able to use it. What if you’re out for multiple days in a row and you’re not in a position to play/buy the streak freeze?
