Seconded. We've made a product in fitness&health niche when all of our competitors (and so we did) think it's essential for users to create an account, fill long questionnaires etc, yet we managed to skip all those things making them optional. Conversion rate skyrocketed on iOS - now we are making same switch on Android app.

It's an app for our wearable (but our wearable is also optional, haha). As said: account is no longer required on iOS, but we are also working on that feature on Android as well.
I'm using the same strategy for my very first product. I noticed the competitors ask way too much information when first signing up. Unfortunately for my product it's not possible to do away with sign ups entirely, but I think I can get close.
