"your analysis is not accurate enough. For Both apps "growth" was driven by one main factor: Apple featured them as both app of the week. Apple stopped featuring Meerkat (kind of) and the ranks fell. Apple will stop featuring periscope and the same thing will happen. What will be interesting for both will be to observe what happens after and if growth can get back through different channels. Remember it took 2 years to twitter to take off.. Secret situation was totally different: the app lost is mojo not because Apple did not feature them but because the negative value driven by the app cause its own demise That is the context to analyze this" - Ouriel Ohayon
