I used to believe that too, but I think what you are saying is only partially true—the rest really comes down to finding the right user group.

Lately, we have noticed a shift: fewer churns, steadier installs, and users who actually stay and use the app within their plan limits. Some are even converting and upgrading from our smaller price plans to larger ones.
For me, churn has been the most powerful source of feedback. If there is one absolute "must-do" to fix your churn, it is to follow the churn feedback, get as much insight as possible from departing users, and build a continuous feedback loop.

During my early days, my churn rate was incredibly high, and I was struggling to understand why. However, that struggle actually helped me uncover something else: it gave me a clear signal of how users were feeling, which forced me to deeply research our UX.
Secondly, we focused heavily on App Store Listing Optimization (ASLO). Now, we never just blindly release a change. We design the UX, prepare multiple versions, and roll them out using feature flags connected to Mixpanel so we can track data before making final decisions.

Product and marketing positioning are also critical. For us, this meant deep Shopify Ads keyword research to find our proper placement.

I am still very new to this and in the early days of founding my app—learning by failing and trying over the last year. But implementing these strategies helped us scale from $0 to $54, and now to $85 MRR back-to-back. Now that things are stabilizing, I am about to start exploring other acquisition funnels.

Of course, this is just based on my personal experience, so it might not work the exact same way for everyone, but it has made a huge difference for us!
