I have a live app in google play store which has two releases within the same project (one in Arabic and the other is in English - soon I'm going to add a Spanish release).
This is my app: [login to view URL]
The project is to add any free (or very affordable) but easy to use plugin that you are familiar with (of course you can program it manually if you want), which provides a pop-up for the users to review the app and give feedback inside the app itself. Before you go ahead and implement, you need to show me an example of that plugin which should start with a suggested five stars rating that the user can modify if he/she wants. Most importantly, the plugin shouldn't be annoying to the users especially those who have already given reviews.
