It is not only being first. It also is about responding to customers - not fun part is your customers don’t care about your app. They have to use dozens of different apps on daily basis, so when you have customer interaction you better be able to do stuff right there because they might be available in 3 months or next year to talk about your app.

I don’t like all the fantasy about “just talk to the customers” - nah it is not just, it is super hard to get their time.
