Concept- I was use.this app for earning money we earn few money in this app like 20 to 30 but we can use total net data in it. layout- I install this app amd think I can earn money to watching the video but they give sum point to watch the video.
function- if you want earn money so you can watch the video or install the app if you can install app you earn money but if you uninstall the app you lost your earned money if not uninstall app.your phone storange is full.
usefullness- take my advice dont install the app its vaste of your time or mobile data.
