Kind words are a good reward for work,
but money is better
Pay-to-use helps developers to get paid for their work
How does it work?
1. Code checking in App
It's just a couple of lines in the program, so it won't take much time
2. Download the App
The user tries to use the application for free during the trial period. He needs time to decide if he wants to buy it
3. Secure payment process
After the end of the trial period, paid features stop working. For further use, user needs to pay for the functionality. The payment link must be visible in the app (description part)
When using a payment link, user is taken to the payment gateway to make a payment in a secure way
4. Get paid
Payments for each application are accumulated and once a month the developer receives his/her money. Reporting is also available
