Threadreaders Unroll Twitter Thread App

Our competitor, if you want to call it that, Thread reader app has managed to become very popular for unrolling threads and although we have made some progress over the last year, we are not growing at a rate that I would have projected based on the viral nature of our service. When you unroll a thread on Twitter you will see it in the comments and people tend to click over to it. My question is, how can we begin to attract more users and thus get in front of more readers on Twitter who will use to unroll as well.
