Forgive me, but if the market responds to OP's subscription model (and $4k/mo is not trivial), no ads is a better user experience and there is less dependency on the ad network for revenue.
It's typically much harder to acquire new users than retain current users = subscription model allows you to monetize your userbase over a broader period of time (let's say $5/mo * 6 mo = $30) to a value that would likely be cost-prohibitive. Most users would not spend $30 for this app. But they might sign up for a free trial, and then the $5 subscription.
That’s the thing—I’d consider a limited version of a one-time $5 app, and very likely pay $30—once—to remove the limitations if I found the app useful. But when I see an app demanding subscriptions, I wouldn’t even try the free version. I’d never consider anything that didn’t offer a one-time payment.
the one time payment for a multi year support of software doesn't grow businesses. We just don't see the business of releasing a new version of the same software every two years with some new features and minor refresh, though it still done. It might support a small dev, but you need recurring revenue and subscriptions and ways to increase the ARPU to grow a real business.
Yes agreed. I used to have a one time purchase, but then I kept improving the app, adding more complex features, and the old price didn't reflect all the new work I had put in.
