What are the best ways to monetize an app without having to put it on the Playstore?

[codescript94]

I know there are several ways to monetize an app, but the most coherent way I know is to put it on the Playstore with Admob active. Do you know of any other profitable way to monetize an app on the web?

You can sell your app through Flippa for one time price. You can also use Amazon to sell your app. You can also publish on third part app markets

Depending on the service provided by the app you can add membership program.

It's very possible to sell the online apps on the web without listing them on the Google play store for sure. I constantly download apps from unknown platforms

A good way to monetize an app without publishing it on the Google Play store is by selling the app directly to customers through your website.
