APIs and IFTTT
IFTTT is a nice tool if you are using social media. I don’t use twitter, I don’t use Facebook, I don’t use instagram… so I have to search for an useful application.
I found one after one hours. Because I need a person or a couple who wants to rent my apartment in Berlin. I use the recipe craigslist search and email. Now when somebody is publishing a post on craigslist to find a apartment in Berlin I get an email. Unfortunately craigslist is not so popular in Germany.
