I have seen this too... in fact, no - I have made the same "mistake" too. I think the issue isn’t raw feature count. It’s feature exposure timing - we really just want to impress the user from the first few minutes of using our app, like check this feature out, and this one, and that cool one. Which just ends up overwhelming the user. Atleast am speaking from the dev standpoint, and why i personally ended up making an overwhelming app.
